Computer freezes, blinking white black rectangle on screen

[zmeu18041]

Dear Support,

My computer freezes while I am working. The screen starts blinking with  white black rectangles. The only solution is to restart the computer. The Windows 11 Event section shows the following errors:

Thank you for feedback.

Hi zmeu18041,

Thank you for posting in our Community and attaching the Intel Scan logs. I understand that your computer is freezing while in use, with the screen displaying blinking white and black rectangles, and that the only current solution is to restart the system. I also appreciate you sharing the Event Viewer errors related to Intel Graphics Software. This will be very helpful in troubleshooting. To assist you more effectively, I’d like to clarify a few details:

1. Do the freezes occur consistently with certain applications or during specific tasks, or is it random?

2. Have you noticed any other system behaviors prior to the freeze, such as fan noise changes, unusual temperatures, or system slowdowns?

3. Could you let us know if you’ve recently installed any new software, Windows updates, or drivers before this issue started?

4. Are you using any external monitors or peripherals that might be connected during the freezes?

5. I've reviewed the steps you've already taken as outlined in this thread. To build on that foundation, what other troubleshooting approaches have you tried?

Once I have this information, I can conduct further analysis and provide the next best troubleshooting steps to resolve the issue. I’ll also keep you updated throughout the process to ensure a smooth resolution. 

Have a nice day!

Best regards,

Von M.
