I recently bought a new wireless keyboard/mouse combo for my computer. I plugged it in, ran the setup disc and it worked just fine. I then restarted my computer to complete the setup and such and now windows won't start up. It shows the dell screen, and then the windows xp screen and then when it's supposed to show the welcome screen it just stays black. When I turn off my computer and turn it back on it says windows did not start correctly and gives me a list of things to do. Does anyone have any ideas why this happened and how I can possibly fix it?
