Computer help: Cannot Boot Vista Unless I Hold Power Button Down

Cannot Boot Vista Unless I Hold Power Button Down

have a dell 1520 laptop with windows vista home basic on it. It is the oem version.

This is very strange but when I attempt any of the following:
*Boot Windows Normally
*Reinstall Windows
*Recover Windows

The little Green Loading bar (vista) that says windows is loading just hangs until I push the power button fast without holding it down.

When I push Power for like .5 seconds it loads fine.

ALSO, when I first get back into windows the mouse does not move until i hold the power button .5seconds again.

This is getting very annoying.

I have done the following. (I have no warranty).
*Write zeros to drive
*reinstall all drivers
*slipstream drivers into new DVD using vlite
*checked hard disk for errors (o found, using GWSCAN)

Please give me any info as to what this may be.

Thanks SO much.
