Strange freezing issue, but only with FFXI (new graphics card, driver issue?)

[Neekzz]

Details:
Same issue here. PC freezes, locks up my system, noise thru my speakers. For me it happens in and out of abyssea.

Steps Taken:
I am a PC tech and have run full hardware Dio on my system using the dell hardware dio and the PC doctor Dio kit and found no probs so I went to the good old INTERNET to see it's not just me, its other ATI players as well. I have read post of ppl performing a clean install of just windows, FFXI and ATI drivers and still getting the same probs.
I recently uninstalled virus protection on the PC to see if it would solve the issue but haven't tested it cause I'm just playing on my other PC till SE accepts something is wrong and the probs go away.
I have played with my drivers a little recently in an attempt to get FFXIV working better. Seems I will have to go back a few drivers if i want to play FFXI again on my best rig, making FFXIV suck, again, so I won't. I'll play on my other PC that also rips the system requirements of this game to shame, runs on nVidia but still seems to have in game framrate issues of it's own.

Date and Time:
I can tell you that I have been playing on this PC about 8 months now and never have had a problem up until last 2 weeks. Since last update, It's been freezing more often.
