Built a new PC, specs are:
i7 2600K
8GB DDR 3 1600
Asus P8P67 Pro
Vertex 3 SSD
AMD 6950
Corsair 620 watt PS
If I let the PC sit idle or just use it for browsing it works great but as soon as I load a program that taxes the system it just locks up. Not a BSOD, just frozen, sometimes with an audio stutter. The only entry in the event log is:
Event 41, Task 63, Bug check code 0
The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.
If you look it up the likely causes listed are:
Overclocking: Disable overclocking and see whether the issue happens when the system is run at the correct speed. Yes I had experimented with OC but I had this hard lock twice before the OC so the OC was not the cause and I have since reverted to stock speeds and n/c.
Check the memory: Verify the memory by using a memory checker. Verify that each memory chip is the same speed and that it is configured correctly in the system. Here is where I got extensive with the testing. I used memtest86 which creates a bootable Linux that runs a test against the ram. I ran it twice and it both cases the test froze. Once on the first pass and once on the 3rd. I then ran the test with just 1 memory module and let it run for several hours. Both modules passed with no errors when ran individually. I then tried to rerun with both modules using slots 2/4 instead of 1/2 and same result.
I then tried using some desktop tools which are meant to tax the CPU, namely Intel Burn test, OCCT and Prime95. Intel burn test and OCCT cause a hard lock almost immediately while Prime95 runs fine when using small FFT's (which supposed is heavily testing the cores but not ram) but also fails immediately when testing using larger FFT's which utilize some ram. Next step is to run these tests with the individual sticks of ram but worth noting is that I also tried to compress a BR with Handbrake with each individual stick of ram and it caused a hard lock with both. I expect the tests to fail on each stick as well (be confused if it doesn't).
Power Supply: Make sure that the power supply has enough wattage to appropriately handle the installed devices. If you added memory, installed a newer processor, installed additional drives, or added external devices, such devices may require more energy than the current power supply can provide consistently. My PS is 3 years old and I may buy a new one just to rule it out.
Overheating: Check whether the system is overheating by examining the internal temperature of the hardware. I use a water cooler and under a full load during the stress tests the CPU temp doesn't go above 42-43 degrees.
Defaults: Use system defaults, and run the system. Running at all defaults with a clean Windows install.
The one drawback to building a new PC. The hard to find bug. This could be memory or processor or motherboard or PS. Any input would be appreciated!
