Hi, I bought an ASUS P5GD1-VM mobo for my new PC. When I put everything togather and pressed the power button the monitor didn't switch on. I know that a quite common problem but I just can't fugure out whats causing it. The graphics card is brand new and working. The ram is listed in the lsit of the recommended rams for this motherboard. the PSU is high quality and is fully compatible with this type of motherboards. When the power button is pressed a sugnal is sent to the monitor because the green light comes on but 2-3 seconds after this it goes on stand by again. The mobo has onboard video. I have tried removing the PCI-E card and connecting the monitor to the onboard video but still the same result. The full specs of the system are: P4 LGA775 2.8Ghz ASUS P5GD1-VM 2 x 256 Crucial DDR400 80GB Seagate hdd Winfast 6600GT Cooler Master Real Power 450W ATX 2.0 I will be gratefull for any help given. Thank you in advance.
