Few things are more unsettling than turning on your Windows 10 or 11 PC and being greeted by… nothing. Just a black screen. No icons, no taskbar—just darkness. Maybe you see a blinking cursor. Maybe not. Either way, your desktop is gone, and panic starts to set in.

Don’t worry—you’re not alone, and your PC probably isn’t dead. A black screen is a surprisingly common issue, and there are a variety of causes and fixes that range from simple key combos to hardware-level troubleshooting.

In this blog, we’ll walk through the different types of black screen errors and how to fix them, step by step.

Two Types of Black Screens — and Why It Matters

There are two main flavors of black screens in Windows:

1. Completely black screen — No cursor, no signs of life.
2. Black screen with cursor — You can see and move your mouse pointer, but nothing else appears.

The difference matters because a black screen with a cursor usually means your operating system is partially working. It’s often a graphics driver issue or a hiccup waking from sleep. A black screen without even a cursor could point to something more severe, like power or hardware failure.

Quick Fixes You Should Try First

Before you reach for your phone to call tech support, try these simple keyboard combinations:

1. Restart the Graphics Driver

Press: Windows + Ctrl + Shift + B

This command restarts the graphics driver. If the system is still responsive, you’ll often hear a beep and maybe see your screen flicker before returning to normal. If this works, you’re done!

2. The Classic “Three-Finger Salute”

Press: Ctrl + Alt + Delete

If successful, this will bring up the Windows security options screen. From there, you can either log out, reboot, or open Task Manager. If you hit “Cancel,” your desktop may even come back.

Still Black? Time to Power Down

If neither shortcut works—or if your screen is completely black and your PC is unresponsive—hold down the power button to force a shutdown.

For laptops, you may also need to unplug the charger and wait a few seconds. On desktops, you might need to switch off the PSU (Power Supply Unit), wait 30 seconds, then power it back on.

In many cases, this will restore normal operation after a reboot.

What If the Screen Stays Black?

If you’re still staring at the void, it’s time for deeper troubleshooting. Here’s the sequence most IT pros follow:

1. Try a Different Display

Plug in an external monitor or switch display outputs. It’s possible your screen is dead—but your PC is still running fine.

2. Boot Into Safe Mode

Use Windows Recovery media (USB or DVD) to start your PC in Safe Mode. If your display works here, the issue is likely with your graphics drivers or startup configuration.

3. Use External Graphics Hardware

If you have a USB-to-HDMI adapter or an external GPU, connect it and see if the system displays correctly through the alternative graphics output.

4. Replace the Graphics Hardware

If all else fails, your GPU or integrated graphics may be toast. On desktops, replacing the graphics card is relatively easy. For laptops, it may require professional repair—or even full replacement.

How to Prevent Black Screens in the Future

To avoid encountering this problem again:

• Keep your graphics drivers up to date.
• Avoid interrupting the PC while it’s waking from sleep.
• Regularly update Windows.
• Check your Reliability Monitor for errors like “CreateBlackScreenLiveDump,” which indicates a black screen issue was logged.

Final Thoughts

A Windows black screen might feel like the end of the world—but it rarely is. In most cases, a quick key combination or reboot will restore order. And if not, with a little patience and the right tools, you can pinpoint the problem and get back to work.

Still stuck? Don’t hesitate to reach out to your IT support team or trusted technician. Sometimes, it takes a second set of eyes—and a good multimeter.

Yes, you read the title correctly. Researchers have now officially confirmed what is likely the largest data breach in history: a whopping 16 billion login credentials have been exposed in a breach.

So, what does this mean for you and what should you do next?

Why This Is a Huge Deal

This breach isn’t just another unfortunate incident — it’s a massive security risk for individuals and organizations alike. The credentials are already being used for phishing attacks, account takeovers, and credential stuffing campaigns.

In many cases, the stolen data is neatly organized: a URL followed by a username and password. With access to this kind of data, attackers can gain entry to nearly any kind of online account — from Apple and Google to GitHub, Facebook, Telegram, and even government portals.

What You Should Do Right Now

Whether you’re an individual user or an organization, it’s time to step up your security game. Here are immediate actions you should take:

For Individuals:

• Change your passwords, especially if you reuse them across multiple accounts.
• Use a password manager to generate and store complex, unique passwords for each service.
• Enable multi-factor authentication (MFA) wherever possible.
• Consider switching to passkeys, which are more secure than traditional passwords.
• Sign up for dark web monitoring tools that alert you when your credentials are found online.

