Lucky Linkshell - Phoenix

I tried playing the GRAW demo on my computer today and what ended up happening was I either fried my computer internals or just burned through a a hard drive.  

The computer keeps hanging on the welcome screen in windows before the logons are displayed.

So far i've tried a repair install but it too freezes at a certain point.  I've connected the HD via USB to a laptop to scan it for problems.  So far no problem with defrag or viruses.  I haven't done a surface  scan yet but I plan to tomorrow.  I really don't wanna sit through a like 4 hour installation of ffxi and a reinstall of windows and all my apps on a new hard drive ;;

Anyone have any suggestions?

run a memory test
