Crazy Graphical Glitches

[Eklipze3k]

Hey guys, check out these pics and see if you can identify the problem

Picture 1 - I drew a box around the glitch and - Picture 2 .

This problem first appeared last Sunday night. I had just installed a Belkin Bluetooth device. XP-SP2 installed it's native drivers and I installed the ones that came with the device, which incidentally didn't work. I then uninstalled the Belkin drivers, removed the device (as it wasn't essential at the time) and proceeded to play some NFSU2. I paused the game to make a cup of tea, came back upstairs to find my machine had turned itself off and when I turned it back on it had those crazy glitches all over the place.

I'm assuming it's got something to do with the Bluetooth but with the drivers uninstalled it seems unlikely. Any ideas ?


Thanks all

P.S. I'm pretty sure the only way to resolve this, as with many others things, would be to re-install windows but I'd like some suggestions about other things I could try first.

This is screaming overheating at me

Well the NVidia Display utility reports it's temperature as 47° ... which is warm admittedly but certainly not hot enough to be causing that kinda glitches. Besides which, it was running fine for a couple of weeks and then just started out of the blue, and even if I try it from a cold start (because I do tend to leave my system running) it still does it. However, I did suspect that the VGA RAM Chips may be overheating during gaming sessions, could that cause it as well ?
