Mysterious PC Glitch (youtu.be)

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?

Definitely bad VRAM on your GPU.

That looks EXACTLY like my R9 280X did when it died. My solution was to put it in the oven, which brought it back to life, and then running it undervolted and with an aggressive fan curve to make sure it stays cool.

Wow I had to look up the oven fix, that's crazy that it sometimes works! I'm not going to try it though. I might get a new GPU.

Thanks for the answer!

You have nothing to lose at this point, so you can go for it. Just run a cleaning cycle on the oven afterwards to get rid of the nasty fumes.

My R9 280X died again about a year after I did this, but I got through the mining craze of 2018 with it.
