my friends CPU is hitting 50% on idle?? Windows Problems....

Well my friend has a micro ATX Motherboard becaus it was cheap. he had a single core but i bought him a cheap dual core becaus it was allways using 50% of his CPU for no reason.

1 reason is this. he had windows XP SP2 but when he upgrades to service pack 3 it uses 50% of the CPU even idle.

I have installed fresh a windows XP on his pc about 10 times. and each time iv done it when i upgrade to service pack 3 it dose the same thing.

and now i install windows vista on his PC and it dose the same thing.

has this happened to anyone? is there a fix? its getting really annoying becaus my friend is stuck on windows XP SP2 and is not able to update at all. when he dose the problem returns.

i think i heard something about AMD cpu's havent trouble with sp3

have you tried to find what ever is doing it? by like going ctl + alt + del and looking at processes
