Windows 7: Mouse/render lag with nvidia when CPU is idle

Mouse/render lag with nvidia when CPU is idle

Hello, I didn't now where to write this so I'll go here. First of all, I'm quite an advanced user but when it comes to Windows maintenance... Gah Okay, so my problem is quite weird. I have a laptop Dell XPS M1530 with Windows 7 on it (32 bit). It has 2 GB of ram, dual core, nvidia 8600m gt video card, 15'6 monitor. The problem is if my CPU is (are) idle I start noticing some sort of lag in mouse movement and window moving/resizing is really jerky. It feels like fps drops way below than it is with a busy CPU. It happens either with Aero or without it. I've tried several different nvidia drivers (270, 260, 195, etc) and neither fixed the problem. Also installed the newest chipset drivers. It just starts lagging when my laptop is idle (I use 270 version drivers (proprietary) no matter what I do; on Linux such problem does not occur, I know it's not the same but maybe it's relevant). Any ideas and help is appreciated Cheers and have a good day.
