text: how can i fix display problems after reinstalling the os? after reinstalling xp home edition my display settings were set at a very low level and i can't seem to adjust them. i went through the troubleshooting process but some of the options it suggested i was not able to access.   the computer was very buggy, adware, spyware and viruses out the yinyang. it was beyond using antivirus software or anti-malware software to repair it.  is it possible that the reboot did not remove all the malware? would using a good hard drive eraser solve this problem? or do i need to look at other options? the monitor or display of a computer is the primary user interface. monitor problems are some of  the most common computer problems since the voltages inside a monitor can be as high as 10 kv. many of the problems can be fixed yourself by simply changing the settings. detailed instructions available at   http://fixit.in/monitor.html
