explorer issue crash restart

Hello, I recently purchased a new desktop with a vista64 premium home. The windows explorer keeps crashing and then restarting. For instance, when i rightclick on the recycle bin or on a hdd. Sometimes it crashes without right clicking- just when I am browsing files. It is very annoying and it practically renders my pc worthless.

I tried a registry cleaner and repairing windows using genuine cd and other windows doctor programs. I have all the drivers updated including the mb. gpu drivers. These solutions do not work.

I need help. Thank you

Download and install shellExview from the bottom of that link. Disable all non microsoft context menus, restart your computer and check
