It was okay this morning andit was working fine although very slow. I installed an antivirus on the computer (avira) and then shut it down to restart it. It doesnt boot up now, all I get when the computer starts is the initial windows XP splash screen with the logo and then it goes away and I have a black screen with a blinking cursor in the top left. And when I shut it down again and restarted it after that, I went through the splash screen and then some windows writing showed up followed by the words "keyboard failure". I disconnected the keyboard and it still says "Keyboard failure" when I restart. Weird.
I cant even get to safe mode by pressing f8. What doI do
