Hi, last night my pc was working fine and now my gpu isn't working. My gpu fans went to 100% and there is no signal.
this has been happening for months, my gpu works in my friends computer but not mine
replaced my psu and motherboard but still happens
i get a windows 45 error and have up to date drivers - using intel graphics as amd gpu doesn't work
my gpu is an amd rx 580 8gb aorus
can anyone help?

Probably isn't a problem with your GPU then. Have you tried DDU multiple times and reinstalling windows? The only way you can know for sure that there is a problem is if it still doesn't work in a fresh install of windows.

Because it works in your friends PC it's probably something wrong with windows and not the GPU. Can you try other GPUs, to see if they have the same problem.
