Computer Restarts Upon Graal Opening

[royce]

Alright so I got this computer 2 years ago, I played Graal on it as soon as I got it. Well I recently reformatted my computer and Graal doesn't work anymore. I upgraded my DirectX and all. When I open it I can see the server list it has fine but once I go to join the main game my comp restarts.

Here are my specs:
80gb Hard Drive
512mb DDR Memory
Windows XP Home
Built in GFX (Updated)
DirectX 9.0b (Newest)


Please help me if you can.

Is this as soon as it opens or after a bit of playing?

As soon as it opens. I can't even see the game it goes to like it going to load it and bam restart.
