Hopefully, someone will come along with the exact instructions soon.
Oddly enough, Win2k is the one and only Microsoft OS that I've never personally used . . . I've suffered through all the others, now using WinXP.
To make the CD-ROM bootable, you need to reboot your pc,
and enter BIOS Setup.
Before rebooting, place the Windows 2000 CD-ROM in the drive.
If it auto runs, just close it.
If you've never been into the BIOS / Setup before, on the 2nd bootup screen where it detects and lists your hardware devices, you should see different options listed at the bottom. One of these will be "Setup", and it will also tell you which key to press to gain access. This is usually "Del", but could be F2, F11, or other.
The BIOS / Setup menus and procedures also vary per machine.
It depends on the pc manufacturer, or if no brand name (self/custom built), then it depends on the motherboard and BIOS manufacturer/provider.
In the setup, you'll be looking for "Boot Sequence"
In my BIOS, this comes under the "Advanced BIOS Features" section, but as I said, it could be different for yours, so (if you have one) refer to your motherboard manual.
You will need to change the Boot Sequence to:
1st boot device = CD-ROM
2nd boot device = IDE-0 (this will be your main hard drive, usually C:/)
Before you make any changes, take note of what the current settings are, because you will need to change them back afterwards.
Save the Settings
System will now reboot, and the Windows 2000 CD Setup screen should appear. Here you will be presented with all available options, and I assume that one of these will be "system repair".
Hopefully johnwill or another member will return with confirmation and exact procedure instructions.
What I was going to suggest was that you temporarily remove the cable modem (ie. unplug it) and see if the Stop Error still occurs. If you have a dial-up modem installed, you could also temporarily use that, just for troubleshooting purposes.
If the Stop Error no longer occurs, then you will have found the culprit.
Uninstall all the software for the cable modem.
Reinstall the software
Plug the cable modem back in.
If the problems start up again, then it's time to contact the cable provider.
Maybe they've got some new updated drivers available?
I also suggest that you download and run
StartUpList
and paste or attach the result file here.
You can run StartUpList in normal mode for a standard result file,
or via Start -> Run with a switch to produce a more complete list.
"c:\path.to\startuplist.exe" /complete
(replacing \path.to\ with the correct path)
StartUpList will show us all current running apps/processes, plus a list of everything loading at startup. This will help us to determine whether or not you've been hit by a virus, trojan, or spyware.
