Video Frequency

[LipsOfVenom]

I just had a power blackout a few minutes ago and my computer shut off. I turn my computer back on when the citie's power comes back on, and my screen has a lot of white squares that keep flashing. Then the monitor goes black and I get a message saying that the frequency is too high. The message is from the monitor, not the computer; I never even get into windows. Drivers are updated, RAM, LCD, CPU, PSU, GPU, HDD, and everything have been tested on a different setup, and they all work flawlessly. So are the visual artifacts due to a shorted MB?

Have you tried hitting F5/F8 and try booting into safe mode and selecting VGA mode?

if you can then connect another monitor to see if it is your Mainboard or graphics Card.

If you get into Vga mode then you can check adapter refresh frequency and lower it.
