I have a new HP Pavilion 500-314PC with windows 8.1. I play World of Warcraft and the onboard video sysem is not fast enough to give me proper fps (frames per second) refresh. I bought a video card to install but this windows system doesn't recognize its installation and fails to boot with it installed in the PCI-express x16 slot. Also, memory upgrade fails when installation of 2 4G cards are installed.
What is the solution as I have tried most of what has been found by googling for solutions. I have the AMD catalyst installed and the video card drivers will NOT install unless the video card is installed. However, the system won't boot when the video card is installed.
