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?
Maybe I installed the incorrect driver. It gives you about ten different driver options. This computer will be used mainly for internet and some games. What kind of driver should I be looking for?
