Hi, I'm not sure if this problem is solved by others but I'm just happy mine is so I hope this information will confirm the existing solution if any. Anyway my problem initially was... 1) CPU usage overshoots 50% constantly (mind you 2GB and not running any program). 2) dwm.exe recorded over 20k memory usage. I looked around other places and someone suggested that the BIOS should be upgraded but I was yet to see anybody confirming this solution but I tried it though and now my CPU is back to normal; 5% and below at idle. Hope this will solve your problem with Aero or other display crashes Tell me if it works for you okay?
