Screen flashes and kinda crashes

This is my first build andd it was for my brother. Specs are: Vista Ultimate 32bit, x3 Phenom II 720, corsair 650 PSU, G Skill 4 gig ram, GIGABYTE GA-MA770T-UD3P motherboard, and MSI HD 4830 video card.

Anyway, onto the problem. My little brother plays a game called Ragnarok Online and whenever he opens up two instances of the game and then he loads two of his characters from different accounts, a few or more minutes later the screen would just flash and sometimes weird lines would appear. Most of the time we have to reboot the computer and here is what the screen looks like if I was able to "somewhat recover" and have not yet rebooted the computer:

I know that it is not the video card since I just put my videocard into his machine and it did the same thing.

I'm still a newbie when it comes to this stuff so, any help would be appreciated. Thank you.

If you just poped your card in without installing the latest drivers then its likly a driver issue. Make sure you have the latest drivers installed. If that still doesn't help then monitor system temps. It may be overheating.
