Hello there.

I am having problem with my laptop at the moment.

To begin, I would like to inform that the PC went into Blue Screen of Death (BSOD) while I was playing games.

This last for a few minutes before it automatically restarts and the BSOD states as such: THREAD_STUCK_IN_DEVICE_DRIVER

Upon restarting, I realised that the frame rates dropped significantly (from 60 to 20) while playing the same game. Of course, I let the PC cools down a bit, in case overheating was the root of the problem.

So, I went and checked my AMD Catalyst Control Center, only to realised that the Dual-Graphics option is gone. To clarify myself, I checked the device manager, and realised 1 display adapter went missing. There used to be 2 of it, despite of the display name being the same, as there is 2 graphic cards installed in this laptop instead of 1.

I did approached the AMD supports, however the solution suggested doesn't work. Installation went perfect, but the frame rates is not how it was before the BSOD.

Here is what I did If it does help in a way

1. Uninstall all AMD components and drivers.
2. Update my OS and downloaded the latest drivers from AMD.
3. Clean installation
4. Reboot when necessary.

These are the specs of the faulty laptop:

Thanks in advance. Sorry for a bit of reading, but I am getting anxious as there were no further replies from AMD Supports after a few days reporting this problem.
If you did a clean setup of Windows along with the drivers from the laptop vendor, about the only remaining possibility with the missing video card not listed in Device Manager is that the video card died. Did you happen to check for "hidden devices" also to see if the video card is listed there?

Oh yes! I didn't know about this hidden device feature.
I just checked it, and yes, the missing video card is listed there.
However, it says here, error code 45 : Device is not connected.
It also suggests me to reconnect it back so that it can work properly.

Since its a laptop, is disconnecting and reconnecting the video card back possible?
Or could this be another power issue like the unusable USB ports?

Thanks for the reply. Now I am getting somewhere after a few days. Appreciate it.

Hold on, what do you mean "another power issue like unusable USB ports"? Your USB ports are not working also? From what is happening could be a bad video card. If you can re-seat it depends on the laptop, but many systems come with the video chip soldered to the motherboard. You can try doing a BIOS update see if that helps.
