Hello, my ASUS TUF Gaming 3070 OC (that I bought off of Ebay in November 2022) has been acting up for about ~4 months now, before I would be able to play as much as I want with no black screen, but for these past 4 months any GPU intensive game just gives me a black screen after about 10 to 40 minutes (depending on graphics settings),When I get the black screen I can still click use my keyboard and mouse (can also hear audio) and can also use shortcuts like Alt+F4 to exit spotify, etc. I've basically confirmed that this is a GPU issue by using my old RX 580 to try to replicate the issue and couldn't.
This issue seems to sometimes stop or take longer to happen when I lower power consumption in MSI Afterburner, by the way I don't think the issue is happening because of temps because I noticed that the crashes are happening even when I am averaging 77C. (By the way I have to force shut down after black screen happens)
This issue first started happening when I started playing The Last Of Us Part 1, and now it happens in basically most GPU intensive games like FIFA, Spiderman Miles Morales and Forza Horizon, in these games I can sometimes at most play an hour with no blackscreen but for example when I play games like Overwatch 2 I can play for as long as I want with no black screen.
PC Specs: Asus Tuf Gaming RTX 3070 OC | Ryzen 5 5600x | Aorus B550 Elite v2 | RM1000x PSU | 8x2 GB 3000Mhz corsair ram
Some fixes I've tried: Many different GPU drivers (Using DDU)
Different Bios versions
Using 2 PCI-e 8 cables instead of 1
Undervolting
Using 1 stick of ram
Re-seating the GPU Changing
PCI-E speed to gen 3
Disabling XMP and PBO
Formatting Windows 10 and Installing Windows 11
In reliability history I see that when the PC black screens I get a DWM.exe appcrash and also a livekernelevent 14, only thing I haven't done now is change the thermal paste in the GPU but I think that's unlikely to fix the issue since it rarely ever goes above 82C, and I don't think I can RMA since I got it off of ebay even though it's still under warranty. What can I do at this point? Any tips would be appreciated, thank you!
