G'day, my gigabyte ga-m78sm-s2h does nothing more than power on. It won't post wnything, I disconnected monitor, ram and drives and it wouldn't even give any error messages. The cpu fan will sometimes stop spinning as well.Would it be the motherboard issue or the CPU that has failed? Thanks

Gigabyte has the manual for the GA-73PVM-S2H on the product support site: http://www.gigabyte.com/products/product-page.aspx?pid=2691#manual . The full manual is near the bottom of the list. The direct link to the English version of the manual is http://download1.gigabyte.us/Files/Manual/motherboard_manual_ga-73pvm-s2h_e.pdf . The Motherboard Installation Guide at the top of the list is a generic manual for all motherboards.

The front panel connections are shown on page 28 of the manual. There are two lines of pins. From left to right, the inside line of pins are the Power LED +, Power LED -, Power Switch +, Power Switch -, then the Case Speaker +, Case Speaker -. (The speaker - is next to a Case Fan connector; so there are a couple of blank spots between the speaker + and - pins.) On the line of pins at the edge of the board, again from left to right: HD LED +, HD LED -, Reset Switch -, Reset Switch + . There is no contact on the last pin in this group.

I hope this helps.

I suggest you replace the motherboard.
If you know a service center near you that can fix motherboard then bring it to them to have it check.

Just had the same problem, same board. This mb does not play well with all types of RAM. I had a single 2gb Patriot dimm and it did the exact same thing, removed the RAM and it would boot but no screen. Replaced the single dimm with 2 - 1gb dimms and it booted right up with no problem. Hope this helps.

case sounds fine, a little iffy on the power supply.

I am not sure on the beeps on what your mean. There is a short beep or a long beep or a series of beeps. Here is a website for you to help you to determine that.

It definately sounds like a heat issue.

Did you use the thermal paste to heat sink? Make sure your fans are all running. Make sure the heat sink is snapped tight to the processor.

I would suggest a system monitor to detect heat and speed of fans.

Dear friend go here your download.

if it helpfull please rate me.

Try getting into the BIOS and making sure that it is detecting the RAM and HDD and Processor. Typically this happens when theres no memory or a memory problem. If its the Hard drive it will say NTLDR missing or Hard Drive failure. When its blank.

Does the Hard drive fire up when its sitting there? Does it seem like it booting the Hard drive or does it just sit there.

Also, if you have an onboard Video and a video card, try using just the onboard video for now, sometimes the Video card can cause an issue if it doesnt have drivers and comes up blank.

Make sure the bios has the video set to PCI or AGP depending which you have intstall. Or Auto if it has it.

I have had two Gigabyte board and im using one now and have had similar issues that where caused by a ATI video card.

Good luck and let me know if you still need help.

take your RAM out from the slots and insert it again
also clear your cmos

no beeps, indicates you have faulty CPU or mainboard.

• remove all components even RAM and CPU.
• insert only CPU and Speaker (without RAM or any other componet).
• Boot and try to hear, there must be long beep for missing RAM, if not then try to re-insert the CPU or change the CPU/Mainboard.

Thanks and Good Luck
