HP ZBook 15 G3 Base Model Mobile Workstation

does the heatsink matter for it to work correctly? i still have the old amd heatsink in but the foam is in the correct place for it to make full contact with the top, and i have a usb fan underneath it to help keep it cool, i haven't found a NVidia heatsink yet. by the way i cant even get it to work at all, so i will try making it use only the NVidia card and see if that helps.

EDIT: it is giving me error 43 and i cannot get it to work in double the way i was able to before. i will try to do single gpu and hope it doesn't screw over my computer.

EDIT 2: single gpu mode is on and it works fine, i just have to restart my computer every time i put it to sleep because it gives me a black screen...could it be because of deep sleep mode?

EDIT 3:my Bluetooth earbuds (they have a built in microphone) wont let me use the output and input at the same time, i have to switch to the earbuds internal microphone to speak, but i cant hear anything, and i have to switch the computer built in microphone to hear, but cant speak. any ideas?

EDIT 4: no audio device except bluetooth earbuds and built in speakers work now even after a reboot, im gonna try changing some settings in the bios and see if that works.

EDIT 5: i still have the same issue, and it is driving me crazy.

EDIT 6: i fixed the audio issue, still have the issue with having to restart the computer when i put it to sleep.
