The new GPU fails to turn on after the previous one was damaged.
The situation with your friend's GTX 1060 appears to involve multiple potential issues. Dust buildup seems likely, as it could have caused the electrical arcs and subsequent failure. The replacement card didn't start up, and the motherboard's HDMI output isn't working either—possibly due to dust or age. The LED display on the board suggests basic booting is possible, but further troubleshooting is needed.
Considering your PSU is 700W with an i7-7700K and 16GB RAM, it should suffice for basic operation. However, upgrading to a higher wattage PSU (750W or 800W) could provide extra margin, especially if you're concerned about power stability. It might be wise to test the new PSU in a controlled environment before committing. Seek additional opinions from others who have similar setups to confirm.
There seems to be some power or lighting issues on the board. It looks like the PSU might be failing, possibly due to a long period of dust buildup, which could have caused the problem. Upgrading the board would be a better solution than just replacing it, but it’s not worth the cost.
I understand the PSU is functioning properly and the system boots without any display output at the moment. I considered the possibility that the PCI-E power delivery cable might be damaged, but I believe the issue could be more related to the board itself. Since power comes from the PSU rather than the motherboard, it's reasonable to think the GPU would still show some indicator like fan speed or LEDs. Another point I made was that everything else seems to work, and the motherboard appears intact enough to boot the OS. I realized I missed having him test a different PCI lane from the one his previous card used, which was likely the top lane. I plan to have him try another lane next as part of troubleshooting. Could it be that only that specific PCI lane is damaged while the rest of the board operates normally? P.S. You're correct about dust—he lives in a very dusty environment.
You're verifying that the system starts properly without any screen display output.
I performed a BIOS reset and started from safe mode while testing the onboard video.
I haven't tested it yet, I thought it might be a hardware problem since the screen isn't showing any input. Still, it might be worth checking.
We switched to a different path and this attempt got the fan and lights active, but the video remains absent... unclear how to interpret this. Likely we'll need to swap out the motherboard next.
