Addendum
If you do not have at least 256ram
don't bother with sp2
CHKDSK IS WORTHLESS
IT ONLY CATCHES AROUND 65% OF HDD PROBLEMS
If it all still goes wrong and you do not want to put much money, try to aquire Win XP with SP2 or SP3 integrated
You need to have the minimu 256 ram though,and it will still be very slow.you honestly need 1gb ram if u want it to work fast with antivirus installed.if no antivirus is needed you can do quite well with 512ram.
