Hi guys. This is a new rig that I just received today.

GIGABYTE GA-MA790X-UD4P AM3/AM2+/AM2 AMD 790X ATX AMD Motherboard - Retail

CORSAIR CMPSU-650TX 650W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS Certified Active PFC Compatible with Core i7 ... - Retail

AMD Phenom II X3 720 2.8GHz Socket AM3 95W Triple-Core Black Processor Model HDZ720WFGIBOX - Retail

SAPPHIRE 100259L Radeon HD 4870 512MB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card - Retail

G.SKILL PI Black 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model F2-6400CL4D-4GBPI-B - Retail


Problem is, I get no start up beep from my motherboard and also I am getting no post screen on my monitor. I have gone through the ""New build won't boot" checklist sticky post and currently testing in the breadboarding way. I am guessing something is faulty and I think it's the Motherboard, but I am not sure. Which piece would i have to RMA ? motherboard? psu?

Are you sure you PSU is on? LOL

Did you load windows yet? Make sure everything is plugged in right?

Yes. The fans on the graphic card and the CPU all run, I see the lights on the graphic card too. And no, i havn't yet connected a hard drive yet since I'm still in the breadboarding stage. Can't install windows yet if i can't see anything on the screen or go into bios to see what's up.

Plug the hard drive in then...without loading windows...but your board may still need to see it....

Make sure your RAM is sitting nice and tight...

I tried plugging in the hard drive, and nothing is still coming up. My monitor is blinking.

What is weird though, I plugged out the 8pin cpu power cable and plugged in a 4pin cpu power cable instead into it. The Screen actually came up with the post. I got all excited and restarted the motherboard so that I can go into the bios, but then ...... blank screen. Monitor is still blinking as if it never saw anything. Could there be anything that could cause this?

Update: I placed my video card into the PCIE x 8 slot instead of the PCIE x16 slot and it booted up fine. I am also using a 4pin instead of a 8pin for the cpu power. Is this because of a defect in the PCIE x 16slot or do I have to enable something?

And if it does end up the x16 slot is defected, would it effect my game performance a lot by just keeping it in the PCIE x 8 slot?
