I did all the standard maintence. I use SpeedupMyPC (don't know if it is any good or not), deleted temp files, disk frag, I use Trend Pc-cillon for my virus protection and ran that. It showed no problems.
My computer:
Windows 2000
5.00.2195
Service Pack 4
AMD Athlon (tm) Processor
AT/AT Compatible 261.613 KB ram
55.8 GB
39.8 used, 15.9 remaining
I probably do not have enough ram and am running out of memory, but I do not want to upgrade this computer as I will buy a new one in the next couple of months.