For Organizations:

• Adopt a zero-trust security model to ensure that all access to sensitive systems is authenticated, authorized, and logged — no matter where the data is stored.
• Implement privileged access management to limit who has access to critical systems and information.
• Train your employees to recognize phishing attempts and suspicious behavior.
• Continuously monitor cloud environments for potential exposure points.

Cybersecurity Is Everyone’s Responsibility

Organizations must invest in protecting their users, and individuals must stay alert and proactive in securing their digital lives.

The message is clear: don’t wait for your credentials to end up in one of these mega-leaks. Get ahead of the threat by securing your accounts today.

If you think security threats only affect Gmail users, think again. All email platforms—including Microsoft Outlook—are frequent targets for cyberattacks. In fact, many of the tactics used by threat actors are the same across platforms, particularly when it comes to malicious attachments.

Microsoft has recently announced an important security update: Starting in early July, Outlook Web and the new Outlook for Windows will block two specific file types that have been used in recent email-based attacks. However, you shouldn’t wait for the update to roll out before taking action.

What’s Changing?

Microsoft will add .library-ms and .search-ms to its list of blocked file types in the default OwaMailboxPolicy. This move is part of their ongoing effort to strengthen protection for Outlook users.

For those who do send or receive these types of files, Microsoft warns that users will no longer be able to open or download them once the block goes into effect.

Why These Files?

The .library-ms extension, which relates to Windows Library files, was part of a known cyberattack earlier this year where hackers used it to expose NTLM password hashes. The .search-ms extension has also been flagged as a risk. Both are now being recognized for their potential to be weaponized in phishing or malware distribution campaigns.

What Should You Do Now?

Don’t wait for the policy update to protect yourself. Until the block is officially in place, these risky file types could still reach your inbox.

• Do not open any email attachments ending in .library-ms or .search-ms.
• Educate your team about the risks associated with these files.
• Review your organization’s email policies and consider proactively blocking these extensions in your own security tools.

Final Thoughts

Email-based threats are evolving, and even less commonly used file types can be turned into dangerous tools by cybercriminals. Microsoft’s proactive blocking of these file types is a step in the right direction—but user awareness is still your first line of defense. Stay alert, stay updated, and never assume your inbox is risk-free.

Your email and phone are under constant attack—and it’s only getting worse. Most users are still relying on outdated security methods like passwords and two-factor authentication (2FA). Google warns that this simply isn’t enough anymore. 61% of email users have been targeted by scams, and almost every American phone user has experienced scam attempts via text.

On top of that, more than half of U.S. users have experienced a data breach in the past year.

Many people haven’t taken the step to upgrade to stronger and more secure alternatives like passkeys or social sign-ins (e.g., “Sign in with Google”), which offer enhanced protection across your entire digital life—not just Gmail.

What Makes Passkeys Better?

Passkeys are emerging as a powerful replacement for passwords. Unlike passwords, which can be guessed, reused, stolen, or phished, passkeys are stored on your device and unlocked with something you already use—like your fingerprint, face ID, or device PIN.

Here’s why they matter:

• They can’t be phished – There’s no password to steal.
• They’re simple to use – No remembering or changing passwords.
• They work across devices – You can log in with your phone even on another device.
• They’re hardware-tied – Your device becomes your secure digital key.

The FIDO Alliance and tech giants like Google and Microsoft agree: passkeys are phishing-resistant, secure by design, and a much-needed upgrade in the fight against cybercrime.

What You Should Do Now

Here are immediate steps you can take to improve your digital security:

1. Add a passkey to your Google account – It’s quick and easy, and protects you from phishing.
2. Stop using SMS-based 2FA – Switch to device-based authentication like Google Prompts or Authenticator apps.
3. Avoid reusing passwords – Even for non-critical accounts.
4. Be skeptical of unsolicited messages – Especially those with links or asking for credentials.
5. Access sites directly – Don’t trust links sent via email or text.

If that isn’t reason enough to take action, remember: once someone has your credentials, they often don’t need to hack anything—they just log in.

Cybersecurity experts are warning about a new phishing attack that’s tricking financial professionals—like CFOs and executives at banks, energy companies, and insurance firms—into installing real software used in a harmful way.

