    I have an old Compac Presario 866. On the "My Computer" properties it has: 80486 and 32.0MB RAM. I don't know how fast my processor is (nor how to find out)I only know that it is slow. I would like to upgrade but I was wondering if I would have to change my motherboard to do this. Please pardon my stupidity!

    Hey, upgrades are complicated enough to confuse anybody. To run a modern CPU you will need a new motherboard, power supply, and RAM, at least. A new CPU will have a different number of pins and fit into a different slot/socket than you've got on your current board. Your 486 used a core voltage of 5.5 volts, and modern CPUs need 2.8 to 3.3, depending on model--that's one reason for a new power supply. And modern boards use 168-pin memory chips, so you'll need new RAM.

    You could probably gain some simple CPU speed with an upgrade chip, maybe boost it to 133 MHz, but you'll pay quite a bit and won't get any of the benefits of the new bus designs, expanded CPU functions, built-in USB, etc that you get with a good board/CPU.

    Shop around on the Net and I bet you can find a decent Tyan or ASUS board for $80, a Celeron or AMD K6 chip for about the same, a case-power supply for $50, and 128 MB RAM for $130.

    Have fun--
