I'm sorry for you, but which distro are you using? None of my machines (and I use a few) exhibit such problems. All hardware works, no exceptions. No sound problems whatsoever, full screen Flash just works (why would it require a reboot?), and Firefox hasn't crashed any single time in a long time (maybe a year?), but I actually prefer Chromium. Are you sure your motherboard and memory are working OK?
