Hello everyone,
About a month or two ago, I upgraded my PSU and my GPU. Since then, the system works fine except for one problem. It will randomly shut down immediately without warning (black screen then turns off). Strangely enough, the PC doesn't shut down under heavy load. Just yesterday, It cashed while playing Mount and Blade: Warband, which is more than capable of running on my PC. However, a few weeks before, It crashed while simply idle or editing a document.
The system has (surprisingly), never crashed while playing intensive games such as Battlefield 3 and 4 or Far Cry 3.The crashes are really random, and have no warning such as fps drops or any error. I have already tried to disable restart on system failure, but there are no logs or errors to be seen when I start it up again.
However, when I look through Windows Event Manager, I see around 19 critical error logs with the tag being Kernel-Power. Most of the errors are exactly the same, except for a few that have a different powerbutton timestamp value (most are 0), and one log has a BootAppStatus of "3221226513". I will attach screenshots of the errors in case they will help.
My PSU is powerful enough IMO and according to most PSU calulators (which give me ~350W minimum, which is way off IMO
). Instead, my GPU (XFX 7870 GHz DD) says 500W minimum. I have a 550W PSU, so I have no idea if its faulty or is its a problem with my house's power. In case you need them, my specs are:
-1-- NZXT HALE82-N 550W PSU (Non- Modular)
-1-- ASRock B75-DGS Motherboard
-1-- i7 3770 CPU
-1-- XFX R7870 GHz DD Edition
-1-- Toshiba 1TB HDD
-1-- DVD Multi drive
-1-- USB/memory card reader
-2-- 4GB (DDR3?) RAM sticks (8GB total)
-4-- Fans (120mm?) (1 intake, 2 exhaust, 1 heatsink/cpu fan)
I'd appreciate your help! Thank you!
