I've built 4 or 5 computers in 2004 and starting this new year My cousin's computer continualy reboots and wont startup in any of the Safe Modes. So logically I try to boot. Then I reformat and try to reinstall XP pro on their comp. This is where I get my problems. The format completes in NTFS and is copying files. When it's copying files it says Setup cannot put XXXXXX.sys or some other files on to the HDD because it isn't a valid XP system image. I must have formatted and reformatted at least 7 times on this damn comp. I've tried using my friends XP pro cd's and it gives me the same error. Sometimes a blue screen with a stop error at 0x00000050 blah blah blah. The specs are: ABIT IC7-G mobo, PC3200 512 MB DDR RAM, Segate 160 GB 7200rpm HDD, Samsung RW + 2nd drive DVD, ATI RADEON 9600 XT. If someone can help me with this dilemma I'd appreciate it very much. Thanks.
