PSU could also be failing, overheating or not supplying enough power. Those are well known for dying
I don't think that's it, most of the time the game just crashes, the display never shuts off or anything like that.
Because the GPU isn't receiving enough power and craps out. It's not unheard of, and would explain why you get the same problem and two installs of Windows with two different videocards.
You've ruled out everything else.
Yeah, had nothing plugged in but keyboard and mouse, dota 2 still crashed. How can I test my vram like you suggested earlier? Any good way to see if I have a faulty psu?
Just try another another PSU and see what happens. Unless you've overclocked the videocard, I highly doubt it's the card.
Try Kombuster, it's a bit dated though.

These are the best two I've found, they find issues immediately, although you may get false positives and they aren't easy to configure. It's all commandline from CMD

I assume your drivers and Windows patches are up to date.
I'd also make sure your motherboard BIOS and any firmware and drivers are up to date. Check the manufacture website.
