What I meant was CPU use. Now its even worse. Changed the jumper settings and I got a CMOS Battery low error. PC is still at 100% usage and really fucked up.

Is it the battery? Would that cause the high CPU usage. It's also got the wrong time and lost two years when I formatted (thought it was in 2005)...so I guess it is the CMOS battery. Do they usually only last 18 months or something?
