I’ve had an ASUS CM6870 for about a year now and I’ve been encountering the same issue ever since I bought it.
Some current specs:
- Windows 7 Ultimate 64-bit
- Intel i7-3770 CPU @ 3.40GHz
- 16GB RAM
- 2TB HDD (replaced after stock one fried)
- EVGA GeForce 660GTX (replaced stock GeForce GT640 3GB )
- 950w Power Supply (replaced stock 350w)
The issue I’m having is the computer just randomly freezes (no buzzing sound) which forces me to perform a hard shut down every time – It happens most often when I’m gaming, and most often when I Path of Exile. Going to the Event Viewer I find this error: Microsoft-Windows-Kernal-Power Critical error (EventID 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 run both GPU-Z and Core Temp, and when I last logged a file (after about an hour of play) my computer temp was sitting at 52C, so it’s not an overheating issue, and the wattage is fine. I've tested each stick of RAM, and the issue continues no matter which combination I have. All drivers are up-to-date and I have no other issues.
So, I'm pretty much lost as to what could be happening, even after replacing the video card and power supply I still have the same issue. This happens 2-3 times a day and I believe I'm pretty much just killing my computer having to hard shut down each time. Could it be a Motherboard or CPU issue? I’ve exhausted all attempts to resolve the issue aside from replacing every part in it, so any professional advice would certainly help.
