I would really appreciate some help on this one. I recently bought an Asrock 960gm u3s3 motherboard and paired it with a Phenom II X6 1100T, hooked up all the cables from the PSU, installed all of the case stand-offs, and connected the front panel headers in the correct places, but when I press the power button, nothing happens. Nothing at all. The PSU I have was working just 30 minutes before this. Can anyone point anything I may have forgotten, or possibly done wrong?

Did you installed the front panel headers correctly? I mean, did you checked out your user manual and check if there any cable missing, broken or burned in your case? also, did you conected the 4+4 cpu cable and the 24pin as it should? Also, have you tried move your motherboard a bit with your fingers?

There are chances that you may be a short that avoids your PC to turn on, most case standoffs tend to make little shorts that prevent new builds to turn on... Taking out the motherboard, sit it on it's box and conect everything, then turn it on will give you a good idea to see if theres any electricity fails or shorts in your case.

Ok so I took the motherboard out and placed it on the piece of foam it came with, took the PSU out, leaving only the CPU and RAM connected. I connected to 24 pin power connector and the 4 pin CPU connector and nothing happened. I then tried the same thing with a different PSU and the CPU fan started spinning. There were no beeps or anything, just the fan spinning. So that means my PSU is bad right? But how could it be? It was working fine literally minutes before I took it out of another build and connected it to this one.
