8.22.13 Thursday. Pissed off Turned computer on, booted, logged in, few minutes in, hardly started - nothing running really - when it restarted by itself. It booted ok. I didn't log in but clicked "restart" instead so it can fix itself. It, again, booted ok; logged in, saw prompt re:"recovered from serious error" report - typical report when it restarts itself. Then a few, maybe two, minutes later, it froze. Manual restart -- error, can't boot, system32 config missing, repair with os disk, etc. Manual restart again -- nada, no post: fan on, cpu light on; but no beeps, no display. Repeated off/on attempts produced same results: fan runs, no beeps, no display. No joy. (The man told me later that I shouldn't have kept turning it off/on. I'll keep that in mind next time.) Reminds me of last year but without cmos error: October 2012 cmos battery change and hardware cleaning when we discovered the mobo's bubbled capacitors. Recommendation back then
