Intermittent and random lockups. Not consistent with any time or programs. Configuration problems with sound and with printer, works sometimes and not others. System slows down to a crawl every once in a while. If it sits idle for a lengthy period it will be shutdown when I come back. Left on overnight it will be shut down or locked up in the AM.
All this when configured as 64 bit. Runs smoothly and consistently at 32 bit. I know, "if it hurts when you hit it with a hammer stop hitting it with a hammer". I could/should use 32 bit and be done with it, but I don't want to.
