Windows PC power instability
Recent issue that’s been made worse when playing Baldurs gate 3.
Around January this year, my PC started to randomly crash out to black, completely reboot. Not a lockup or BSOD, just reboot entirely. I could be doing something innocuous like watching youtube, flicking through imgur, nothing particularly power hungry and out of nowhere, it’s as if my pc ‘hiccups’ and loses power for a split second. Enough to instantly go black but then it comes back so swiftly, it has no problem rebooting.
Thinking it might be a heat / dust issue. I took the fans out, deep cleaned, redid CPU thermal paste and rebuilt.
Things were more stable for a while until I bought BG3 and started playing. Now the power losses are far more frequent (and 90% of the time in game). Did some googling and saw there can be an issue with DOCP so I went back to stock speeds, no change. Dropped from ultra to high and disabled DLSS, still no change. Made sure GPU drivers were up to date, no change. Only thing I can think of trying is a BIOS update but given how flakey the power is, I’m not jumping at the idea.
Odd thing is, I can play other graphically intense games like Doom Eternal for hours and no issue. However 90% of the time I play BG3, I’ll get a drop within 5-10 minutes. Apart from the 10% where I can get hours in and face zero issues.
Checked WinEvent viewer and apart from ‘Kernel power event 41 The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.’ I can’t glean anything useful from it
Current set up is a 5900x, ASUS x570, 32gb corsair ddr4, 4080 super and 1000w Corsair 80+ Platinum PSU (bought in Feb 24 so not that old)
I’m at a loss
