Intro: I just built a very budget gaming system. Vista 32bit, AMD 7850 Kuma, AMD HD 4670 Graphics, 4 gigs Wintec ram, 7200.12 Seagate 500 gig HD, and (most importantly I believe) an Asus M3A76-CM based on the 760g/sb710 chipset. Also, the Mobo was an open box (which could spell disaster). Currently Oc'ed to 3.2Ghz 40 min prime95 stable. All of the latest drivers have been installed, as well as the latest Bios from asus.
Problem: I am having shut down issues. When I select restart from vista, the computer reboots no problem. When I select shut down though, vista shuts down and the system seemingly powers off except the num-lock light remains lit on my keyboard (ps2). The problem occurs when I try to power it back on after shutdown. I press my power button and the computer turns on (fans whirl, hd spins, etc) but no post, no beeps no nothings. the screen just stays black. When it is in that state, I can press the reset button and the computer will power on normally, posts and boots just fine. I have a similar problem when I put the computer into sleep mode, so I suspect they are related. Also, if I shut down from vista, and then flip the switch on my power supply (cut off power for a short amount of time) and then flip it back, note that when I flip the switch to restore power to my computer the num-lock key does not turn back on) I can power the computer on just fine.
Solution: I am totally stumped. I have messed with every power related option in bios to no avail. I've built computers before and I've never come across this. I'm suspecting it might be a fault of the motherboard (it was open box), but I can't verify as I don't have another motherboard to test with. ANY ideas will be helpful. Thanks in advance.
