i have a problem with this PC where upon launching of a program, the CPU Usage shoots up to 100% eventhough it's not a resource demanding program.. it's a newly installed WinXP SP2 with no internet connection. other specs: Pentium 3 400MHz, 640MB RAM, Geforce4 MX440, etc..
i've tried scanning for spyware & viruses (eventhough the OS is newly installed), defragmented the hard-drive, tried changing the drivers for the graphic card. now, i'm thinking of hooking it up to the internet & run the windows update but before that, i thought i'd make a post here.. so does anyone knows why this happens? also attached some screenshots to explain this crazy thing..
