I resolved the issue in the end by looking to other sites on the web. I went to msconfig, and selected safe mode and vga mode there, rebooted and then got the desired result >> my lcd screen now functional in "VGA mode" and my operating system in "safe mode". From there, I ran my anti-virus and anti-malware programs from safe mode as recommended. My intent for doing this was to counter SLOW computer performance, and I wanted to rule out virus and malware as the cause. It turns out they were not the problem. I managed to speed up my computer somewhat by removing un-needed Services and Start-ups, but my old XP computer remains slow (over 2 minutes from boot to working, unfettered cursor).
