I don't suppose you also studied the capacitors on the motherboard. Are any showing any signs of bulges? Have you tried reseating everything? >Flaky CPU? Flaky power supply? How might I tell? CPU shouldn't go flaky unless it's been overheated. In my experience, PSUs are the least reliable part of consumer-grade hardware but about the only way to check is to swap it. If you've got a DMM, you could check all the rails but there are lots of failure modes that won't show up that way. Have you checked the voltage/temperature screen in the BIOS? Does anything look abnormal? Are you using a PS/2 or USB keyboard? Are you running X? At this stage, my suggestion would be to try swapping the PSU. --=20 Peter Jeremy --nFreZHaLTZJo0R7j Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.13 (FreeBSD) iEYEARECAAYFAkr7qrwACgkQ/opHv/APuIeOsACeMLESzppG0HeNcif07L5Fln+e BWEAnivIPZ+wBnsj3oqjUqKDeqJ1lBeq =tIoN -----END PGP SIGNATURE----- --nFreZHaLTZJo0R7j--
