Not sure what causes it but sometimes the computer refuses to shut down. The only way out is to physically press the Off button. I have XP Pro with SP2, Norton Antivirus and Norton Firewall, AMDI 64-bit processor with about 1Gig RAM, 30 Gig hard drive (master) and a 235Gig hard drive (slave). About the only software installed are a couple c++ compilers, Office 2003 and MySql server, but the computer is NOT used as a database server.
Any suggestions what to do about this problem? I just refrmatted and reinstalled everything about a week or so ago.
