Hello, yesterday I had to re-install windows XP on a computer that was full of mal-ware and spyware. Everything went fine, but then after everything was installed and the computer booted up, I got a message that said the monitor was set at very low resolution. When I went into display properties to change it, it was set on 600X480 and it would not allow me to change it. It has monitor type as default monitor. also when I go into advanced it will not let me click on the monitor properties button. Any ideas? thanks!
