Please help troubleshooting new kit

Hi

Just got the following in the post:

• Motherboard: Gigabyte GA-MA790X-UD4
• CPU: Athlon 64 X2 5200+ 2.7 Ghz
• Cooler: Xigmatek HDT-D1284 Heatpipe Cooler
• Memory: Mushkin XP2-8500 2x2GB DDR2-1066
• Graphics: Gainward GTS-250 (G92b) 1GB DDR3

I connected them to a Corsair 450W PSU

When I power the thing up, I noticed that the CPU fan was not spinning so immediately powered off, checked the cabling and tried again. Still not spinning. I then swapped out the Xigmatek for the stock cooler and powered on. The stock cooling fan spins up fine, but there are no beeps and nothing on the screen.

Do I have a dead mobo? What further troubleshooting steps can you recommend?

Thanks!

have you added all power connecters to Mobo including 24pin and 4 pin all HDD's powered and have you got the power in for the card? also did you put the little metal risers on the case so that the mobo wouldnt short also check card is seated properly and as for the fans i am unsure on that but check it ius all connected properly.

Thanks - my problem was that I hadn't plugged in the ATX_12V_2X4 power. Never seen that before on a motherboard - all working now though...
