GPU disappeared from device manager after STOP error df
Hey,
Here is what happened: My laptop was overheating, so I disassembled it and cleaned out the dust buildup in the fan. I did not remove the GPU from its socket, I simply applied new thermal paste and reassembled the laptop. Note that in order to gain access to the fan I had to completely separate the motherboard with the GPU attached from the laptop case.
I turned on the laptop and it ran well. I checked for smoke, etc, and I was monitoring the CPU and GPU temperatures and they were normal. I began doing some internet browsing, and after a few minutes of that there was a BSOD. The STOP error codes are below:
Problem signature:
Problem Event Name: BlueScreen
OS Version: 6.1.7601.2.1.0.768.3
Locale ID: 1033
Additional information about the problem:
BCCode: 9f
BCP1: 0000000000000003
BCP2: FFFFFA8007C7BA10
BCP3: FFFFF80000B9C3D8
BCP4: FFFFFA8018148BF0
OS Version: 6_1_7601
Service Pack: 1_0
Product: 768_1
The computer restarted automatically and I tried looking up the code but could not determine the problem. The computer was still running so I thought it might have just been some temporary software issue. I did not realize that the computer didn't see the GPU anymore until I tried playing a video game which the integrated Intel HD Graphics 4000 GPU could not handle. The game shut down, and I noticed that the nVidia notification icon was missing from my task manager. I checked the device manager and the nVidia card is not showing up under any tab. I googled the problem and found someone with a similar problem on this forum.
Link is here: GPU is not listed under device manager
I followed that thread and uninstalled the nVidia driver and tried to reinstall it, but it could not see the GPU so could not fully install. I checked the BIOS version and it's up to date. The user stated that he solved the problem by restoring his BIOS settings to default. I tried doing this and the nVidia card still didn't show up.
I'm guessing it's a hardware problem, but I was really careful when reassembling the laptop. I never removed the GPU from it's socket on the mobo. Does anyone have any other options I could try?
