unexpected-shutdown

I have no idea, what is happening to my laptop. For last 5-6 times it has automatically shutdown while running, without doing anything serious. And I even do get the message during boot which says
- Start windows normal
- Start in safe mode
It just boots up normal.

Few days ago, my screen blinked and it the PC shutdown immediately. After that I was not able to get it started. I got it repaired, the guy said he has replaced the display chip (nVidia-nvs-140), but i seriously doubt that. Now it started working, but would shutdown every 20 mins or so. I have a dual boot, ubuntu-11.10 works just fine.

Virus scan on windows shows nothing. I am pasting my perfmon output. My CPU for reason is maxing out to 100% continously, for windows internal processes. Please have a look at the attached file.

Strangly now for last 2 hours it is working fine, but i am just writing emails and reading excels.
ThinkPad T61 | t9300 | 3gb | nVidia 140 nvs-quadro (latest driver 296.10)
