I have a HP envy 700-049 Core i7 12gb ram Radeon 8570 HD gpu. i put a new gpu (Radeon r9 380 4G) in and turned it on. It started and gave me the blue screen with the error. It would then restart and show the same error. After trying to repair it, I put the old gpu back I made sure all the wires were still connected and turned it back on. I gained access to the bios and made a full factory reset of the computer restoring it to Windows 8. It was a black screen my back lit keyboard turned on but not the num lock light still endlessly restarting. I then took out the old gpu and left it empty and turned it unplugged the video cable from the internal gpu while it was on and let it reset after 4-6 times I would plug it back in and let it restart a few times. About 25% of the time it would boot to Windows and everything would be fine. But if I turned it off I would have to go through unplugging it waiting and chancing it every time it turned off.
