This is my first post here due to the fact that I recently registered. I've noticed alot of posts regarding event ID 41 issues and I am posting here because I am going crazy trying to figure out why the computer randomly reboots and the community here seems very helpful. I recently built the system with all the components below:
Intel i5-2500k with no overclocking
Cooler Master Hyper 212+ (in Push-Pull) – added 12/22/12
Asrock Z77 Extreme 4 Motherboard
G.Skill 8GB (2*4GB) 240-pin Sniper Memory (1600MHZ @ 1.25 volts)
Seasonic M12II – 620w power supply
XFX Radeon HD 7850 2GB – added 12/26/12
Cooler Master HAF 912 Case
Hitachi 1TB Harddrive SATA
Seagate 1TB Harddrive SATA
Samsung 500GB Harddrive (primary Drive) SATA
OS: Windows 7 x64 Professional SP1
I am going crazy trying to figure out why the computer randomly reboots. The random reboots often occur when browsing the internet. The weird thing is that I am able to play games that tax the CPU more like Saints Row 3, Far Cry 3, and Hitman Absolution without a problem. When the computer reboots there is not any BSOD and there are no dump files from the crash. The only place that indicates that anything happened is the event viewer. The only thing that it says is that an event ID 41 (Task 63) occurred, which is described as “The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly”. All of the Details for every random reboot are the same and are described below
The random reboots were occurring before the instillation of the new graphics card and the aftermarket CPU Cooler. The random reboots continued after the parts were changed and dust was cleaned out.
So far I have ran memtest 86+ and Window memory checker – Both Sticks and every slot passed the tests. I then began testing the cpu with prime95. During all of the tests the maximum core temp was 58 degrees Celsius and the minimum was 31 degrees Celsius. The temperature readings were taken with Coretemp and HWmonitor. The temp readings lead me to believe that it is not a cooling issue. I ran the Small FFT test without a problem for three hours, I then ran the Large FFT test (two times total) and the computer crashed both times at different portions of the test. I have yet to run the blend test. I am thinking of doing a fresh install of windows 7 on an extra 250gb HDD, reinstalling the latest drivers for everything, and running the tests again. So I believe that the problem could be either the cpu, psu, drivers, the hdd, or a problem with Windows itself.
If there is any information that you can provide on how to solve this problem it would be greatly appreciated.
