We need to find out why your system continually crashes and reboots. I'd suspect a hardware issue since it's been occurring from day 1, but let's find out what is being reported. Right-click My Computer, select Properties, select the Advanced tab, and click Settings under Startup and Recovery. On the next window uncheck "Automatically restart" and then OK your way out. From then on when Windows crashes it will stop on the BSOD (Blue Screen of Death) instead of restarting, giving you a chance to write down the error message (particularly the STOP code and file name, if listed). That will help tell us what the source is.

Aside from that I have questions:
1.) How do you know your RAM was damaged?
2.) When you say your hard drive was damaged, do you mean a corrupted OS or physically failed?
3.) What do you mean by "slight leckage of current in the earth about 6V?" Do you mean this is a laptop and the battery is leaking?

Let us know.
