Screen Tearing when Two boxxing

[Sleven]

Anyone that can offer me some help on this issue would rock. When I load up WoW I can play one charachter fine but when I load the second window the window behind starts to like project through the first. Then the graphics on both windows begin to degrade and turn into wierd checkboard patterns. Thats the best I can describe whats happening. If anyone can think of any fix that would rock.

Thanks

I experienced that back in the day, it was my video card over heating / not enough power.

Check to make sure your system isnt melting, and Id make sure your powersupply has enough juice.

I ran a system for about 2 years with major heat issues and just barely to little power.

I thought my card was fried, threw in an 800 watt powersupply for a new upgrade and was blown away when my little graphics card started performing 200x better.

Anyways just my personal experience with that, good luck.
