Random Crashes and Restarts

For about a week now my computer has been crashing and restarting. When it happens any audio will begin to lag and then stop working completely. I don't know whats causing it as it happens without warning and it seems to happen on whatever i'm doing e.g. iTunes, Youtube, Games or just using the internet in general.

When i turn the computer back on and log in i get a box saying Windows has recovered, with details:

Problem signature:
Problem Event Name: BlueScreen
OS Version: 6.1.7600.2.0.0.768.3

Okay, did you update to the latest drivers for your graphic card just recently?
Did you updated to service pack 1?
What's the age of all the hardware?

Code:

Start Menu\Programs\Norton Internet Security	Public:Start Menu\Programs\Norton Internet Security	Public

Suggest you to uninstall Norton, it's known to cause BSoDs.
Download and install MSE (at least to test). Make a full scan once installed and updated

• Norton Removal Tool
• Microsoft Security Essentials - Free Antivirus for Windows

Too early to say anything just observe. Is the computer under its warranty?

Do you have another video card to test with? or a friend or neighbor whom you can lend from?
