First off; I'm building a decent PC, the specs are: Core i7 920 Gigabyte EX85 Mobo 6Gb Corsair DDR3 1Tb HDD 7.1 Surround 2x 9800 GTX 512mb 850w PSU I don't post that to brag as even so it's not my PC, but a friends who I am building it for. Here's the issue I need help with though: Everything is plugged in, it's all cool pasted and ready to go. You start up the PC and all the fans run, LEDs turn on, HDD spins, and so on yet the Monitor never comes on (it stays off with the orange light) and the mouse/keyboard never light up. I've checked the RAM, reset the CMOS, replaced the cards (took them out, inspected, and then put back in) as far as i'm aware, the PSU should be able to handle it. The cards even power up. What could be causing this? funky mobo? The monitor works for sure, tested it on the laptop earlier (though I can't get it to work now- Just sits at "no cable connected" but the laptop responds to being plugged in (extends the screen) so I think it's the laptop here, needs a restart, I'll try and see. Edit: yep, just needed a restart. So monitor works fine. Any help and suggestions would be great, thanks!
