I have an older custom built system with XP that crashes like clockwork approximately every 3 months. I play some games, use the internet and email and do some basic Office Apps and MS Money. That's it. I run Norton, Spysweeper, Adaware, and Spywareblaster all the time. As well as CCleaner. I used to run Spybot but it doesn't play well with Norton anymore. System is a P4 3.2Ghz, Asus mobo, 2Gig of Ram, MSI 6800 Ultra, 2 Lite On Optical drives, Thermaltake 680W PSU, Western Digital 250gig HD. The PSU, HD and video card are all upgrades from the originals. I never OC. Tomorrow I will probably take it to my friend who owns a comp. shop and he will back up my drive and then do a clean install of XP with all Service Packs and current drivers. He does this every three months it seems but it doesn't solve my issue of a crash every 3 to 4 months. Any ideas? Thanks for any and all help. Am seriously thinking of chucking this bad boy next year for something more reliable.
