No- POST question

[StNolly]

I have the gigabyte 990fx and a fx 8150.
I belive that one of these is bad but not sure which it is. I turn on the computer but don't POST, all lights and fans turn on, my keyboard lights up as-well but do not get video, this started to happen after trying to overclock my 8150 to 4.5ghz, I had done it before but this time it messed something up.

What I have tryed:

Replacing the Cmos battery
RAM Slot swapping
Starting with just mobo, cpu, psu

the psu i have is the OCZ 700w modular and if it is relevant i have the evga 670 ftw.
Not quite sure what to do next on what to order for new parts, i am thinking it is the processor though has had somthing happen to it when i OC'd it.

Let me know what you all think of it, thanks for the help

Hi,

Does the computer beep when you tale out the memory ?

If not your cpu/mobo or psu has problems.

If they are under warranty you might be able to RMA if you don't tell they where overclocked

There are no beeps with or without the RAM, I don't think my mono has a beeper ( don't know the terminology) I don't think it's my PSU though, just because literally everything turns on, GPU, H80i lights & fans the whole works does power on

make sure when you clear your cmos you pull power from the wall first and let the mb drain or the cmos wont clear.

So pull power then take batterie out like 5 min after, put back in, the plug power in?

The way I have done it is unplug, turn power on ( so it drains what is left) turn off, the take batterie out, while it's out turn it on for 60 sec the turn off and put batterie back in.
