The problem started when I uninstalled my ATI graphics driver and i used a driver cleaner.
After i restarted win7 and it got to POST the screen just went completely blank. So i Used system restore from the repair menu to get back on.
I found out that if I ran chkdsk the display just goes black after restart on startup and i have to use system restore to get back on windows7 not sure why this is.
When i right click desktop and choose 'Screen Resolution' it says No such interface supported. Also when I click items such as device manager in the windows explorer it does not do anything.
I have tried re-registering the DLLS but that did not do anything.
