Yeah, 32-bit ix x86. Install the wrong drivers, and you're going to have a bad time.

Was it this slow before you installed the drivers?

And did you install the AHCI driver from Acer? Generally, you shouldn't need to install the AHCI driver or the motherboard chipset drivers as the WIndows installer automatically picks them up.
