I have a computer that when a specific user logs in it will randomly lock up on them. For instance it has locked up while they are using it, and while using different applications. It has locked up during the night after they have logged out (but kept power on). It has locked up while in screen saver mode upon returning from lunch. These lock ups occur maybe once or twice a week. I took the computer out of their building to my office and ran it for 2 weeks and could not duplicate the locking up, even when logged in on their account. Did a complete reinstall of Windows 10 just to be safe and ran for another week with no lockup. After returning it to them it locked up again within 4 days of their using it.
It is a Dell OptiPlex and Dell keeps saying it's a Windows issue. Has anyone come across this?
