I have a very old PC at my office where I work as an It assistant. when starting up it gives a beep sound. The sound goes as 3 beeps and then 9 beeps and another 9 beeps again. This Pc has a gigabyte mother board. I tried reconnecting every hardware connected to the motherboard including the RAM to no avail. pls. help

The make of the motherboard does not really help. It's the maker of the BIOS that's important to know where BIOS Beeps are concerned. Generally, 9 short beeps indicates a faulty BIOS chip, and that means the motherboard needs replacing.
thank you for your resopnse. It's great help
3-9-9 isn't a pattern I've ever heard of. Are they all short beeps or a mix of long & short? What's the model of your Gigabyte board? Is it a true Gigabyte board or a board made by Gigabyte for Dell, HP, Compaq, Gateway, etc? 3 beeps generally means a memory problem & as stated above, 9 beeps means a problem with the BIOS chip. But that only applies to the AMI BIOS.
I don't have the model of the gigabyte mother board because the PC is at office and i am at home at the moment. It was a gigabyte motherboard in an assembled Pc . was not made for Dell, HP etc. All the beeps are short. This is quite an old PC with a Celeron chip. We are a small company still uses these old machines.
The model of the board should be printed on printed circuit board. Usually somewhere near the edge. Will be GA *******ver.? One thing to mention is that even if the motherboard is faulty you should be able to migrate the hard drive/s to a working computer and access the data on the drive/s.
