Basically, device manager is empty. Here's what happened...

ACPI wasn't workingc(it wasn't auto switching off) so I changed the computer type in device manager to a standard PC. Restarted and installed some stuff and still it didnt work right. Read some things on the m$ site and did them and it didnt boot right. Set it to last good config and then had to re-activate XP. Did that and then I couldnt view anything in device manager. Any ideas? My computer takes ages to load the drives as well. Have tried a BIOS update but that didnt help. PNP is enabled.

Will post any other info requested 2moro.
