so I had this mobo and cpu sitting in a static guard bag for about 2 months and my friend was interested in buying it....

I hook it up properly and check all the connections and when i turn on the computer nothing happens with the computer besides all the components powering up and all the fans spinning

I don't hear any post and nothing shows up on the screen

any one have any ideas?

this mobo and cpu combo was working before i put it in the static guard bag

Nice to know what the board and other hardware is...??? Are you sure you plugged in the other 4 pin power connector ?

it's an :
Asus P5W-DH Deluxe
core 2 duo E6600
500 watt PSU
4 GB corsair ram
120GB WD Caviar SE
7900GT

and i'm pretty sure i put the 4 pin power connector in
it put it in and it snapped in and i could push it any further

i've also tried this mobo with another psu

Pull all connections and plug them back in. SATA/Power/etc. Pull the hardware and re-seat. Ram/Video...Use only 1 stick of memory. Move it around if it doesn't work in one slot. Plug the HD in a different SATA connector on the mobo. You didn't say how long it ran for. If it started and shut down could be the processor isn't getting cooled right.

From the few details, it sounds like the 4/8 pin CPU power.

^Agree. Sounds like you either did not plug it in, or you are trying to force the wrong plug into the socket. There is only 1 plug that will work, and it is keyed so it only fits 1 way, and it should simply slide right in and snap into place.

Check back after you've performed EVERY step in the checklist. "Pretty much" doesn't cut it when trying to troubleshoot a booting problem. If you get through every step in the main checklist, don't forget to perform the breadboarding step at the bottom.

Unmount the mobo. Place it on a piece of cardboard next to the case. Hook up the hard drive, PSU, CPU, video card, mobo speaker, power switch, and 1 stick of RAM. Leave everything else unplugged.

Try booting with only these parts.

Did this and nothing happened :( 

btw, could a dead battery for the CMOS cause a mobo to not start up?

BING GO... You found your issue!!

Since your motherboard had been sitting for a few months, so your battery went dead. This normal isn't an issue on new motherboards, so it isn't check as an issue very often. Since your MOBO has been sitting around, it is a very likely the issue. Your motherboard won't work with a dead battery.
