I have a Acer aspire desktop and every time I boot it up it freezes on the acer logo. There is no tone, the acer logo just sits there. Pressing delete (to to enter BIOS) or F12 (for boot option) does nothing. But when I restart it, it works fine. I checked if the RAM was loose, which had cause previous problem, but that wasn't the problem, but anyway I took it took it out and swapped them. I have two kingston RAM. Any help would be appreciated.
