Windows randomly freezes. Mouse & keyboard then unresponsive.

I got a new machine recently and it all works fine, except the operating system seems to randomly freeze. When it does the only way I have found to get out of it is to manually plug it out and restart.

On freeze the keyboard and mouse become entirely unresponsive, the cursor does not move, nor do either click buttons do anything, if I'm typing somewhere the text does not appear, and Ctrl+Alt+Del doesn't bring up the usual screen.

I'm running windows 7 home premium on a 64 bit machine. I haven't found anything quite like this problem around so I thought it deserved a new topic by itself.

I can't think of what to do to determine the cause or any potential solution. Everything's up to date. I think all the drivers are too. I put in different virus software 'cause I thought that might be it.

Any ideas anyone?

Edit: The last time it happened I tried putting the keyboard and mouse into different USB ports, but that didn't work.

Edit2: I just went to my device manager and manually checked for updates for all the drivers, and it turned out my graphics card needed an update (I updated it myself about three weeks ago so I discarded this as a potential problem). So I installed the update. If the problem persists I'll reply to this message.

Your Edit 2 noted.

If the problem persists I'll reply to this message.
