This PC is two years old and essentially started to crash out of the box. I put up with it for about a year-and-a-half because the crashes were somewhat infrequent, maybe occurring every two to three weeks. About three months ago I had become fed up with the crashes and purchased a software support contract with Dell. Although I had performed multiple diagnostic tests on my own to search for hardware failure (I have never found any issues), they made me rerun those same tests to prove to them there were no hardware issues. After the diagnostics came back clean, they told me I would have to reformat the hard drive and reinstall Windows (which came as an OEM install). The good folks at Dell assured me this was the only fix, and while I did not really agree with them, I complied with their suggestion. Unfortunately, performing a wipe and load did not fix the problem.
The PC in question continues to experience the occasional BSOD. It was suggested to me that perhaps I should update the video driver on the PC. So, a few weeks ago I used a program called Driver Fusion from Treexy to remove all AMD components that I could. I then downloaded a more recent version of the ATI Radeon HD 4200 display driver, v 8.970.100.3000, released 07/2012 (my previous version was v 8.850.0.0, released 04/2011). Despite updating the driver, the PC has crashed 3 or 4 times since. So although it was probably a good idea to update the video driver, this alone was not enough to fix the issue.
Trying to rule out a faulty memory, or a bad DIMM slot, I ran memtest86+ for about 16 hours last weekend, checking each individual memory stick in each slot for 8+ passes. No errors were found.
When I run bugchecks on the Dump Files, the results typically state that the crashes were probably caused by Ntfs.sys, ntkrnlmp.exe, and win32k.sys. Trying to isolate a bad driver, I ran Driver Verifier continuously for four days, trying to apply stress to the third party drivers. However, I could not crash the PC while doing this, so I have yet to isolate a potential bad driver.
Basically, I havenít been able to verify if this is a hardware issue, a driver issue, or something altogether different. What exactly could be causing this? I have attached a zip containing the dump files. I have just about had it with this PC, so any help would be greatly appreciated!
