DWM.exe process keeps spiking

well this is my 3rd instsall of windows 7, each time a new problem arises, this time its the DWM.exe process,

it seems that randomly it spikes to 25% cpu and everything judders, the mouse stops working properly, the lights on my USB mouse go off and on, and its really annoying, im running virus checkers on it now

at this rate im going to reinstall vista, for all its faults, ive never had any major issues with it!

its begging to frustrate me!

DWM.EXE is the "Desktop Window Manager", and is the process that provides Aero effects to Windows. Have you tried updating your graphics card drivers to the newest NON-BETA Windows 7 version?

You are using an nVidia graphic card, so nVida would be your best bet. To make things easier for you, I took the liberty of locating it for you: Drivers - Download NVIDIA Drivers
