Looks like the only chance I have is to try to completely wipe the disk and reinstall it, but I would really like to find the reason for all this ... What is actually done after POST is complete (on a technical level)? If the system freezes with the hard disk connected (and even with "booting from harddisk" disabled in the BIOS), what could cause this? Can this even be a GRUB/"bootloader" issue?? --=20 Udo Rader bestsolution.at EDV Systemhaus GmbH http://www.bestsolution.at --=-nBQ1kvXvRvKinD1D2QU2 Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (GNU/Linux) iD8DBQBHAimLuhFd84GLxP8RAorsAKDQSofwpTzHHl/YXxcpZi08lXovIgCbBB8z A1XiERrOSyjgOWxPJKEc2No= =xCOp -----END PGP SIGNATURE----- --=-nBQ1kvXvRvKinD1D2QU2--
