Computer restarts when entering game

[Pinn]

Hi. I played DDO back in the beta and decided to try it out again after I found out they came out with the free unlimited thing. Anyway, I made my character and when I click enter, my computer just restarts. The loading screen will flash for a second, but then just restart my computer automatically (as if I hit the restart button). I had all the graphic settings on high and windowed at first, but figured I'd try everything on the lowest graphic settings and full screen just in case. It still restarted of course. Yes, my computer is good enough to run the game. It's quite outdated now, but still good enough to run stuff like Fallout 3 on the highest settings. Any suggestions? Should I try reinstalling? Also, I should mention that the very first time I opened up the client and started making a char, the game locked up on me and I wasn't able to end task. I had to restart my computer and remake the char, and I didn't have any problems with locking up again.

Thanks!

Maybe your DDo is running on DX10 try DX9 or vize versa

Thanks for the reply. I am running XP so can't get an official version of DX10. I reinstalled the game and updated DX9 but it still restarts. Any other suggestions?
