I have a Gateway GM5260 PC and when I press the power button, the computer turns on, takes a few seconds and then goes to the Gateway start up screen (with the Bios settings and Boot menu options) and it just stays there. I've tried waiting, by leaving the computer on and nothing. I can't press F2 or F10, because it doesn't do anything. And if inpress the power button it automatically shuts off, which it usually doesn't do (you would normally have to press the power button for about 3-5 seconds for it to turn off). PLEASE HELP IT'S AN EMERGENCY I HAVE A PAPER DUE TOMORROW!!
