After almost a year of working wonderfully, my home computer has suddenly stopped. I thought it was a thermal issue: from cold I could login and even maybe start firefox before it would freeze (screen became static, network died, etc.) but if I rebooted after that it would stop much earlier. Today it has become much more consistent: booting recovery (verbose) mode always gets up through: "[xxx] devtmpfs: initialized" and then hangs.
Things that work:
memtest86+ runs fine and reports no errors.
Grub always loads and stays loaded fine.
A Debian 32bit install (rescue) disk loaded and did not crash.
Things that don't work:
64bit Debian install on the main HD
A 64bit Debian install disk I burned today did not load past the menu.
Could the debian amd64 bit kernel not be correctly built for my computer? Any advice would be much appreciated!
