I bought a T500 back in 2009 and it came pre-loaded with Vista. In the past few months I've since upgraded to Windows 7 64bit and have had problems with the computer freezing up, seemingly at random.It never did this with Vista, so I'm inclined to think it's a software problem rather than a hardware problem.
-screen goes black
-computer completely non-responsive (have to force a restart by holding power button down)
-if any music was playing then the speakers get stuck on the last sound and cause a buzzing noise
I think the issue might be with the drivers, but even after installing all the seemingly appropriate drivers, the problem persists. Any thoughts? I figured I'd ask here before taking it into the shop.
