Hey, new to the site, so I'm not REALLY sure if this sort of problem has been addressed.

I just built a new computer, built an AMD based one before with crossfire, and it worked fine. This time, I built a Intel based computer with SLI. The problem that I'm having is that when I turn it on, it gets power, but none of the CD drives seem to be getting any power, nor the monitor and keyboard/mouse. You can hear the hard drive come on, but it just kinda sits there after you hear it the FIRST time, and I'm not getting that 'beep' you get before the computer enters into the BIOS. I checked the jumpers and made sure EVERYTHING was securely connected, but I'm now at a dead end.

here are some of the components of the computer

motherboard - ASUS P5N32-E SLI LGA 775 NVIDIA nForce 680i SLI ATX Intel Motherboard

CPU - Intel CORE 2 Quad Q6600 Kentsfield 2.4GHz LGA 775 Processor

RAM - G.SKILL 2GB 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400)

Power supply - Powertek PowerTek770W ATX 12V 2.2 / EPS 12V 770W

Graphics card - EVGA 640-P2-N821-AR GeForce 8800GTS 640MB GDDR3 PCI Express x16 HDCP (x2)

...almost tempted to take this thing to Best Buy and have them get it running. Any thoughts would be appreciated.Pull all the components from the case and do a bench test...
Hook up only the following:
PSU
CPU
1 stick of RAM
Monitor
Keyboard and mouse
Vid Card.

Make note of any beep codes. If it posts properly continue adding one component at a time til you find the culprit.

p.s. @ other questions : Did you remember to USE thermal compound ? ?
Did you use the MBoard standoffs when assembling ? ?
