That code is something of a sign. Not a good one. Report the failure to dell so you don't run out of warranty later as some device has failed and you bear the full cost of repair.

I started getting c4 stop codes a while back and have been trying to track down what is causing the conflict. I'm very frustrated now because the couple times I thought I had figured out what the offending driver was turned out not to be the case.
Any suggestions on troubleshooting methods would be greatly appreciated. These are the things I've tried so far:
1. Run verifyer.exe. That was a dud because my computer refused to start and had to safe boot in and disable it.
2. Disable drivers through Services and Autoruns. I thought I was onto something because my computer ran three days without crashing and was going to start re-enabling them one at a time. Not! The pc crashed before I started that process.
I use AppCrash Viewer to look at Window's minidump files but must admit that I didn't get much from that because most of what is in there is a complete mystery to me.
My pc is a Dell Studio XPS 435T. OS is Windows 7 x64. 12 GB of Ram. Video card is an ATI Radeon HD 4800 Series.
Thanks
