CPU wont start?!?!

[jagsrocknfl]

Hey guys i have a new DFI motherboard with an P4 3.0Ghz H/T and a Geforce 6600 video card and 160gb HD.. When I boot it shows the video card name ect.. then a pentium 4 logo shows up then my CPU restarts and does it over and over! Then I tried switching the little cover to clear the CMOS and now NOTHING shows up on the screen!! someone please help..

Thanks!

What psu?

Can you run memtest overnite - that would most likely rule out one cause.
