|Well it's not a Windows problem because it's occurring much to early in the boot process to be Windows-related.|
That only leaves faulty hardware, or it can also happen when you leave an external drive plugged in whilst booting. Faulty hardware is usually bad RAM or a faulty/failed hard drive, or even a faulty motherboard.
You can test the first two with a bootable CD (if the laptop will boot from it):
Hard drive: test with drive maker's diagnostic software for DOS. The links are here: http://www.tacktech.com/display.cfm...
RAM: test with memtest86: http://www.memtest.org/
