Errors during scandisk

[bluedos82]

I get alot of errors when I go into scan disk on this one computer. It gives me that 'Scandisk has restarted 10 times...' stuff and it will not fix. I tried to defrag it last night and nothing happened. I have also uninstalled some programs that I knew were bogging it down and it is still slower than christmas.
Here are some specs:

OS: Win98
Processor: AMD-K6
and 62.0MB RAM

Any ideas?

Boot into safe mode and do the scandis and defrag there .safe mode hit f8 on bootup
