Regarding your slow computer it is sometimes a symptom of a failing hard drive. This is quite possible as you appear to be using a very old machine (nothing wrong with that. I do the same myself), but every Hard drive WILL fail eventually, being an electro-mechanical device. Even though you don't like spending money (who does?) it might be worth buying a new hard drive. That is assuming your motherboard is able to use a new SATA drive. If you are still using the 40 pin IDE system to connect the hard drive, there are interface devices which convert IDE to SATA. Hard drives are relatively cheap now, so a clean install of the operating system(s) is worth a try.
