My PC started glitching out like this and I don’t know how to find the cause.
Columns of red lines dominate the screen, and certain characters aren’t being displayed during startup. This happens with every operating system and every monitor. I can only get into the OS in recovery mode.
Did my CPU get fried? My motherboard? GPU? Corrupted BIOS? How can I find out?
Can this also happen as a power supply is starting to go bad or if your PSU isn’t big enough for all your cards? Seem to recall something similar ages ago.
