Newly built PC wont POST.. PLEASE HELP!

[mobusta1]

Sorry about the double post I meant to post it here but it got posted in the Intel forum. If a mod can delete the intel one that be great.

Here is what I bought a few days ago and installed it today

SAPPHIRE 100243L Radeon HD 4870 512MB 256-bit GDDR5 PCI Express 2.0 x16

1 GIGABYTE GA-EP43-DS3L LGA 775 Intel P43 ATX Intel Motherboard - Retail

1 G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1000 (PC2 8000) Dual Channel Kit Desktop Memory Model F2-8000CL5D-4GBPQ

1 Western Digital Caviar SE16 WD6400AAKS 640GB 7200 RPM SATA 3.0Gb/s Hard Drive - OEM

1 Antec Nine Hundred Black Steel ATX Mid Tower Computer Case -

1 Intel Core 2 Duo E8400 Wolfdale 3.0GHz LGA 775 65W Dual-Core Processor

1 XIGMATEK ACK-I7751 Retention Bracket

1 XIGMATEK HDT-S1283 120mm Rifle CPU Cooler - Retail

1 CORSAIR CMPSU-750TX 750W ATX12V / EPS12V Power Supply - Retail

This is the first time I've ever built a computer myself. It turns on fine so I dont think its the PSU, the LEDS on the MB light also. I've taken out one stick of ram than swapped it and even took out both sticks of ram but the PC still wont make a beep noise when I turn it on. I have no clue what to do. Anyone please save me i've spent almost 8 hrs working on this and now it wont even work. I feel like crying

It could be one of a dozen or more things.


Is your Ram properly set?
Did you connect all the wires in the correct spot.
DO you have your VGA/DVI cable pluged in the back?

Etc.... its hard to say.

Try some of the troubleshooting steps listed in the GenHard FAQ. You may also want to take the mother board out of the case and look for any stray screw or other things (inside the case) that may be shorting the motherboard.
