Windows 7 High CPU Utilization

[HappyG]

I have a Lenovo T61 ThinkPad (Core 2 Duo 2.00Ghz & 2Gig RAM). I've installed the Windows 7 RC and since then my CPU usage sits on a minimum of 50% and often spiking to 100%.
Under Vista SP1 I never had this issue (I did an upgrade and not a clean install - I suspect that this could be the issue!) & I used to get about 3 to 3.5hrs battery life. Now I get 1 hour if I'm lucky due to this CPU usage issue.

Anyone got any ideas where I can start to look?

TIA

first things first, and you said it yourself - do a clean install! MS recommend it highly and it is worth the pain.

there may be a way to fix your problem but i wouldnt spend anytime fixing things on an upgraded version when a clean install will give much better results in the long run. What if you hit more problems futher down the road? You'll always be thinking "was it because i didnt do a clean install?!"

do that first and if it still doesnt work feel free to come back to this post and flame me for making you waste four hours!

The culprit is likely driver related, possibly program related. Only real fix is a clean install.

Agreed..

As is the case with the majority of these types of problems...
