did you update your 3d drivers? its an issue w/open gl...

 

I have a HUGE problem! I tried updating my video card but when I did, it screwed up my entire system, everything looks like it's in safe mode (with those huge graphics) but it really isn't in safe mode and I can't change the graphics at all b/c when I restart my comp a bunch of errors about the device appear and screw my system up, How can I undo what I did when I installed that gay new driver?????
