Can someone please help…. This is what I have since Dec 2004 Intel P4-550 3.4GHz LGA775 with Thermaltake Cooling System CL-P0092 ASUS P5GD2 Deluxe Intel 915P Maxtor 80GB S-ATA KingMax 2x256MB DDR II XFX GeForce 6600GT 128MB Everything running smooth until recently, it crashed very often while I'm playing game. Then I decided to run a harddisk check-disk, it froze. I had tried 3 times and same thing happened. So, I reformatted the harddisk and reinstalled WinXp. During the process, the blue error screen came out and mentioned something "critical error has detected, the installation process has to terminate to prevent damage to the system" It also suggested to check your BIOS, …so on. I have no idea what to do. I kept trying and same blue screen came out. Also, sometimes it mentioned something like missing files during the initial winxp setup. Can anyone please give me some directions. Thanks in advanced..
