New PC build does not power up
Posted on 2008-10-04
I have just attempted my first PC build.
All components are new and reasonably high spec.
CPU - Intel Core 2 Quad Q9550
MOTHERBOARD - Gigabyte GA-EP45-DS4
RAM - 8gb (4x 2gb) G.Skill PQ Series PC-6400 DDR2
GRAPHICS CARD - Palit GeForce 9800 GT
POWER SUPPLY - Tagan TG-800-U33 Force II v2 800watt
HARD DRIVE #1 - Seagate Barracuda 750gb w/32mb cache
HARD DRIVE #2 - Seagate Barracuda 500gb w/32mb cache
CPU Cooler: Arctic Cooling Freezer 7 Pro Skt 775 CPU Cooler PWM
I have connected all components, but when I switched on the power for the first time there was no response at all.
I have tried a different power cable, and also another power unit taken from an old PC. Same result.
I have checked and double checked that I have plugged the power switch cable from the front panel in the right terminal on the motherboard.
I have tried pressing the power button on the motherboard.
I cannot think of what to do next.
Does anyone have any suggestions for troubleshooting procedures that might help?
