I noticed that the CPU usage in my system goes upto 100% and after of couple mintues the system shuts down. I tried couple of anti-virus but could get rid of the malware/virus.
I see that the System Idle process shows 80-90% but at the same time the CPU usage is 100% .

I have NOT changed the size of the RAM that i am using.
Any fix that you guys are aware of?

reinstall.

When I used Windows machines full time, I'd that every six to eight months.

Is there any other option other than reinstalling the OS

There may be, but that is the one that I used, and it was 100% reliable.

Of course, you have to have made backups of all of your important stuff, and you have to reinstall all the applications you use.

Naturally, all of the source code you are using is backed up on something like git or svn.

what version of Windows are you using? Any changes made between the time you had normal response and the time you started to have problem? (installing new software, mapping network drives, installing/replacing hardware etc)

Did you try and boot into Windows Safe Mode; see if that works or not. If yes, then it could be one of the services or drivers is causing the issue.

Thats absolutely a virus/malware. Get your machine scanned. Do not try to install an anti-virus and then scan its too late by then. If you can take the hard-drive out and get it scanned from another machine it will be good else Pat's suggestions are 100% reliable. Make sure you are not on the internet after a fresh install. Have a anti-virus installed immediately after you are done with new OS install and then go on net.

If it is caused by malware, do you need to reinstall Windows®? You might need to install a new credit card, but that’s a different story!

i tried Norton and Avast both could not fix the issue.
I checked the System Configurations(msconfig), found that in Startup tab there were two process without any name or manufacturer. Unchecked those two process and restarted the machine.
Now it looks like the CPU usage is looking alright.
Let me know if this is not a good approach.
Thanks for your suggestion guys
