How do I find out what speed my computer is running at? I'm looking to buy some extra RAM for it and I need to know whether to get a pc100 or a pc133. Any ideas how I find out bearing in mind I haven't got a manual for my machine?
Do you mean by speed, processor speed? Most information can be found in the BIOS. When you start your computer, you'll see something like "press ??? to enter setup" (Usually DEL-key, F2, etc.). The information should also appear on the screen anyway.
As far as your memory question is concerned, take a look here:
