Hi, I have a problem with my asus P8B75-M LE mobo.

I don't have a POST and nothing happens when shorting the start pins (no fan movement or sound from the speaker) although the standby led on the motherboard lights up when I turn on the power supply.
the motherboard is out of the case and the only things connected are the memory, the cpu(intel celeron G460), the power supply (I tried 2 ones(250w and brandnew 300w) and the speaker.

I looked on the internet and I found lots of information but nothing works. I tried to reset the CMOS by changing the jumper on the motherboard but nothing changed. It wasn't used for a couple of months and was just installed inside a case without powering it up for a while.

Does anyone think of a solution or should something be faulty?
