So a day or two ago I cleaned my PC and booted it up again and couldn't connect to the internet, so I tried reinstalling drivers and everything but nothing worked so I decided to factory reset my PC and when I tried to install my internet driver (my mobo is an msi z77a g45 gaming BTW) it gives me the error message 'No supported hardware found in your system. The installer cannot continue' so I tried to see if my LAN was disabled in my bios but whenever I click "motherboard settings" or gover over the boot priorities with my mouse, my PC resets. Please help, I also had to cheap out in my motherboard and I got it from eBay it may be damaged do I just need a new mobo or can I fix it? Thanks (I have also tried to clear CMOS and that didn't work either)
