PC Power Issues

I'm sorry if this is the wrong section but I'm having issues with my desktop.

About two months ago I awoke one day and tried turning on my desktop only to have it not even do anything when I pressed the power button.

To test teh problem I did the following things:

-Pressed the powerswitch on the PSU, still didn't happen
-Tried unplugging the power cable from the surge protector into the wall outlet directly still the PC wouldn't turn on.
-Tried testing the PSU on a different wall socket and again nothing happend


So after those I contacted OCZ the manufacture of my PSU and got a replacement that came in a couple of weeks ago but I've been pretty busy lately so I finally got around to installing the new PSU which was brand new in the box the other night after installing it yeah the same thing happend again the computer wouldn't turn on by pressing the power button on the front of the case.

The next day I took my computer over to my brother in laws who is building a new PC and asked him to take a look because I thought maybe I might have installed it wrong, I asked him to test his new PSU in it since he won't be building the new computer till next week sometime if he couldn't get my replacement to work. He did do this and his PSU wouldn't work in my computer either.

So my question is what could be the cause on why the computer won't turn on? I highly doubt both my replacement PSU and his brand new PSU are DOA.

I'd like to get my computer back up and running ASAP because I have important documents on there that I need to access to.

List your full system specs, it makes it easier for us to trouble shoot.

Have to tried disconnecting the case power switch from the motherboard and shorting the two pins it connected with a screw driver? That will test to see if its the switch.

Use the method shown in the video to test and make sure your PSU isnt DOA

If neither of those work, go through our full boot checklist, perform each step. It fixes or identifies most issues

Oops I forgot to add my RAM which is 4GB (1GB x 4) of G.Skill 800 DDR2

Also I did the paper clip thing in the video posted and the powersupply worked so I can assume it's my motherboard correct?

How would I use a screw driver to turn on the computer? Just curious.

I'm sure that the power button on the front of the case isn't broken I don't press it very hard as for replacing the motherboard it's still under warranty so I'd just get it RMAed from Gigabyte.

Okay well I'll test that out tomorrow since I have the computer taken apart right now and if it doesn't switch on then I'll RMA the old motherboard via Gigabyte.

Thanks for the help.
