Windows 7 Home Premium 64-bit on HP Pavilion P6597c BSOD + Hanging
I bought a refurbished Pavilion P6597c about 3 months ago; it was completely wiped and I loaded Windows 7 Home Premium 64-bit, installed a second western digital hard drive (1 TB), a Nvidia GT 610 (1 GB model) and a Asus Xonar DX sound card. I also installed a 600 watt Thermaltake power supply.
I had installed all critical updates, loaded the most current drivers available directly from HP and other manufacturers.
The system ran perfectly until about a week or so ago, when it started randomly hanging (not a BSOD but the system just locked up/froze), and quite a varietly of BSOD's.
I un- and re-installed drivers; tried different versions, tried switching to the onboard video (in case the card was failing), re-assured internal componests were properly seated, switched anti-virus from Avast to Panda (incase it was a program update conflicting), ran CPUID to make sure the power supply was functioning and that components were not over heating; ran Memtest 86 for half a day to check the ram, and ran Western Digitals Data Lifeguard to test the hard drives. tried sfc /scannow to check that windows files were not damaged/missing and ran TDSSKiller to check for hidden rootkits. Everything seemed perfectly fine.
...except the system still crashed randomly. The crashes/BSODs finally were getting so frequent that I could not load windows, it would hang constantly before even getting to the safe mode option (strangely enough safe mode never crashed). Windows finally corrupted from so many partial/inturrupted boots and unexpected shutdowns.
With Windows unloadable; I finally wiped the drive again and started new 4 days ago, and the problem is now re-emerging. Random crashes and BSODs are creeping back in with greater frequency. It took 20 minutes to get windows running just to make this post.
I am at a loss; I am usually good at diagnosing and repairing these sort of problems, but the BSODs give different errors, usually pointing to various hardware which then test perfectly.
Hopefully someone here can point me in the right direction because I am genuinely puzzled by this one. I made no changes to the system setup, but it went from running perfectly to barely functioning.
Thanks all in advance.
