Problem with watching video under Boot Camp!

[canyon]

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.

My macbook froze all the time while watching youtube fullscreen on xp pro after my ram upgrade. I ended up putting windows 7 x64 and it never froze again. Try a fresh install of windows since that worked for me.
