Could a video card make your computer reboot?

Well, ive been randomly rebooting for a while now. Seems to happen on the desktop, or in games, just about anywhere actually. It makes a quick buzz sound then reboots. I've swapped ram, thats not it. I've swapped PSU's, thats not it. I put my new x800 pro in my friends comptuer and it didnt have this problem but I only tested it for about 5 minutes in his computer. I'm guessing its my old AMD ATHLON 2700+ XP dieing or the mobo. If it was the video card I would be extremly screwed cuz its so expensive. I'm just wondering if a video card could constantly make a computer randomly reboot and make that sound.

Check the card temps and see if those are in line. It's possible that's one problem. Also, if you had a non ATi card in there before, make sure you uninstalled the old drivers, as well as that the card isn't listed in the Device Manager in safe mode.

Yeah, sounds like your video card. I know this almost positively because I had the same exact problem. Some times the screen will just turn either black and reboot or flicker and distort, then make a horrible noise that could blow one's ear drums. This was after I had my FSB set to 236 on a mobo that didn't have AGP lock. The damage was not reversible.

Your video ram is over heating. Considering stock speeds on a x800p is 450Mhz(x2) on the RAM, and you have it set well beyond that. Which only means your card cannot handle the overclock. I can only hope you have AGP lock set on your Nforce 2 right and its not faulty.

Set the ram speed down to 500 Mhz at least and see if problems still occur. If they do, I would RMA it as quickly as possible saying it had faulty RAM which is a common occurrence anyway.

I'm wondering if that "buzz sound" might not just be the power-supply, possibly overloading/overheating and then just shutting down?

What brand/wattage is the PSU in the system with the X800 Pro?

An overclocked video card can definitely reboot a machine. I left an overclocked card in my main rig (Radeon 9800) and it would constantly crash. Weird thing is, it would only crash when I was away from it (I leave my computers on at night to act as servers). Once I put the card back to stock settings, it ran fine.
