computer turns off after 3 sec of turning ON Closed

Question

Hello,
THE COMPUTER IS A V2PREMIER AND IT IS ABOUT 5 YEARS OLD.  fOR THE PAST FEW WEEKS IT WOULD TURN OFF BY ITSELF AFTER USING IT FOR AWHILE.  THEN i WOULD WAIT A FEW MINUTES AND IT WOULD POWER UP AGAIN AND BE FINE.  Last week the computer would not turn on,  after several attempts it powered up and then after 3 secs it turnedoff and would not turn on again. I have read many advises but I can not do any of them because the computer does not stay on long enough.  I blink - it turns off.  My husband took the side panel off and dusted the conputer and the fan - he says tthat when the computer starts up the fan turns.  I am very much computer ignorant and therefore any advice would be great.  I read to clean out the CPU ( sorry -what is that, what does it look like and where do I find it? )  And clean it with what? please please help!!!!

From your narration i  guess two things

1.Power supply issue, i think the power supply(SMPS) is not working well.
2.The other issue is that the cooling paste on processor is worn out.You have to get  a cooling paste and remove the CPU and apply it.Ok

It would help you,revert me if any help needs,

THANKS SOOO MUCH FOR GETTING BACK AND HELPING - MY HUSBAND IS READY TO CHUCK THE COMPUTER BUT WITH FOUR CHILDREN AND ME BEING A TEACHER I NEED THE COMPUTER RIGHT NOW AND WANT TO TRY ANYTHING BEFORE SAYING QUITS!

YOU SAID POWER ISSUE - SO WHERE WOULD I FIND THE POWER SUPPLY AND WHAT DOES IT LOOK LIKE AND WHAT DO I DO WHEN I FIND IT?

WHAT IS a CPU?  WHERE IS IT AND WHERE DO I APPLY THIS PASTE?
