Alright, so I've tried to re-seat the CPU and it was in correctly to start with. I was skeptical about applying new paste, but I did not have any around as of now.
Everything is connected fine.
I am going to post it again without the system memory to see if I hear any beeping. I didn't hear anything at all whatsoever when I hit the power switch button on the motherboard to try and turn it on.
My video card has been used on a separate system a few weeks ago and is fine. So I've kind of narrowed it down to the power supply or the motherboard itself being the problem. though I am still going to try to post it without the RAM right now.
EDIT: Alright so again, I've had everything connected. The PSU's main connector and the two 4 pin CPU1/CPU2 ones in. that blue light comes on again indicating that the power is on. the PSU gives enough power to turn that blue light on. Then when I hit the power switch to turn everything on, nothing turns on at all. Only a yellow light does almost indicating that it's on standby? or some sort. The speakers are hooked up to the mobo just in case if I could hear any kind of beep, but nope. nothing is heard. Same result with 1 stick of RAM. same result with NO sticks of RAM in. all attempts with the GPU in. =/ I am going to try the system later on today with a different power supply so I will again update this later again today.
