Virtual memory issue
 

Okay, here's my tech issue.

I just got the new patch for World of Warcraft. When I tried running the program it looked like a glitched NES game for a while, until I got a blue screen saying there was a virtual memory issue.
It was running just fine before the patch. I've dropped programs and files I no longer use, but I'm at a total loss.

There's a program called RegCure that has... mixed reviews. Not sure if I trust this or not.

Can someone point me in the right direction here?
