I was having a problem with my wireless router and went
through alot of problem solving with tech guys to get it
fixed. In the process some of the system files from the
registry are now corrupted and/or missing. This is an old
laptop and there is no original windows 98 startup disk. I
am having difficulty on the startup without the
missing/corrupted files. Is there any way to reset the
system to a previous time or day to get back the original
settings? Is there anything I can do to solve this
problem, or is it hopeless?

Thanks to anyone who can help
