Everything was working fine but until I updated the Windows Player and also the Flash applications. Later on, when I made a try to type, the whole thing was frozen and couldn't type anything and the mouse was too unusable. Another problem was now that the only way for getting the computer to boot up is by pressing the F12 while rotating on the power. Boot menu also comes up, when I select a hard drive. Then I can easily browse the web by using any of the browsers with the mouse working, until I try to type anything in it again. I have also deleted the upgrades. I have also observed the works keyboard error (or something like that) which flash for a second on the screen before it goes somewhere else.

Help will be appreciating!!!
