PC restart automatically again and again…‏

 

Sometimes,our computer restarts again and again automatically.This Problem is discussed in this post…
When this problem arises, first you need to check some parameters..

i)Make sure your RAM is OK
ii)Sometimes,excessive production of heat in the CPU of the computer also leads to this problem.
iii)See that all power cables are connected properly without any loose connections.Sufficiency of power supply also needs to be checked in case of some new hardware that you installed. for ex: a new graphics card.It could be that the power supply is faulty. But this a rare possibility.

If problem is with (i),try to re-seat the RAM by taking it out and putting it back. If this doesn’t help you might have to change your RAM.
If you notice problem with (ii), then immediately shutdown and unplug your computer, clean out the fans, and see that all fans are working when you turn on your computer the next time.
