je_saist, I couldn't get the Memtest cd to work so I entered BIOS and ran the Windows memory diagnostic instead. Not sure if it is as good as Memtest but it said no memory errors were found.

kinaki, I started having the problem soon after getting my pc but I attributed it to Vista and after switching to Windows 7, it did reduce but then it started up again. I don't think it was around the time I started any new programs but I recently uninstalled several programs I never use. No change to the problem.

Also, what happens is, the screen literally goes blank when I 'crash'. And then I have to restart the computer. Sometimes the color of the screen is blue, other times it is green, red or black. Never get any 'lines'.

I don't know how to open the case, I will ask my husband to do so and report back about the dust.

I checked Device Manager, there is an exclamation mark beside my 'coprocessor'. It says-

The drivers for this device are not installed. (Code 28)
To find a driver for this device, click Update Driver.

However, Windows tells me that it cannot find any drivers

So not sure what to do about it.

Anaharra: At this point I am willing to try anything. I shall turn shadows off and see if it helps any.

I really appreciate all the help you guys are giving, thanks so much. I hope this irritating problem goes away!!

I have had my pc for about a year now. It insists on crashing every once in a while, usually when I am playing CoX or watching a movie on Netflix Instant. Soloing in the game has become a pain because often I crash and get killed while I'm offline. I average about 3 crashes a day. I did a CoH Helper diagnosis and here is the output- does anything leap out at anyone? My pc came with Vista but I put Windows 7 on it because I was offered a free disc. I got the latest NVidia drivers yesterday and still crashed twice today!

I am not tech savvy at all. Please help if you can.
