Hey guys.. I'm up at work and I'm working on a system.. I installed Advanced system optimizer just to look at what it had so i could write those down and tell my boss about the program, so i un-installed. At this time spybot had finished and was going to start at bootup to remove the rest of the problems and norton antivirus had finished running, so I restarted and I'm getting the windows protection error. So I started in safe mode and Windows is performing an illegal operation. Then I do step-by-step and it shows the HIMEM.SYS is missing.. I'm making a startup disk, it couldn't find the cdrom.. go figure.. BTW I don't know the system specs, just that the os is 98se.. Any help would be wonderful! w00t
