How can I make my Win 98 computer reboot itself automatically every
24-48 hours? This computer  runs 24/7 to manage a Satellite search
program but slowly fills a buffer that interferes with its function
after a few days. Rebooting clears the buffer. I can automatically
reload the app after a reboot.

Hello!
I've found a free program that performs exactly what you want to do.
Follow this link

YaSoft | Switch Off
http://yasoft.km.ru/eng/switchoff/

I've tried it, it should work just fine. Otherwise, you can also try
this one

PowerOff 3.0
http://www.softnews.ro/public/cat/13/7/13-7-35.shtml

It's also freeware. Furthermore, for $10 you can register the
following shareware program (although it does exactly the same as the
previous ones)

Power Control Center 1.7

Finally, you may want to check the list of "Launchers & Shutdown
Tools" program list at Download.com. Some of the software in this list
do what you need.

I hope this helps! Let me know if you need further assistance with
this question by requesting a clarification, otherwise I await your
final rating and comments.
