Reveille. Do you still remember what you did during the five
minutes of use? It would be helpful if you can pinpoint the
"trigger" of your BSOD.
Since your post is too vague for me to completely understand your
situation, I can only give you general advice.
1) Download a Memory Diagnostic, and test your system memories. If
there are errors, it means it's time to change the memory.

2) Download your Hard Drive diagnostic software. If there are
errors, change your hard drive.
My Computer -> Properties -> System Properties -> Device
Manager -> Disk Drive -> Your Hard Drive -> Update
Driver
None of the above?
3) Your processor might be the one that is overheated.
Check that the fans are running, and reboot your computer. Press
DEL repeatedly before logon to enter the BIOS screen. Leave your
computer running for approximately one to one and a half hours. If
the Windows crashed, your processor is definitely overheated. Buy a
new processor.
4) Unplug everything from your computer, as in mouse, keyboard,
drives, cards, memories, etc. Reboot your computer. If it can work,
then plug each one back one by one to see which "triggered" the
failure.
5) Reinstall XP again.
