Hello Zaph mate I have had a bit to do with Toshibas now you need to find out what manufacturer of the components you are trying to get drivers for becausevery often the mytoshiba site will quote somethims two.
So run this and find out what components are in the computer
Using HW Info
PART A:
You can test the volts on the PSU with HW Info HWiNFO, HWiNFO32/64 - Download < download the right bit version and close the right hand window select Sensors and scroll down to the power section where you will see what the volts are doing see my pic. In my pic the section (Nuvoton) with VBATT is a dead give away you are in the section for the rail voltages. There are other section titles and one that pops up often is ITE
Now the voltage on the different rails have to be within 5% =+/- of what is required or the machine will not work properly if at all.
See this for the rail voltage info
Power Supply 101: A Reference Of Specifications - Power Supplies (Section 2.)
The original right hand window shows the machine running and is handy for that but for looking at the components in some detail close it and use the main left hand side panel
FOR OTHER COMPONENTS
PART B:
Open each small square with + in it on the section the components are in and then click on the individual component/s (it will highlight in blue) - in the right hand side will appear all sorts of details including brands speeds and other essential info that particular device. See pic for example.
Use PART B: to find that out see pic it is of my Toshiba
Now also when you find out the manufacturer that component that is being used and look for the driver on that site you are better off using the PART NO on the sticker on the back of the machine see pic
