I uninstalled it, powered down, and checked the HDD make, it's a Seagate Barracuda 7200.7.
I've now turned it back on, reinstalled the Wifi card driver via the disk that came with it, and now the 'Railink doesn't exist' no longer comes up, I still have connection to the internet though. I'm currently listening to music on YT, we'll see what happens, not holding out for much tbh
EDIT: Just froze again for a few seconds, time to unistall the graphics card, reinstall media accelerator/unistall, then reinstall graphics card. I'm close to giving up and asking for an exchange.
