Okay, wasn't sure where to post this so though, start here. My daughters PC was brought over for me to look at.....it will post (one beep) then the XP splash screen comes up...poof...restarts after MAYBE 2secs. Does this with safe mode as well....also when I choose from last known config. Without digging around inside yet, does this sound like a Mobo battery going?? I've never had one go dead on me, so I am unaware of symptoms. I can poke around in setup just fine...no restarts...but whenever I try to get into ANY windows of any type, it automatically does the 2 secs load then restarts. This will repeat itself if I let it be and watch. I can't get in to do a virus check...so not sure that would be it right now either. Any ideas are welcome...thanks
