I had this problem after reinstalling premiere on a system that had been running perfectly for months.
System: ASUS P5KPL-AM EPU / Intel Core 2 Duo E7500 / NVIDIA GeForce GT 240 / 4GB DDR2

I tried re-installing a clean; Win 7 64bit, Premiere CS6, + Nvidia drivers again from scratch but same problem.

I found a simple solution that may help others:

If you have an integrated graphics motherboard the system allocated memory (mine was set at 8MB) it might be clashing with the Nvidia card’s faster memory and causing a Open GL conflict.

I opened up the BIOS and set shared integrated memory to 0MB and after the restart everything worked great!

Hope this helps
