Okay, this all started new yrs eve. I decided I wanted to play some Doom 3 and went to fire it up and my system locked. I rebooted and it stopped after cpu detection (no memory post). I rebooted a few times with same results and called it a night. In the morning I cleared the cmos and got it up and going. I did ok browsing the net but locked up in any games. I decided it was about time for a fresh window install and wrote zeros to the disk and started a new install. It seemed to take forever but eventually went. I started it today and went to install my nforce drivers and it just restarted and and I havent been able to log into windows since. I tried safe mode and a few other modes and still nothing (just a black screen with a blinking line in upper left corner. I have tried running memtest from a floppy and did that for 7.5 hours with no errors. My cpu temp and voltages all look good (according to bios anyways) temp is 45c and voltages were all slighly higher than spec. I ran seagate seatools and passed all the physical tests but got a file structure error. It said : "Critical errors in the index and metadata" whatever that means Any suggestions or ideas would be much appreciated (or else I gotta take it to a shop) :-( My new X-850 XT vid card comes tommorow and I really wanna get this workin ;-) Thanks
