Ok so it started a few months ago, my computer would randomly restart, sometimes briefly displaying a blue screen. After a little while the on board sound on my motherboard (spec below) stopped functioning and reinstalling the drivers did'nt help. Later when my computer was on it would make periodical bleeping sounds every second or so, and then when it randomly restarted the bleeping would become momentarily sustained before the power went. Well i've got my system crammed into a rather small sugo case so I thought it could be a problem with overheating, anyway to play it safe I took it to a computer repair shop here in the uk. They had it for 2 weeks! when I went in to enquire they said that when they removed the graphics card (x1800xl i think) the system started to work fine. Ok fair enough I thought, I'll buy a new grfx card but in the meantime i'll use the mb's built in video. Anyhow when I got the computer home and booted it up it didnt take long to realise that the problem was still present (minus the bleeping). Further to that I got a friend to test the graphics car they took out and he found it to be perfectly functional. Arrrghh. So in the meantime I had allready bought a new graphic card and windows vista ultimate, so I formated my hard drive, did a fresh install of windows vista, put in the new card and guess what the problem still remains, and might I add, the sound still dosnt work on the board despite getting vista drivers from the manufacturers website. (also on a side not and cant find drivers for sata either).
I've acouted arround on the net for people with a similar problem (of which there are many) and unfortunatly the general consensus is that it could be any number of things, I only hope that by providing you guys with all this info it could narrow it down.
Incedently the computer just rebooted, I hoped straight into the bios to check the tempreature, the cpu is 51c and the system is 34c.
Now my theory is that the mother board in beggered, going by the fact that the sound is also not working.

thankyou in advance for your help, this is really driving me up the wall.

Hi and welcome to Geeks to Go. Randon reboots are usually caused by 1. heat, 2. memory, 3. driver issues, 4. the power supply. Examine each cause carefully to either correct it or rule it out. You can test the memory with memtest86 http://www.memtest.org/.

thanks, but can you be more specific, is the tempreature I mentioned TO hot, i think I can rule out driver issues, and dont you think the fact that the sound isnt working on the board is suspicious?

If the sound isn't working, you probably have a driver problem. See if you can correct that, and if the reboot problem goes away that was it. Random reboots can be tedious to work through because each of the items I listed is a potential cause and needs to be ruled our or corrected. I would agree it is probably not heat. Move on and deal with the driver issue. Then test the memory. Don't overlook the power supply. I had a similar problem with one of my systems. Turned out the power supply was the cause.
