New computer won't boot.

[jcutner]

I'm stumped. First time posting here,

I'm upgrading my computer, so I purchased the Asus P5B mobo, E6750 and 2x1gb Corsair DDR2 800mhz Ram. I currently have a 650W Coolermaster PSU and I also tried an Antec 430W PSU.

I took out the old mobo, etc (3800 X2, A8N-SLI, 2x1gb Corsair DDR400) put in the new motherboard, put in the CPU, dropped on the HSF, put in the ram, put back the video card (keeping my 7800GT for now) Plugged in all the power cables, plugged in the case pins to the motherboard.

I plugged in the power cable to back of the PSU and switched it on from there. The green light comes on, on the mobo. When I press the power button on the front, NOTHING happens. I tried switching around the PWR SW pin so many times, and nothing at all. I even tried another PSU as well.

I'm completely lost here guys. Thanks for any help.

I have. I pulled one stick of ram, and still nothing.

this maybe stupid, but is your RAM plugged in the right slots? RAM1,2,3 and so on? Sometimes it is the simple things that mess us up.

I've been talking to some of my other friends, that work at computer shops.

I'm almost positive it has to be the motherboard, since it natively doesn't support 1333FSB unless it has a BIOS update from January, and of course I have no way of knowing that. So I packed the motherboard back up in the box, and I'm going to exchange it for a motherboard that fully supports 1333FSB tomorrow.

My other friends also purchased the E6750 chips this week, after I told them I was going to get it too, but they each got different motherboards which supported 1333FSB natively, and their's worked fine.
