Same problem i hav faced 4 months ago..

My PC restarts at the time of booting process and sometimes it properly boots but it restarts before the login screen.. I hav tried my best to find the problem. after a long try my PC boots sucsessfully, but sometimes.

Than i replaced my RAM with new one. than the problem has gone..

you soud hav a try ...

don't buy NEW RAM .. but replace your RAM with your friend's RAM. and check it if the problem occures or not.
