Hello all and thanks in advance for any help! Windows XP Pro, 768Mb PC2100 DDR, 80 GB WD HDD, 400w power supply Windows is crashing randomly, sometimes just after boot up, sometimes when I'm in the middle of something such as a virus scan, sometimes while idle, occasionly during the boot. Some BSOD's point to Driver_IRQL_Not_Less_Or_Equal, I also sometimes get Page_fault_in_Nonpaged_Area. Some of the BSOD's refer to a certain file, here are the file names that I have seen listed on different occassions; naiavf5x.sys (McAfee file), i8042prt.sys (keyboard driver I think), win32k.sys, ntfs.sys. I ran Memtest 6 times and found 0 errors. I have 2 sticks of RAM, I tried taking each one out and leaving the other and booted with no improvement. I ran chkdsk and I think it found 0 errors, the results were on the screen for about 2 seconds and then the PC rebooted. It also said the NTFS volume was clean. The verifying file data (Step 4 of 5) took about 1 hour. The hardrive has 28.7 GB of free space left. About 5 weeks ago, I hooked up a new scanner and printer. I unistalled the scanner. The old printer is still installed. I installed a Hauppage Video Capture card about 2 weeks ago along with PVR software, the card and software have been uninstalled. BSOD's really picked up in frequency a few days ago and Windows has gotten a lot slower over that period as well. I really can't work in regular windows now so I boot to Safe mode w/ networking. I tried using the XP cd to run a Repair, BSOD. I tried entering setup using the XP CD to try to reinstall windows, BSOD. I know I forgot something..... minidumps are attached.....I need a beer! Thanks!
