Make sure you check your system os. I got a hang on the benchmark because I boot from my old Hard Disk since Win 7 doesn't have 32bit for GUID on my SSD . Anyways, what the problem was being reported as was "DRIVER version info query failed".
If you get that then you have a hang in your hard drive. Use your system disk to run a system restore because your OS has corrupt data. My HD is a refurb from 2007 so it has its bad days. I'm currently without job, so my system is static in terms of upgrade. That leaves me with plenty opportunities to mess around with the current setup though. I'm like minimum specs to run a game guy
