My borther and I have built a new system with the Asus P4C800 Deluxe Motherbord, a 2.8 P4 800 FSB, with 1GB of DDR 400 RAM. The video card is a Asus Geforce 4 Ti 4800 SE at 8X. The PS is a Antec 480. With Windows XP Pro as the OS. The sound card is a old one that we pulled from my Dell 8100 when the Onbord sound was making the system crash all the time. The Problem that we are having with it right now is that. when we play games or just a random the system go blue screen and does a blue screen. We have kept the system up todate with BIOS and driver updates the probem keeps happening and we cant figure it out. The first sign of trouble was teh onbord sound but we got that one fixed now it seems that either the MB chip set drivers are messing up on us or it was the BIOS screwing up. (I just updated the BIOS and havent tested the system yet) We also know that the crashes are not a heat problem, we have 2 80mm Vantec tornados in the system and a 60mm that does close to 60CFM. with a fan controler (when you trun the fans on full power, it is loud). As of right now the system is not overclocked. if some one can help me that would be great.
