"PSPC8E-01F01YEN" is not a model number, it's a part number. The correct model number for this machine is "Satellite P300-20H".
Click on the Services & Support link at the top of the page to see what drivers are available. I believe this machine was shipped from the factory with Windows Vista installed. If this is the case, drivers won't be available from the normal outlets.
If you need for us to look further, please identify which hardware device you need a driver for by giving us the hardware id string available from Device Manager.
