frame rates on games (669)

hi, i rebuilt my pc over a week ago, the problem i had was everything ran fine but games had very random drastic frame rate drops (single figures) they would then climb back up, i thought this was either a heat or power issue, i changed cpu, grx card psu, flashed bios all drivers up to date, i could work this out.
as i was trying to find the cause of this problem, i alt/ tabbed during the slowdown to find cpu 100% game was 20% dwm exe was 25% the rest was eset?
disabling protection i dont see this problem, as soon as i re-enable it's back? i have no other security software installed 37 running processes (on 32 bit vista!)
in browsers i put an 'x' in all my online games, i have never had this problem before and it's only ever happened on the latest version.
any ideas?
thanks
