Why does my Dell Dimension try to do a PXE boot?

Specs: Windows 7, Pentium 4, 512mg
I have a Dell Dimension 4500S running Windows 7. It never had a problem booting. Now it gets to the point where it has gone past the Dell welcome screen and then attempts to do something with "PXE boot." It then says it failed, and says "Press Ctrl + T to try again," with the same result. I've gone all through the Bios and it "shouldn't" be doing this but it is, and I can't get it to do anything else. HELP. thanks

If the network card is configured as a boot device with PXE, then what you're seeing is normal if the following conditions are true:

The HDD is set as first boot and it's not being detected, or, the NIC is set as the first boot device.

Check the "Drives" section in the BIOS and make sure that the HDD is actually detected. Also, check the Boot Order and make sure the HDD is set as the first boot device.

Pressing F12 upon boot will bring up boot menu options. There it will show any devices selected as boot devices. What's showing up there?

Yes, it is. And in the BIOS the PXE boot is disabled. So much for what that says!

Tapping F8 during POST should display the boot device selection menu.
Is the harddrive listed in that menu?
If you select the harddrive, any message?

Possible you harddrive is dead.

If it's trying to boot from the network then that option must be enabled. Either you're unsure about how to make those changes, you're not saving the changes or perhaps the cmos battery is dead and it's not keeping the changes.

And you're sure the hard drive is showing in bios setup?
