Bridge Beta Slowing down other programs.

I installed Bridge Beta (13.0.3.686) and it worked well. However, it adversly affected the speed of other programs. Topaz Studio was so slow as to make it unusable. I uninstalled Bridge but no difference was seen. I had to do a System Restore to get things back to normal. I tried updating NVIDIA Driver as suggested but this failed because the Graphis Driver installed on my device is Intel (R) HD Graphics 4000 which is up to date.
