Skormthemage · Oct 17, 2013

Hi I have a GIGABYTE GA-Z87X-OC Force LGA 1150 Intel Z87 and a 4770k, also a Cooler Master Silent Pro Gold - 1200W Power Supply with 80 PLUS Gold Certification , when I power it on the screen is blank and then the motherboard immediately turns back off and try's to power up again continuously , I've done some overclocking before on this processor to 4.8 ghz then sent back the chassis I was using I stored the processor in a anti static bag in a box I don't know if its my processor or PSU, please help guys? if there's any more info I can supply you with please ask in resolving this issue

Could very well be a bent pin but lets not jump to conclusions. First remove the system's power.

then:

- remove bios battery
- remove ram
- Make sure that all your standoffs are good and no shorting is occurring
- Check motherboard jumpers

Once that is done put the battery back in and one stick of ram; remove any discrete video card/s

Then make sure that only one monitor is hooked up to the internal graphics adapter. No mouse, keyboard, anything.

Start the system. If no luck still try swapping the ram to other slots.

If still no go, I'm out of suggestions other than checking the cpu socket. Hopefully that fixes it but if not maybe someone else around the forums can provide additional instruction.

ill try to remove the cmos and ram, there is no internal graphics adapter that I am aware of.

Believe your mobo has a HDMI port on the back, your CPU has graphics built in

Tradesman1 :

Indeed you have intel 4000 hd built in.

a number comes on the motherboard 15? that mean anything?

thor220 · Oct 17, 2013

Skormthemage :

Yes, it's an error code. Look it up in your motherboard manual. If you don't have the manual, you can get a digital copy from your motherboard manufacturer's website. This code will tell you have is wrong with the system.

error code says pre -memory Northbridge initialization is started, it always shuts down at 15. does this mean the processor is bad?

thor220 · Oct 17, 2013

It sounds like you computer is having an issue with the ram. Did you try one stick and each slot?

Make sure that your ram is on the supported ram list for your motherboard as well.

still 15 with one stick even tried a different one

could it be the motherboards faulty? this ram worked fine on a friend who has the same board.

What is your RAM?

Remove any graphics card and anything other than the PSU, board, memory, CPU and cooler. Connect monitor direct to board. Reset cmos, then try booting. If fail to boot, I'm afraid there's a fault with one of the critical components.

When you sent back your chassis, did you take the CPU off the board? When reassembling did you apply thermal paste? Check that the cooler is seated properly.

Gskill MEM 8Gx4|GSKILL F3-1600C7Q-32GTX R, yes I did take the cpu off the board, i removed the former heat paste with rubbing alchol. and installed water extreme 2.0 on it, that was a differnt board though same model.

huilun02 · Oct 18, 2013

So you changed the board as well? Check that the processor pins are not bent and that there is no thermal paste in the processor's socket.

If nothing works perhaps you got a bad board.

Skormthemage · Oct 18, 2013

reseated everything still no go.

Thank you everyone ill send the board into gigabyte
