I use a razer keyboard and razer mouse but they would not work, I have them plugged in but they are not lighting up or working, I used my mouse and keyboard on my laptop and it works on there, I tried using different keyboards and mouses but still don't work, I tried different things like, trying to get to the boot menu but nothing happens,

my Network has also not been working, my families wifi is good but mine isn't, when I would press F8 repeatedly the wifi would has a computer screen symbol with a white circle, before that it would have a red x . if you know how to fix any of this please reply .
