I recently installed Win8 64 bit I obtained via MSDN into my Acer 5560G and downloaded and installed VGA, TouchPad, and Audio Drivers. Few weeks after i installed windows 8 i started running into problems. The HDD indicator light flashes continuously and Windows Task Manager shows 99%-100% HDD usage. Computer freezes up and becomes unresponsive. It happens every time i leave the computer idle for a while or when i boot up from hibernation. I used recovery and now i'm back in Win 7 and nothing like that happens in Win 7. I installed win 8 32 bit i obtained via MSDN in my Hp-mini netbook and there are no problems what-so-ever, but the acer one is giving me hard time. Please help!
