Strange graphics problem

I was playing the sims 3 last night and  suddenly everything looks like this:

I don't know if it's my graphics card,  I know I have more than enough memory my computer has 500GB. Anyways I snapped a few pics to show the problem, and exited without saving only to find my desktop looked like that pic and I couldn't click on anything! I was forced to unplug my computer, and when I restarted it everything was fine.So, any ideas on what happened and what I should do?

Let's start with your computer specs first, please. When asking for technical help with your computer it's always good to give that information. It could be an issue with your graphic card, but it's hard to say without knowing more.

And once again, memory (RAM) is NOT the same as harddrive. You can't have 500 GB memory on a regular computer (unless you've got a computer cluster, of course). Most people have regular laptops or stationary PCs, and 512mb to 8gb memory/RAM is what is normal for most personal computers.

If you tell us which OS you're using (operative system - like Windows Vista/XP/7, or Mac) we can help you with where to find the comptuer specs, if you don't already know.
