I just built a new computer and first couple boot ups everything worked fine, but when I tried it the next day I got "Cannot Display Video Mode"and then after the system reset itself the screen looks all messed up with these weird vertical yellow dotted lines. I've tried reinstalling the drivers nothing works. System says Error 43 and it stopped the video card. There is no integrated video on my motherboard. After installing drivers it does the same thing before, I have tried doing clean installs.
AMD phenom II X4 955
G.Skill Ripjaws (2x 4GB)RAM
Nvidia GeForce 8300 GS
Once again no idea why it stopped working correctly, worked fine before, made no changes, next time it booted it started doing this.