What’s Happening?

One example pretends to be from Rothschild & Co., offering a “strategic opportunity.” It includes what looks like a job offer or important attachment—usually a PDF—but when clicked, it secretly sends the user to a fake website.

From there, the attacker:

• Creates a hidden user account
• Turns on remote desktop access
• Makes sure the tool stays active even after the computer restarts
• Hides any evidence so the victim won’t know anything happened

Why This Matters to You

Even if you’re not in the financial industry, this kind of phishing attack can target anyone in your organization. And cybercriminals are now using legitimate, trusted tools to avoid getting caught.

Plus, these scams are part of a much larger trend:

• Fake job offers
• Fake invoices from Apple Pay or Microsoft
• Phishing websites disguised to look like Google or Notion
• Malware hidden in documents or images

And behind it all? A growing market of Phishing-as-a-Service (PhaaS)—where scammers can literally subscribe to easy-to-use phishing kits (just like signing up for Netflix) that come with tech support, updates, and dashboards to run scams.

What You Can Do

Here are 5 quick tips to stay safe from these kinds of attacks:

1. Pause before you click – Unexpected emails about job offers or urgent invoices? Don’t rush. Double-check with the company directly (not using info in the email).
2. Avoid opening ZIPs or links from unknown senders – These files may look harmless but can quietly install malware.
3. Be suspicious of CAPTCHA challenges in unexpected places – It could be a trick to bypass filters.
4. Look closely at email addresses – A message from “company@nifty.com” might seem legit, but always verify the domain.
5. Report suspicious messages – Let your IT or security team know immediately. Early reporting can stop a wider attack.

Final Thoughts

Today’s phishing attacks are no longer just clumsy emails with spelling mistakes—they’re well-designed, use real tools, and are hard to detect.

The Threat: Smishing & Vishing Campaigns

The FBI has issued an alert that cybercriminals are using text messages and AI-generated voice recordings to impersonate senior U.S. government figures. The goal? To build trust and then trick recipients into clicking malicious links or revealing sensitive data.

These actors often claim to be transitioning to a different messaging platform—perhaps a common excuse like “Let’s move this to Signal/WhatsApp”—before sending a malicious link. Once clicked, the attackers can steal login credentials or install malware to gain access to personal or official accounts.

Even more dangerous, once attackers compromise one account, they often use it as a launching pad to impersonate the victim and reach out to others in their contact list.

Smishing, Vishing & Spear Phishing — What’s the Difference?

• Smishing: Phishing attempts via text messages (SMS/MMS). Scammers often use fake numbers or impersonate familiar contacts.
• Vishing: Phishing through voice calls or messages, increasingly using AI-generated voices to sound like trusted individuals.
• Spear Phishing: Highly targeted email scams that often precede or accompany smishing and vishing efforts.

What makes these attacks especially dangerous is their personalized and convincing nature, often leveraging public data and social engineering tactics.

How to Spot a Scam

Cybercriminals are getting smarter, but there are still red flags you can look for:

• Unfamiliar Numbers: Always verify the identity of the sender or caller using a trusted source.
• Unusual Language or Requests: Is the tone off? Are they asking for urgent help or money? Be skeptical.
• Suspicious Links or Attachments: Never click or download anything unless you’re absolutely sure it’s legitimate.
• Visual/Audio Inconsistencies: Look for distorted images or strange voice characteristics—like unnatural tone, lag, or incorrect phrases.

Steps to Protect Yourself and Your Team

1. Verify Before You Trust
   Double-check requests—even from people you know—via a trusted method or contact.
2. Don’t Share Sensitive Info
   Never share login credentials, verification codes, or personal data through unverified messages.
3. Enable Multi-Factor Authentication
   And never share your MFA codes. If someone’s asking for them, it’s likely a scam.
4. Set Up a Family/Friend Verification Phrase
   Create a “safe word” to confirm identities in case of suspicious contact.
5. Be Cautious with Downloads and Links
   Avoid clicking links or downloading files from unknown or unverified sources.

If you use Google Meet, you may be at risk to a new malicious pop-up attack.

A newly identified scam, ClickFix, is a stark reminder that social engineering tactics are still alive and thriving. This threat doesn’t need AI to work; it just needs your trust and a few keyboard shortcuts.

What Is ClickFix?

