This is really really really pissing me off. Ok, so I got Call of Duty 4 for my WINDOWS side last week, and it's been playing fine ever since this week. Well, kind of. Last week, Call of Duty would like, crash to the log in screen, but it only crashed 2 times. It would first go to a black screen, while I still hear the sounds, but then the sounds would turn off and I could tap space ( wake up from sleep ) and then type in my password. that got annoying, but I found out something much worse. ( By the way, this has also happened to my GTA IV, although more frequent ) I haven't tried with GTA IV yet, but this weekend, since I started playing Call of Duty multiplayer, the game keeps on crashing to a black screen, and I can still hear the sound, but the sound never goes away, like the previous week ( it would eventually go silent ). I repeatedly tap space, and I THINK I hear the log in sound thing, ( you know when you type a letter or something wrong and the computer goes ding ), but the black screen never goes away. This forces me to force quit my computer. It's been happening at about every 5 minutes, and it's totally ruining my gameplay. Specs : Macbook Pro Snow Leopard 10.6 2.4 GHz Intel Core 2 Duo Processor 4 GB of RAM BOOTCAMP Windows Vista 40 GB free ( out of 97 ) HELP! This is really annoying me, and I've updated my driver already, and the problem still persists. Also, I've noticed my computer is kind of running slowly.
