so what your saying is i need a new mobo?Just a bit of info on a problem I had in the fall.
I took in a PC from a friend at work that I was going to try to get working and salvage it. It would post, but that's it. It sat on the post screen and there was nothing else.
Keyboard showed that it had power, but it wouldn't follow any commands at all. Got a motherboard/cpu/ram combo. Using the original power supply and a new HDD, it worked just fine.
Sidenote: even though the keyboard showed power, I couldn't enter the bios, as if the USB controllers were toast (tried in all 6 usb ports, didn't bother trying to find a ps/2 keyboard.) Power Supply was fine also.
Well, going by what you say, i'm not so positive, but in my opinion, it's leaning that way.
Does your POST screen show that it is detecting the ram/ hard drives?
Mine seemed to take about 2-3 minutes before it detected anything at all, which is wayyy too long and a sign that something was shot.
I just wanted to share the problem I had, which turned out being the motherboard. I'm guessing since it wouldn't go past the POST screen on mine, and the USB wouldn't actually work, that the MB was shot since it wouldn't do anything even when hooked up the new HDD to it( did that before buying the combo, just in case). Also, nothing happened when I had a disc in the dvd drive.It was as if the whole MB was toast and wouldn't see anything that was connected to it.
I would still go through every possibility of combinations to see if anything changes before assuming it's the MB. Mine was just obvious once I had the new HDD.

Still learning my way inside the tower lol but hopefully i learn from my mistakes to better my future and next time il'l know exactly what to do. Again sorry i didn't mention this earlier totally blew away from my mind till right now when you mentioned it. But ye if with the new psu i have coming in the mail doesn't fix it then il'l probably take it to a shop since i'm a bit inexperienced when it comes to the mobo. Barely started getting into learning about the hardware last year since i been taking a computer repair tech class in my highschool. I'm learning alot though from the class and from what i see here in sevenforums though. I see it as a learning experience from my mistakes, still upset i messed it up like that though :/ But ye i was planing to upgrade my psu this month so that's why i took this one out to see if i could get the old pc to turn on with the psu but then i saw it needed a microatx plug which is what i should of checked in the first place before removing it. Anyways new corsair psu coming will try to see if it works with that one and if not possibly take it to a shop and see what they can do for me like to make it work or suggest me a mobo and have them put it for me since i'm kind of scared i might mess up it up again.
