If you have a cd key then I would just re0nstall and start from scratch.
If the other computer shuts down I would check for a hardware issue.
Possible overheating or dust.
Just my 2 cents.
Anyway since this is not a mlaware issue I will close this thread.
If you should need asssistance there is another forum Xp Forum
that will be able to assisst you.
Satrt a thread there and they will be able to help.
Since this issue appears to be resolved ... this Topic has been closed. Glad we could help.
