Got a random hard lock. Rebooted and after everything loads in XP I can move the mouse but no start menu or loading of any programs. Booted into my dual booted W7 and ran a chkdsk on that partition and the box once again started acting funny. Googled unresponsiverness and got a bad hard drive or a bad cable. Changed the cable and seemed fine for about a hour. Now same issues. Is my 3 month old WD Black going bad or!?
