You were perfectly clear on what you did. Did you actually install the driver and are all the ? gone from Device Manager now?
Keep in mind that the Dell Windows XP Reinstallation CD only installs XP, regardless of what Service Pack is on the disk. It does not install any of the hardware drivers. That means you have to install the drivers yourself, one at a time, in the right order, after loading XP. And you probably should have installed all the drivers after loading XP SP2, before you updated to SP3.
So lets go through this again. If you haven't already installed them, the correct order to install the drivers is:
- Desktop System Software
- Chipset
- Video driver
- Audio driver
- Network driver
- Other drivers
Unless and until you install those drivers in order, your hardware won't work correctly. Reboot in Safe Mode (reboot and press F8) to load #1 and then #2. When those are done, reboot normally and install the rest of the drivers. I can't tell from the numbers you posted which video card you have so you'll need to know what it is, to find the right video driver.
As for the Utility partition, that was on the old hard drive. Since you replaced the drive, you don't have that partition any more, but you should be able to run the diagnostics from your Dell Resources CD.
