Games crashing / Freezing after 2 minutes of play

[SamG]

Hi,

When playing games ove the past moth they have been pausing for about a minute every now and then. When they unpause I end up on the other end of the map. For example WoW and now COD2 is doing it.

Now over the past week games have been hanging when I exit them. Then they either crash or I have to try and get into Window Task Manager and shut them down that way.

Now games are crashing after 2 minutes of play for example Doom 3 and COD2. They either crash to the desktop and I don't get a message or a message saying send microsoft report and thats it or crash to a blue screen saying windows has shutdown and then just reboot.

I'm running a 7800Gt at stock and it hits a max temp of 75c.

I've tried 3 different drivers and still the same problem.

Any ideas what is wrong?

I have no idea of what you just said

what is HTT and a divider?

I forgot to mention i'm also seeing sparklies / flashing colours on objects and sometimes lines that aren't meant to be there.

Thanks for the help everyone!

I ran error checking on my hard drive and no longer any problems, so far.

I didn't think the hard drive would cause the sparklies I was getting in games though.

Any way thanks again.
