White screen after booting to the desktop

i have  a  solution

First of all White Screen causes most exe files like Spyware or viruses the best way to fix it is to boot

on a winpe CD or DVD from winpe searching the malware that loads at Startup

if you dont know which file is it try to start taskmanager at logon

to do this go to system32 and then make a copy of cmd.exe and rename the copy sethc.exe and replace the current sethc after this reboot let it Login normally and then Switch user by pressing a win +l and then hit shift 5 times then a command prompt should appears then type taskmgr.exe then find the process and kill it and remove it via msconfig or winpe sorry for my bad englisch

Hi,

1.       Do you receive any error message?

2.       Have you made any changes to the computer prior to this issue?

There is a possibility that some third party programs installed on the computer is causing the issue.

Method 1:

Step 1:

You may try to boot the computer in safe mode. Refer the following link.

Step 2:

If this issue doesn’t occur in safe mode then you may perform a clean boot. Refer the following article.

NOTE: Once you are done with clean boot, please follow step 7 in the article to set your computer back to normal startup.

Method 2:

You may try to perform SFC (System File Checker) scan on your computer and check. Refer the following article.

Method 3:

I would also suggest you to scan your computer with Microsoft Safety Scanner, which would help us to get rid of viruses, spyware, and other malicious software.

The Microsoft Safety Scanner is a free downloadable security tool that provides on-demand scanning and helps remove viruses, spyware, and other malicious software. It works with your existing antivirus software.

Note: The Microsoft Safety Scanner expires 10 days after being downloaded. To rerun a scan with the latest anti-malware definitions, download and run the Microsoft Safety Scanner again.

Note: Any data that are infected may only be cleaned by deleting the entire data, which means there is a potential for data loss.

Hope it helps.
