why is my motherboard bleeping?

Gigabyte Ga-h55m-ud2h desktop board - in...
March 21, 2011 at 17:56:56
Specs: Windows Vista, Intel i5 760/corsair xms3 DDR3@1600Mhz
Hi, some months ago, I bought a Gigabyte GA-H55M-UD2H MB, but lacked the neccessary funds for the other devices. Recently, I purchased the neccessary devices and assembled them. The fan works, keyboard LEDs flash once, then all of the LEDs on the MB stay illuminated and the speaker bleeps rapidly without pause for 10 seconds. Then there's a 2 second pause. PC dose nothing else.
I'm confident it's caused by a hardware conflict. Most likely the wrong memory modual(I used Corsair xms3 2x2Gb of DDR3 @ 1600Mhz with a intel i5 760 CPU-dose not support Intel gaphics) or damage to the MB it self. This perticular board, dose not come packed with a CMOS jumper. I placed one on, forgot it was there, and started the PC(for the fist time)-with it on. Please can, someone tell me, if it's possible to damage this board by leaving the CMOS jumper on during start up. Most other motherboards leave them on, but in the manual it says "place it (ON) for a few seconds if you want to clear the COMOS settings".
Help! Please!

Did you get a manual for that? The beeps would be some order usually. Like two short and one long and then repeats.

It is possible on some boards to completely damage it with the jumper left on. Again it is in the owners manual.

Beep codes mean that something is wrong, download the motherboard manual or lookup the beep codes for that brand.

Other mothrboards may have 3 pins for the clear CMOS. Yours only has two.

I think you fried the motherboard.

I have the beep codes. It dose not corispond with any of them. The manual says nothing about wht happens if I leave the jumper on.
I think I have fryed the motherboard and as it's still under warentee so I've been in touch with the manufacturer(Gigabyte), to arrange return and repair.

Looks like this ones for the bin. Will they suss what I'v done and refuse to replace it?
Can they do that even theres no warning in the manual?

If Gigabyte determines the damage was caused by YOU, they're within their rights not to honor the warranty.

"The manual says nothing about wht happens if I leave the jumper on"

You'd better have another look. From page 33 of the manual, next to the yellow warning triangle:

After clearing the CMOS values and before turning on your computer, be sure to remove the jumper cap from the jumper. Failure to do so may cause damage to the motherboard.

I did look again at the manual and you were right, it dose say exactly that. but it dose not state definately whether it will cause damage or if that voids the warrantee.
I purchased a new one, same model/specs and installed it. Only this time I followed the instructions more carefully. Now there's no POST bleeps and no LEDs flash on my monitor, mouse, or keyboard?
However, the second MB did come with an advce note, which says "unless you have a processor which enables you to use the motherboad VGA/DVI you must install a graphics card". Or words to that effect.
So I did, and now theres no POST bleeps or any sign of the mouse, keyboard or monitor working. Only the CPU fan works and all of the LEDs on the MB remain lit up and the system attempts to reboot, but after a few seconds the power cuts out and nothing for a few seconds, then it trys again, and again ect... There's no POST or bleeps. When I removed the graphics card, again no POST/bleeps? it did the same as before I tryed the graphics card?

Could it be an incompatable graphics card(PNY 9800gt) or incorrectly inserted VGA card or is it the CPU thats causing to have No POST/power to cut out?
