If' it's not hardware, restoring the machine to its factory condition will clear it right up and is the right choice for folk that don't want to learn Windows or deal with infections and more.
My computer got the blue screen of death twice in one day. After turning it back on after the second time, I found it to be having all sorts of issues. My computer OS is W7, it's about two or so years old by this point.
1) The theme for the desktop is now Windows 95. I'm unable to change the theme for some reason.
2) The system will not connect to the internet. Via Ethernet or Wi-Fi, it doesn't register that it has a means of being connected to the net.
3) It does not register that there is an audio output for it, even though it's connected to a TV. I also tried some speakers, but it would not work with them either.
There's probably more issues than this that I'm just not aware of.
I know I haven't given enough information to figure out what might be the problem. Not the most tech savvy person around. Just let me know what more info I can provide, and I'll do so.
Appreciate any and all help.
