Win 2k not seeing hard drives

I scanned the forums and found similar postings – but I am running 2k, and my drives aren’t visible at all. I will try the registry suggestions, and testing the IDE cable again… but I can’t even boot from CD because it doesn’t recognize the drives at all. So even if I want to reinstall the OS, to XP – a clean install, it won’t boot from the CD.
The drives aren’t shown in the Bios – but in Computer Management, it says they are working properly. I downloaded the drivers and reinstalled them, but it doesn’t make a difference.

i have Norton running with auto update, Adaware, SPybot (which don’t seem to do much at all) and Microsoft anti-spyware which catches at least three trojans a day. This is also why i want to clean install – to get rid of these trojans and popups.

thanks
