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

Can you boot from a live cd of sorts and use that os? Run from a remote drive? I am not suggesting that as a solution, more to get an overview over what is happening. If you get to access your internal drive you could check logs from the ubuntu boot. – daramarak Jun 16 '10 at 14:58
Yes i can login using MiniXP which a slimmed down version of XP from Hirens Boot CD. Where do i find the Ubuntu logs? – Ranhiru Jun 16 '10 at 15:08
I had a machine brought to my desk having exactly the behavior you described. It turns out the CPU failed and destroyed any movhpd operation. – Andrew Moore Jun 16 '10 at 16:23

Is your BIOS up to date?

Have you changed anything in the BIOS at all?

Try flashing it to the latest version then applying it's Defaults option.

Have you ever tried flashing your BIOS without an OS? – BloodPhilia Jun 16 '10 at 14:42

All the time. Floppy disk, bootable usb key (minimal dos boot), or bootable cd (again, minimal dos boot) are all almost always available options to flash a bios. Consult the motherboard docs. – basszero Jun 16 '10 at 14:53
Yes i have flashed to the latest BIOS using MiniXP. And then i even tried the previous version of BIOS, but nothing seemed to work. And yes i reset the settings to default but still no luck – Ranhiru Jun 16 '10 at 15:00
@BloodPhilia - From your comment I guess you are quite new to the world of PCs :) I remember when flashing the BIOS from within an OS seemed like an impossible dream :D – Shevek Jun 16 '10 at 19:47
Lol... I just said it would be pretty hard to flash the BIOS WITHOUT having an OS installed... – BloodPhilia Jun 16 '10 at 19:55
