  1. I had a major PC crash several weeks ago and MPC, the PC's manufacturer replaced the Intel 875P MB, the RAM (DDR SDRAM 512x2) and the CPU (P4\3.2) and the power supply. Everything seemed to be OK but, I think due to a problem with my USB HP scanner, the PC crashed again and would not boot up Tech support had me pull one of the 512 modules out and the PC did fire up and run chkdsk, with a number of repairs. Another RAM module was sent and Ramtest shows both chips to be good. My hard drives are Seagate SATA 160MB Raid 0'ed to a 320MB drive. The disks appear to be OK and I've cleaned out my swap file and let XP create a new one. The PC boots up and XP loads and seems to run normally. Here is the problem. On almost every shutdown (command or power button), as the screen shows "Windows is shutting down" I get a BSOD with a Stop 050 error. I'm not sure what the cause is, although, disabling my resident virus scanner may help (can't swear to it). I've disabled the Windows Exit sound as well. Everytime that I think I have it licked, bam, the next shutdown the same thing happens. All of my minidunp files read the same so I'm hoping that someone can give me a lead on this. One odd thing is that with the DVI port connected, the BSOD screen shows as a two sided page with small, almost illegible text. With the analogue port connected, the screen is normal. I've considered everything from uninstalling my Nvida video drivers and/or my Creative audigy drivers to pulling the video card and slipping an older PCI Nvidia card in to (gulp) reloading Xp from scratch (my licensed copy was SP1 in 2004 and I manually updgraded to SP2 long ago, so I may not be able to try a Windows Repair). Before I consider a complete reload, I want to try to be sure that I don't have either a driver issue or hardware issue that can be resolved. The video card is an AGP Nvidia GeForce 5950 Ultra. Sorry to be so long winded. Here is the minidump. Any help would be greatly appreciated.

    Quick update. I tried running the PC with only one 512MB memory module at a time with no change. The RAM appears to be good. I also pulled and reseated all of my cards, including the Nvidia AGP video card, updated the Nvidia drivers and uninstalled my antivirus program. Unfortunately, the same BSOD occurs on shutdown but it is now happening while XP is on "saving your settings". I'm getting a sinking feeling that I'm going to have to do a complete system recovery but, again, any thoughts on the debug report would be helpful.
