hi there, Let me describe my situation. My name is Dmytro. I live in Austira. I am a student of architecture, mostly working in windows 7/64bit. About a couple month ago I have bought a new mbp (15''/2.2ghz/4gb/1gb video ati). I installed windows 7/64bit immediately. At first everything was good, but after changing the RAM from 2x2gb to 2x4gb. I noticed that some problems started to appear. When I am watching video (doesn't matter LQ or HD) after an hour or so the laptop just freezes. Sometimes it is just short-term freezing, but occasionally I get "blue death screen". Only rebooting the device help me. Myaby I accidentally damaged something when I was changing the memory, but I don't think so. I installed all updated for boot camp and for EFI. Nothing helps. When I am using LubbosFanControl 1.1.0 and my fans works about 4000-5000, then I can watch a video. But it is stupidly.. When I am playing or renderind - everything is ok, no freezes. If somebody have the same symptoms, please help me! Any suggestions are appreciated. Thanks.
