Do you have access to another computer with a burner on it? If so, download UBCD Ultimate Boot CD - Overview make a boot cd from the .iso and run memtest. If it will post, but won't boot into your OS it could be memory going bad.

Did you recently do an update or install of some form? It might also just be a pooched OS install.

Thankyou i'll try that..
apparently it was a virus i believe
he rebooted the computer and now it keeps rebooting once it tries to get into OS
I believe it's virus but can it corrupt the harddrive to the point where i can't boot from CD
because im trying to boot it with a window CD

Do you have your bios set to boot from the CD first?

Then a virus shouldn't prevent the windows CD from booting.

Run memtest off of the UBCD disk and see if you've got a memory problem.

Can you actually get into the bios?

Pull the plug, check all mobo connections, especially the power on and reset
Check your power and reset buttons as one might be stuck on. Inspect all components
for any signs of a short, like a hotspot. Is the fan on your psu spinning? CPU heatsink still mounted properly; ie: a mount busted!

Reset your cmos jumper while your doing all this, properly grounded of coarse

Sounds like a voltage sensor or temp sensor tripping the safety to me

Unplug your hard drive and see if it will boot onto the CD.

I had a similar problem with a friend's machine. Turned out to be a dying PSU. It would turn on, then die any time it tried to access the CD or HDD. Try another PSU if you can.
