One of the computers at work recently took a crap on us. When it boots up, it goes to the screen where you choose either last known config, start up normaly, or safe mode. No matter what you choose after the windows boots up it goes to a blue screen and says physical memory dump for 1 sec, then it restarts. When I went to bios setup and checked the events log, it said CMOS battery failure. Does this have anything to do whith this? And what is the CMOS Battery?
