Blue Screen of Death on new computer [Dump data]

Best thing at this stage probably is to do a Windows XP Repair install, hopefully you have your XP installation disk.

Boot from the WinXP CD (you may have to change a setting in your BIOS that allows you to boot from the CD). Do not choose the option to repair an XP installation using Recovery Console when prompted, choose the option to To set up Windows XP now press ENTER.

After more files have been copied, you'll get another selection screen where you should select the current XP installation, & the option To Repair the selected Windows XP installation, press R.
