Hello there, I just installed a brand new AMD 5700 xt. I have a 750w PSU that has given me no trouble in the past whatsoever. When I first installed the card everything was great. I gamed all weekend pretty much nonstop on Total Warhammer 2 and encountered no problems. But last night, while gaming, both my monitors glitched out, showing random static and patterns, but my computer was fully functional behind the visual glitches. I was able to save the game and normally shut down the computer.
I assumed that my GPU had just gotten too hot, as sticking my hand behind my PC confirmed it was very hot. So I let it cool, fired it back up and installed MSI Afterburner to increase the base fan speed. I changed some values (notable allowing application control, and set the curve slightly higher than average. I monitored temps on my side monitor and as far as I can tell the GPU junction temp never got above 100 (although it might have for a brief moment causing emergency shutdown?)Then after about 20 minutes of medium strain gameplay, my monitors go completely black, keyboard + mouse are frozen (numlock or capslock keys won't turn off, but fans are still running) forcing me to restart. I read online that some people were having problems with their new cards, which was solved by undervolting. I set up a undervolt of 1900mHz/995mV and with a power limit of 5%, all of this in the Radeon control panel, with afterburner uninstalled. I also adjusted the fan curve, and everything worked fine for the couple hours I played that night. Now today, I had the exact same problem of a black screen after 20ish minutes, so I did a semi-clean install of Win10 (kept files) and reinstalled drivers and set back up my undervolt. Everything worked fine playing warhammer for 2 hours and 23 minutes before the next black screen happened, with the same systems. I have tried turning all my power and sleep settings off, and I have reinstalled drivers multiple times, fully cleaning the old ones each time. The only big change in between the time it was working fine and now, is that I switched my side monitor running at 1280x720 and a vga>hdmi cord, to a 1080p monitor with DVI>hdmi.
Am I missing something or do I have a bad card? It runs like a dream when it's not crashing so I'm tempted to say something else is the problem.
TLDR: Black screen crash when GPU gets under load for 20min-2hrs, Tried the usual fixes
EDIT: I should mention the last time it crashed it did something new in that it glitched out a little bit on the side monitor before both monitors showed "No signal detected"
