Rebooting

New system:
AMD 3500+
Gigabyte mb
1GB DDR memory
200GB HDD....

During installation Windows recognize 200GB HDD, it's ok, but after "Setup is copying files" computer keeps rebooting. If install on 80GB ATA HDD installation is OK.
Any idea what could be a problem??
thanks

Is the version of XP you're trying to install at least SP1? If not, then that is required for 48-bit LBA support (which is any drive over 137gb requires).

Yes, it is win XP Pro with SP1

seems very hard question

Test the RAM. You can run either or both of these utilities from a floppy:

Memtest86

Windows Memory Diagnostic

Thanks SuperSparks. Motherboard was faulty
