Have recently had windows 98SE put on my pc, however this has left me with no sound & only 16 colours. As I am a bit of a novice is there a way I can found out what drivers I need to download without opening up the machine or taking it back? Have new digital camera & pics look terrible!!

Yes, Windows 98 does not have all the driver support for a previously working computer or laptop. When upgrading is is always recommended to keep a backup on disks or other media for video, sound, modem and other unique hardware before one upgrades to another stable operating system. The best thing to do for the video is to take note at inicial boot up; who the video card is manufactured by. This might be very difficult to see, as it might slow real fast. If you can open up the pc and look at the video card and get all and any details about the video card, such as manufacturer, model, FCC assembly number, video chip engraving, this will be the way that a tech would determine what video drivers will be required. Regarding the Sound, basically the same situation, although most comform to the creative sound blaster or windows sound system format. Good Luck
