Hi all, Was wondering if somebody(s) would be kind enough to help diagnose a problem I have with a new system build, which is as follows: Core 2 Duo E6400 x 2GB DDR2 667mhz BFG 8800GTS DDR3 320MB Arctic 550W Modular PSU x 1 Deskstar 250GB SATA II Asus P5N-E SLI mobo So problem being, the build will not post to Bios. I press the power button, everything spins up, CPU HS, GPU HS, Case lights, basically everything appears to have power running through it. However, the screen remains blank. I receive zero beeps from the Motherboard on boot, but the green LED power light is on, indicating ther eis power to the board. I've checked all the power connections, everything is connected as it should be. I've now even pulled individual parts out and tried different combo's just to see if I receive any beeps. Really at a loss as to the problem. The PSU is about 8 months old and was pulled from previous system and I can confirm works fine as I plugged it back into previous PC after the above. At the moment, I'm inclined to think the Motherboard is a DOA and needs sending back. Can anyone hear shed some light on my problem before I have to resort to the above line. Cheers.
