I need help with Windows 7. Since two weeks I'm always trying to fix it.The first malfunction was a bluescreen that was my post automatically restart until you restart did not work. After several tests (Acer recovery cd not recognized by example), I managed to clear all with a reinstallation of windows 7. From the start, I have more than a mouse or keyboard, or over USB port possible (error in the Device Manager) or is the bar at startup (that of microsoft corporation) that runs constantly and my boot drive DVD also constantly to hang. Also the Corrupt/Unrecognized fonts are not being displayed in Windows 7 font manager. Please help.
