System shuts down unexpectedly without any GPU activity during reboot
Hi there, a few months back I upgraded my graphics card from an RTX 2060 to a XFX Radeon 6800XT. It's been inconsistent at times, especially when playing certain titles like Fortnite or Lockdown Protocol on DX11 and 12. Recently, it started running for hours without problems, but sometimes it restarts the whole system every half hour. Games such as Forza or Hunt Showdown work fine even at maximum settings, and stress tests don’t affect the machine. When I mention a screen reset to black, I notice no BSOD and the fans increase as expected. I’ve heard about power spikes on these cards and replaced my PSU, RAM, cables, CMOS battery, thermal paste, and even swapped out the case for better cooling. Temperatures are stable now, and I cleaned the PC thoroughly with a fresh Windows install and driver updates. The manufacturer contacted me about the card, and they sent back a 6900XT, but the problems continue. I ran system checks on RAM and SSD, and undervolting helped most of the time. A few games still have minor issues, and I’m only left with replacing the MOBO and CPU. I checked online for similar complaints, but most posts are outdated or negative. I’m looking for a solution or any tips from others who’ve faced the same issues.
Regarding the PSU, that's the only part you mentioned not addressed, but it seems like a cheaper option might be better. Consider using a GPU brand with sufficient power for your 6900XT. You might get a refund if the PSU doesn't fix the problem—just confirm beforehand. Good luck!
I'm sorry to hear about the ongoing issue. It seems there was a change in power supply settings after sending your 6800XT back, which might have affected performance. I understand AMD suggests a 850W PSU for this setup, and PartPicker estimates you're drawing around 553 watts—though I take that figure with some caution.
There’s plenty of power available. The 553W consumption might just be an average; you could see higher spikes than that. It’s likely a hassle, but you should probably take apart your PC and test it outside the case on a non-conductive surface. If that doesn’t help, it might be time to switch to a different motherboard. AM4 boards are currently on sale, so it could be worth a try. Good luck!
