PC sudden shutdown

Specs: Windows 7, 4gb
I have had a hand-me down HP Pavillion dv7 us-1450 laptop which has been shutting off on me randomly. It has windows 7 and 4gb of ram, albeit apparently it only uses 2.72 of them. When I checked the task manager it reached to 100% and the pc was moving until one day the PC was running normally for about a month, now, after a month that the pc was not doing any problems to me, it's back to move extremely slowly as well as shutting off. I have no idea why it does that and how come it didn't do it the past month, but it is troublesome the cpu reaches 100% very quickly, making my PC immobile.

Please help! How do I decrease the CPU in the task manager and make my pc run normally again?

I would recommend saving all of your personal data to an external drive or by transferring to another computer and do a factory restore (destructive restore). This will return the computer to its factory shipped condition and wipe out all of the accumulated problems. You will have to reload all of your programs that were not shipped with the system including probably your antivirus program, but it will be like getting a new laptop. You will need to make sure you have any install disks and any key codes (look for the windows sticker on the laptop to find the windows activation key).
If you decide to do this, remove all external drives, printers, etc., then you will need to access your recovery partition by repeatedly pressing F10 during start up and following the prompts.
Post back if this method is not to your liking and one of us will give you additional advice on tracking down the culprit(s).

You have to be a little bit crazy to keep you from going insane.

I think the above is a pretty drastic move. You obviously know how to use Task Manager, which process is hogging the CPU? There's also the possibilty that the CPU is overheating.

to mickliq - I have no clear idea what happened. A month ago my computer was running properly despite having programs like firefox, skype and even sony vegas running on the same time, now one of them can barely run. You think it may be a virus?
