I have asrock 945GCM-S.. there is no display... no beep.. i tried some basic technique in troubleshooting.. like taking off the RAM, the HDD, Optical Disk, reseating the jumper of CMOS.. removing the cmos battery...pwer supply is ok...but still their is no display... and no beep so i dont know what is realy the problem. keyboard leds doesnt light also... what should i do?

First of all, check if there are any inflated capacitors, if there is even one- ditch MBO, other capacitors will soon follow. If no inflated capacitors proceed with these diagnostic steps: 1/ disconnect all peripherials (DVD, HDD, card reader...), leave only MBO, PSU and RAM (and CPU of course); if nothing happens 2/remove CMOS battery (CR2032) for 20-30 sec with power cord disconected from computer, that will reset BIOS; 3/ take out RAM sticks, then, if you have more than one stick, try with each stick separately (it might be faulty RAM); 4/power on MBO without any RAM-if speaker is present it should give BEEP signals; 5/ try with different PSU, many power supplies are faulty even when they do give power to MBO.
If nothing of above does not help than you have faulty MBO, because CPUs are so rare to fail that in my 10 years of experience in PC service I had 3-4 fried CPU-s, and even that was because costumer tried to clean PC, removed CPU cooler and than incorrectly placed it back or didn't put thermal paste afterwards.

i am swicth on my pc but no display and auomatically off he pc

Its very possible that it is a RAM issue, try running with only one RAM stick, reseating the RAM and identifying if any is faulty.

Hi
beep error is a problem in hardware. most likely it is a problem in the ram or the display card. perikasa and do the tests on two devices, better you use a 100% working hardware to perform troubleshooting.

regards

sounds like no bios
or bad motherboard all together

Hi,
If do not hear any beep then it means that the mother board is dead you can try clear the BIOS by removing the battery of the mother board for 5 mins or by shorting the jumper for clearing the BIOS if that didn't help then you have to repair the board or replace it.

No beep or sound means Motherboard Defective, aside from Processors is OK, Memory is OK, and the rest!
Buy a new one not as the same Motherboard you use. ASROCK Motherboard are have a a problem when high temperature occur.

If i am helpful to you, please rate me.
Thank you.

The exact fault code indicates RAM or a problem accessing the RAM.
Check that you are using recommended/Approved RAM as ASUS and ASROCK (the budget arm of ASUS) are notoriously fussy with RAM.
If it all checks out then your northbridge could be dead and it will probably be scrap.

its your motherboard problem if its have a warranty then send it to the asrock service centre if not then repair it

While booting BOIS goes for POST check for detecting the all the hardware .

Disconnect all the connection to DVD, HDD, FDD from MOBO.
Rmove all RAM and start the ssytem from testing RAM Serviceability. If you listened a long intermittent beep place a single pices of RAM in MOBO ( repeat test with other RAM also).

Other wise your video card is unserviceable, if you have any addon plugins like NVIDA graphics card you can check
