WinXP Pro P2P Problem

[raw1982]

Hi im using Winmx and Direct connect to share a download files, i have recently just formatted my computer with a clean install of XP Pro, my problem is that if i seem to leave my computer running when i go to bed by the time i wake up it seems that my computer had restarted itself for no reason. i get a message saying "would you like to send this report to microsoft" anyone have any ideas, im using zone alarm, norton anti virus 2002, 80gig IBM Deskstar, thought it could be these affecting it?

I dunno how well Winmx handles long uptimes but Direct Connect is most likely the cause of it. The program isnt that good and after you leave it on for a while it will start to use 100% cpu and then crash..
