Hello. I have been having problems with frequent shut downs, without blue screen, on a newly-built PC. They are classified in Windows as "Event ID 41, Kernel-Power task 63" errors with no extra information or dumps. Triggers have included:
-- Downloading basic programs (using a bulk web installer from Ninite, so unclear which specific programs)
-- Opening graphics card controller program
-- Rendering levels in Guild Wars 2 and Civilization 5
-- Logging onto Windows account
The events are correlated -- that is, conditional on one shut down, I might get several in a row while trying to log into Windows. At other times, however, I have gotten 4-5 hours of uninterrupted use playing less intensive games (League of Legends), browsing the internet, streaming HD video, etc.
I have tried:
-- Uninstalling "redundant" drivers (e.g., the graphics card sound driver that might interfere with Realtek HD audio driver -- saw this in other similar threads)
-- Reinstalling all drivers on a fresh install of Windows, one-by-one (crashed after LAN and graphics card but before chipset, etc. -- but given the spacing between shut-downs, this didn't seem very solid evidence that either was the culprit)
-- Replacing the power supply with a friend's much larger wattage PSU (650 --> 1000 W); so I don't think it's under-powered
-- Rewiring everything in the case
And run some diagnostics:
-- Checking internal temperatures; everything was under 55-60 C
-- Windows built-in memory test, all clean
My hardware is
Processor - Intel i7 4790k
Mobo - GIGABYTE GA-Z97X-UD5H
GFX - MSI N760 TF 2GB GTX 760 (factory overclocked)
HD1 - SanDisk UltraPlus SSD 128GB
HD2 - WD 1 TB
RAM - 16 (2x8) Kingston
PS - Rosewill 650W Modular (replacement tried was 1000W, I forget the brand)
Case - has 3 fans, 2 of which plug into Mobo
[I have not overclocked anything myself]
Important software:
Windows Embedded 8.1 Industry Pro
Drivers from Gigabyte website (http://www.gigabyte.com/products/product-page.aspx?pid=4950#dl) and MSI (basic GeForce driver)
I am unsure how to proceed other than replace parts one-by-one. I was wondering if anyone had more experience with such problems and had a better idea of where to look next. I can try to provide additional information conditional on my computer's starting (it should be able to run long enough to check some error reports, etc.). My current plan would be to try without the graphics card. I have also not attempted to update the BIOS, which is 2 versions behind (what I have is current as of this May).
Thank you very much