ClickFix is a pop-up attack that mimics a technical issue, often pretending to be a problem with your microphone in Google Meet. The goal? To convince you to copy and paste a line of PowerShell code into your Windows Run dialog. Once executed, this code silently downloads malware onto your device.

The attack typically begins with a fake Google Meet invite, often including terms like “google” and “join” to appear convincing.

But there’s a catch: Instead of asking for a login, the page displays a fake error like “Microphone Permission Denied” and instructs you to fix the issue by copying a block of code and running it manually. The steps are usually:

1. Click a button to copy a “fix.”
2. Open the Run command (Win + R).
3. Paste the code (Ctrl + V).
4. Hit Enter.

How to Stay Safe

Fortunately, avoiding ClickFix and similar scams is easy — if you know what to look for:

• Never run commands from untrusted sources. If a website tells you to open the Run box and paste in text, it’s a scam. No legitimate tech support or app will ask you to do this.
• Check the invite details. Watch out for strange URLs, especially those that mimic well-known services but aren’t hosted on official domains.
• Use security tools. Up-to-date antivirus and browser protection can catch some of these threats — but not all. Awareness is your best defense.
• Report suspicious emails or links. If you’re unsure, forward the message to your IT team or security provider for review.

Final Thoughts

Remember: If you ever see an error message telling you to open Run and paste in code — back out immediately. Close the tab, delete the email, and move on.

Google’s new AI Overviews feature is designed to give quick, AI-generated answers to your search queries. While it might seem helpful, it also raises some serious data privacy concerns.

How It Works

When you search with Google while signed into your account, AI Overviews use your query to generate a summary. But here’s the catch: unless you change your settings, Google saves your searches, the AI responses, your feedback (thumbs up/down), and other data like location and device info—for up to 18 months.

Your Data Footprint Grows

Because this feature is tied to your Google account, it could access:

• Your Gmail content
• YouTube watch history
• Google Maps check-ins
• And more

This creates a deeply personalized profile—which could be vulnerable if your account is hacked, subpoenaed, or if data leaks.

Can You Turn It Off?

You can’t fully disable AI Overviews yet, but there are ways to limit them:

• Use a Chrome extension like Hide Google AI Overviews
• Add &udm=14 at the end of Google search URLs to get only regular results
• Switch to private search engines like DuckDuckGo or Brave

Final Thoughts

AI Overviews may save time, but they come at the cost of your data privacy. If you’re concerned about how much Google knows about you, it might be time to adjust your settings—or consider a different search engine. Have any questions? Reach out to us today at 703-790-0400.

It might surprise you to hear this, but your email, social media, and bank passwords could be floating around the dark web right now—and criminals can buy them for less than the cost of a dinner out.

Yep, just $81 a week is all it takes for cybercriminals to subscribe to a stream of stolen passwords and other sensitive data, and they’re using it to break into personal accounts like yours.

How Are Hackers Getting Your Info?

It’s not always some big, sophisticated hack. Often, it starts with a sneaky piece of malware called an infostealer—software designed to silently collect your saved passwords, credit card details, and even those special codes you get when using two-factor authentication (2FA). All of this gets sold on shady websites or private messaging groups like Telegram.

What does this mean for you? If you’ve ever reused a password or saved one in your browser, you could be a target without even knowing it.

It Costs Them Little—but Can Cost You a Lot

While hackers are spending just a few bucks a week, the damage they cause can be massive. Once they have your info, they can:

• Empty your bank account
• Lock you out of your email or social media
• Use your identity to scam others
• Access your work systems, putting your job at risk

It only takes one bad click or weak password to open the door.

How to Protect Yourself

Here’s the good news: you can fight back. Here’s how:

Stop using passwords when possible – Many services (like Google, Microsoft, and Apple) now offer something called passkeys, which are way more secure and can’t be stolen like traditional passwords.

Use a password manager – Let it create and store strong, unique passwords for you. No more repeating the same one everywhere.

Turn on two-factor authentication (2FA) – This adds a second layer of security even if someone has your password.

Think before you click – Be extra cautious with unexpected emails, texts, or links.

Bottom Line

Hackers don’t need millions of dollars to pull off a cyberattack—they just need a few stolen passwords. But by changing the way you protect your accounts, you can stay one step ahead. Reach out to us today at 703-790-0400 or sales@optfinity.com to discover how OptfinITy can keep your network secure.
