Question gpu not working again

[benmills45]

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
since i built my pc i have nothing but problems
can anyone help?

My 580's , Sapphire Nitro's did this , replacements have been fine for months now.

also - i have recently exchanged the psu and motherboard , both brand new as i thought they were the problem
My mate used a 8 pin connector but mine is 6+2 , is there a difference?
