I tested the memory and i tested the hard disk and everything is fine!

Mini XP booted from Hirens Boot Disk works :(

I tried Windows 7, Windows XP SP3 and even Ubuntu 10.04 :(

All Operating Systems boots up to the point where they can load necessary files to start the OS and then resets the laptop

Windows 7, only up to the point where the Windows Loading Animation is happening

Ubuntu, only up to the point where the loading is done, shows a small screen and then goes to a blinking cursor and thats it... it keeps on blinking and sometimes resets the computer

Windows XP SP3, loads all the drivers and everything and then the point where i should be able install the OS, it simply resets the laptop :(

I have used the word reset instead of restart because the laptop completely turns off and then only turns back in

Any solutions would be greatly appreciated
