Hi guys, well heres the problem, this drives me nuts!

so computer was working fine for 3 years now playing games and all...

2 days ago when i woke up and switched my pc on, it wont power on. All it would do is all my 4 front/side/back fans would spin and light up with the blue leds for half a second and then power off. no beeps or nothing. Also I could not power back again for that half a second without unplogging the power cord and putting it back in. So I started unlogging pretty much everything from ram, hdds, dvdroms, video cards, cmos battery.. NOTHING WORKS!

Fast forward. I went to get a snack and something to drink, and figured id try my old video card(7800gtx) see if it would work, at first it didnt change anything but after a couple of trys it did! (yey computer was on for the rest of the day) So I concluded that my 8800gts was dead. Went on newegg ordered a new one(still en route), no big deal... So after that I wanted to make sure that my 8800gts was really dead and ship it back to manifacture BUT IT WASNT LOL. Plugd it back in and it worked for the rest for the night and day...

Now I woke up today and niether my 7800gtx or 8800gts make a difference, pc wont turn on(same 1/2 sec blink) im raging. please help me!

pc specs:
Gigabyte s-series mobo
Intel q9700 cpu
4gb of ram
600w aurora 2 psu
2 diff video cards (both fully functional)
8800gts oc 320
old 7800gtx 256
