Hi guys let me make this story short and also included what I've done so you guys can help me, please


I got this RX 580, I was using it with a crappy 800w PSU, I was using a 6 pin connector because that is what the PSU had. I Oc the card to 1400mhz and Undervolted, all was great I can play games all normal, One day what I was expecting happened, the PSU died, I bought a used Corsair cx 750w 2017, and the problems started to happen, I get a black screen that forces me to restart my pc, I get this problem in rainbow six siege and in uniengine heaven, when the game is about to start, sometimes I can play sometimes I can't, today was the first time I was playing and the black screen happen during the game, if I OC to 1400mhz I get the black screen. In the case of uniengine i could OC to 1400mhz and I ran the benchmark, weird thing is that always it's in the same scene that I get the black screen, one thing that I want to make note of, is that I play tomb raider for 3 or 4 hours and all good, I don't get any problem, so I don't know what to think if its the PSU or the GPU that could have been compromised by the damaged PSU. Before this new PSU all was good.


Things I have done:


DDU and install an older driver (19.5.2)
Install a new windows in another HDD
Change the thermal paste

Reset Bios

Cleaned Pc slot and reinstalled the GPU
Use a different PCI line of the psu (it has 2 lines)
Change the power outlet



Systems specs:

i7 3770
rx 580 4gb
