So am trying to finalize a HTPC build using Windows Vista Home Premium disc I had used with my old computer by taking advantage of up the $40 upgrade special. Specs AsRock h77m I3-3225 (using onboard graphics) 8gb Samsung Magic Ram 180GB Intel 520 SSD 3TB WD Red Asus Blue Ray Writer Silverstone GD04 Case 380w Antec Earthwatts So I updated my Bios on my Motherboard and installed all the relevant drivers with the exception of the intel HD4000 (not supported in Windows Vista so just using windows drivers). I also downloaded all the relevant system updates to be completely current. The problem occurs when I am installing Windows 8 upgrade, after the initial restart Windows 8 finishes the "setting up devices" screen, I lose video connection, then video connection returns and shows the blue windows 8 activity screen, lose the connection again, get the connection back, and then finally lose the video connection for good. After waiting for about 15 minutes, I restart the computer and windows 8 uninstalls itself. I was going to pick up a cheap video card from Best Buy to verify there are issues with onboard graphics, but wanted to see if anyone else had any ideas or potential solutions to the problem. Thanks!
