Windows task bar blinks startup


Last night our computer, when restarted, it stood blinking all the time no access to desktop or apps.  Tried restarting windows explorer from task mananger, disabling all startup apps, some services to no avail (still blinks constantly).  If we run in safe mode there is no blinking and windows Explorer opens - all seems normal.

One of the main culprit we were googling  seems to be display driver, we deleted the display driver and reinstall but windows only installed a Microsoft generic display adapter, not the HP drivers that came with it.

What can we do to fix this?
(note we did notice, that a user clicked  bulkfilechanger (from nirsoft) and comodo security detected it and ran it in “containment”.  After closing the apps, the user could not left-click anything to run and a message kept appearing which didn’t right down - after restart the computer started blinking).

We have windows 10 pro & latest update.

Also found that a culprit can also be Norton AntiVirus, iCloud, and IDT Audio - we hace icloud, but can’t seems to uninstall it since can’t open control panel.

I have seen this once before. Open System in Control Panel and find the tab Restore to a Prior point. Do that and restart.

it's likely a Malware attack.

Remember cannot open any “windows” like Explorer or Control Panel.
RaminTechnical AdvisorCommented:
The symptom is like a Malware attack. you need to full scan the PC.  try with a Bootable antivirus.

After that you can try to repair Windows.

How can I run the anti-malware apps if no windows “run”? Also what do you mean by   “repair”
RaminTechnical AdvisorCommented:
That Antivirus Bootable media is called Rescue Disk.

something like this link.

You have to run an Antimalware on a clean PC,  then  create a Bootable media (CD/USB) using that Antimalware program. then put in in your optical drive/USB and boot from it.

you can also find some Antivirus / Antimalware on a bootable CD/DVD too.

Also what do you mean by   “repair

I was trying to say if after scanning that PC and deleting malwares some Windows file was corrupted then after Cleaning Malware you can perform a Windows repair (running some commands like SFC /SCANNOW or using a Windows media to do a repair install) to fix Windows file.

You said you can start in Safe Mode and all normal (above).

So try the System Restore to see if that works.

You can run Malwarebytes in Safe Mode to check for viruses.

If this still does not fix it, try running Safe Mode with Networking. Then run a Windows 10 Repair Install from the Media Creation Link

Windows 10 is running, so click on the Download button (not Upgrade Button, select Open (Run) but NOT Save. Allow the program to run. Allow drivers to update. Then select Keep Everything.
