PC Reboots Automatically
 

I recently installed an updated copy of McAfee which contains Virus Scan and Firewall. When I open Limewire it loads old searchs, then starts downloading files but after approximately 2 minutes the PC automatically reboots for no reason. I have tried uninstalling/installing McAfee and also shutting down VirusScan/Firewall, but I continue to have the problem. Everything on the PC functions correctly except Limewire. I am using Limewire Pro 4.10 and Windows 98SE. Please Help!!!!!
