Her computer has been giving her problems for a little while now...I can't say how long exactly. It is an hp computer purchased last year on Black Friday, and it runs windows 8. I know she only uses the computer for basic internet usage, school projects, and some computer gaming (minecraft, for the most part). The problems she's been experiencing recently includes random computer crashes, slow performance, an inability to access "settings" or other system tools (the icon is there, but clicking it does nothing. Also, the ability to shut down the computer properly is gone...there is no "shut down" button. Disappeared.
First, is there an danger to connecting this computer to my home wifi? If the computer is infected with something, can my wifi be somehow compromised?
And if not, what steps do I need to take?
Thank you in advance, for any help provided
