I have just inherited a fairly old PC and have loaded up W98 for my young son but the number of colours is stuck on 16 and can't be changed. I haven't a clue which motherboard it is, nor do I have a disk for it but the graphics are built in, as is the sound. It is running a Pentium lll 667 Mhz chip. I also would like to change the refresh rate as it is flickering too much.

Any help much appreciated.

If it's an old PC the graphics chip most likely has only sufficient memory for 16-colours. You have two choices:

1. On-board graphics often use system RAM which means it can sometimes be configured to use more RAM in the BIOS setup configuration. The downside here is that you'll leave less RAM to run the operating system and programs, and there may not be much of it to start with.

2. Fit a new PCI graphics card with at least 8MB video -ram (if it's a very old PC it may only have ISA slots (no PCI) and ISA graphics cards are as rare as hen's teeth today. Even PCI one's are disappearing fast . I would think a little 'one-off' PC shop is your best bet, or mail order/internet.
