Right now I am trying to stay clm. I did the MS upgrade advisor, and everything checked out, did a complete virus scan, and that showed clean. This morning I went to install Windows 7 Home Premium. The files copied and decompressed with any issue, then the computer went to reboot. That was it, no bios, no Acer screen, no nothing. I spent 45 minutes on the phone with Microsoft technical support, unable to address the issue. They sent me to Acer which were totally useless. They gave me a link to update the BIOS, problem is that the computer is doing absolutely nothing. Any Help PLEASE!!!!
