So I have built my new computer I have worked on for awhile and coming here for help to fix the bugs because this is my source of knowledge. My computer: MB: Abit ix38 quad gt 775 Video: EVGA 512-P3-n841-a3 8800 GTS CPU: c2d 6750 2.6ghz Mem: G. Skill 2 1 gig sticks f2-6400phu2-2gbhz Timings 4-4-4-12 Power: ocz|OCZ700gxssli 700w rt HD: WD500g sata2 300mb/s Case: aerocool Cooling: watercooled CPU, case cooling is excellent. OS: Windows xp 32 bit Well the problem I am having is my first build, I got it all running perfectly and it started crashing at night when I was asleep, woke up one morning and it had a windows error and needed the windows disk to repair the system. Did this and got the computer up and running again, but could not install the windows updates this time around, was able to download but it just said failed to install. So I ran a diskcheck to try to fix anything. Two days later it started crashing again while playing games under small load (25% or so). Then one night while playing, get a bsod, error was something about a nv4_disp.dll, googled that and found out bad video card drivers. So I updated the drivers and got past this error. 20 minutes later surfing the web, computer crashes. I reboot and after doing the normal bios stuff, it goes to the windows loadup screen and then blacks out on me, where the windo logo would normally be, is a black screen and my computer never gets past this. So I talk to a few people and they say HD, so I go and replace my HD with a new one. Reinstall everything normally, update windows and get everything running like it should. Go to install World of Warcraft and it freezes on disk one, try again and later in game it freezes, get an error of corrupt data and to run a scandisk. Run it and it finds stuff on stage 1 2 and 3, but not 4 or 5. Go to install WoW again and freeze again, after 4 trys I am able to get to disk 2 on installing WoW, but it freezes there. Tried 2 different dvd drives to install, no luck. Checked all my cables and no luck, also tried a different set of WoW disks, once again no luck. I am at a loss. Any clue what the problem could be? Memory? MB? Settings? Any help is greatly appriciated guys as I am out of my mind on this one.
