I'm in the process of reading the help posts here and on the web, but it's all Greek to me, so any help would be much appreciated. Keep getting the BSOD, have to wipe hard drive, re-install XP Service Pack 2, and my computer runs ok for anywhere from a few hours to a week or so. It's been crashing about every weekend. My computer: Dell XPS Gen 2 120GB HD 3 Gig Ram (2 512 original ram, and I added 2 kingston 1gb ram about a year ago) Run basic programs like IE7/8, Firefox 3, adobe reader, office, etc. But crash happens when not much installed, so i doubt it's software. From what I've heard, it might be memory, so I removed the original memory, and kept the 2 gigs of Kingston ram in there, and it still happened. I have to go home and reinstall OS tonight and then take out kingston memory and put back in the original Dell memory and see if it crashes again. If it doesn't crash in a few weeks I'll assume it was the Kingston memory, but if it does, I'm at a loss and will assume it might be hard drive or video card?? I've reinstalled the OS like 5 times in the last month. All the programs I run, I've been using for years with no problem. Computer is 4 years old, used pretty heavily. Dust bustered the inside of all dust, but will try again with compressed air. I've run diagnostics on the HD and memory several times (from the Dell diagnostics disc) and they always come up clean (if that's worth anything). The latest error codes are : Stop 0x0000007E (0xC0000005; 0x80567B0D; 0xf789E0A0; 0xF789DD9C) Like I said, I'll try to learn what I can here at work, but my time is limited for research and computer doesn't work very well at home obviously, so any/all help is greatly appreciated. Thanks!
