I'm running into some difficulty with my computer. It runs perfectly fine on integrated graphics. However, whenever I attempt to install and use my GPU (Sapphire 290x Tri-X), I get the following post codes:
4f 78 b2 9c a2
Likely 19 times out of 20, my computer won't start, the fans go full speed, and I get these post codes, but the few times that it does start, it runs fine. What could cause this?
ASRock Extreme4 z87
Sapphire 290x
Rosewill 750M
I also get black screens (computer just instantly shuts off) on videos and other 2D tasks, but there are no issues gaming. Like I said, the machine runs fine without the vid card, so I'm not having issues with other components and I've RMA'd my card 4 times due to this issue. Replacements show the same symptoms.
