Hi, I just bought a Gateway computer yesterday with Windows 7 preinstalled on it, and last night I tried to wake it from sleep but when I did, it didn't show the taskbar, icons or start button. All I could see was the background. I tried the "ctrl+shift+esc" method to fix it, but when I hit those keys nothing happened. I'm at a loss, and I don't want to return the computer! Help please?!
