Unusual flash issue. Flash causes mouse to flicker then freezes on all browsers.

I've reinstalled flash, cleared settings, cleared cache, checked on another user account, etc. All was working fine before I did a new SSD install. I copied the older hard drive to the SSD and everything else seems fine.

When loading a page with flash on it, if its simple flash it may run but not allow you to scroll. If it is more complex like a video it freezes up, the mouse might disappear or flicker alot while this is happening.

Other current issues include that the screenshot and grab program does not work. And some screen savers said they could not work on this version of OS X (I'm running 10.6.8)

Thoughts? Could it be the graphic card even though it was working fine before?

Thanks so much in advance
