computer keeps restarting itself

[dhruva sharma]

my pc restarts its self before it gets start .no warning signal appers in my monitor and before i can acsses my acount it restarts automatically.i have bought a new ram of 2 gb but it doesnot work the problem remains the same

ram is not likely the cause ,overheating is a more likely cause ,look around inside for dust buildup

[jwenting]

good excuse to buy more RAM though :)

I think your computer operating system has any problem. Or it could be a Bio's Battery problem! Thank you

Try any one of the two steps:
1.Please remove ur RAM and re-insert it.
2.Clear the BIOS by removing the CMOS battery and restarting the system.

best solution in my opinion is to backup important data and format hardrive and reinstall windows ,
