The PC was built by someone else with no manual left. The chipset is from VIA. I have just read somewhere else to try uninstalling the VIA chipset drivers so that Windows uses its own inbuilt ones. This however hasn't worked. I will attempt to reinstall the VIA drivers.
How do I find what 'controller' the drive uses? I know the mobo only has two SATA ports, one being used by the HDD and the other by the DVD drive. Forgive me as I am not a hardware guru in any shape or form
