hi,
I've just bought a new PC with Vista, and when I run games it goes down from 40+fps to about 2fps approx. every 5 seconds, then back to 40fps and the cycle goes on cry baby

. Happens on all my games, and sometimes the system slows down like that while not playing games, under load.
My system specs are:

Amd athlon x2 6000+ 3ghz dual core
2gigs ddr2 533mhz ram
geforece 8600gt pci-e
Hec 550W peak psu
asus M2N8-VMX motherboard
500gig hdd

I underlined the peak part because during the 2 weeks i've had it, i've come up with a theory that it's the 550W psu that's causing this, because it's a peak supply so i suppose it only gives out 400W sustained. My system shouldn't need that much power, surely?
Any ideas about what's wrong or anything that could help would be appreciated.
