Been away from boxing for a while and decided to get back into it. Got myself a spanking new PC with Vista 64 and installed WoW, sadly, can get to the character load screen, choose a char, load the game and then it freezes. CTRL-ALT-DELETE doesn't work and no response from CAPS-LOCK or NUM-LOCK so am forced to hard-boot. Have put a message on Blizz tech support to see if they have any general guidelines but figured a fair few boxers here probably have Vista 64 so just curious if anyone has had a similar experience?

PC is pretty high spec with Intel i7 quad core, ATI Firepro V5700 with 12 Gig of Ram. Nothing else out of the ordinary, had suspected the graphic card as it's more business focussed but am aware of someone with an NVidia 8800 having similar problems.
