The worst I've seen was the CPU Cache Fix that "did not go well" if you had an AMD processor. Fortunately on that one I pulled the power plug and battery before the computer burned itself out.
This one: came in to find the tower computer monitor was all-black. I have HDMI and VGA output on both the computer and the monitor, monitor connected via HDMI. Rebooted the computer and power cycled the monitor. Still nothing. In a "This idea is so stupid it has to work" move I hooked the monitor up using the VGA. That worked. Ran "Settings", reloaded the drivers, all the normal stuff. The HDMI selection showed the Backdrop, but you could not open an application on it. On VGA- noted the cursor could be moved off screen.
Went to settings, check off "Duplicate These Displays", which is used when you have TWO physical monitors. That worked.
Then my wife told me that her Sister's computer was doing the exact same thing mine was, after being updated and rebooting.
I'll be visiting with my VGA cable.
