Having trouble with my PC which insists on running at 100% most of the time, even when at idle with no apps running it jumps between 10 & 25% - normal system should run @ 1 or 2 %. I've re-installed XP Pro on the PC a couple of times now, as soon as its installed though i get the same problem as above. Ive also completely erased the drive using Diskscrubber before the last install just in case anything was left behind. The PC is a little old with a 500mhz AMD proc, 184mb & a 10GB HD although i also have a similar spec machine (with just 128mb) which runs just fine (even with XP & Win 98 dual boot!) which makes me suspect that its not just the age of the PC. Anyone have any suggestions? Dellboy Title Edited - Please follow new posting rules from now on. --Zxian
