I have lenovo y510p GT750SLi , windows 10
i had overheating issues so i changed the laptop thermal paste (using coolermaster gel pro).
there are two problems:
1. one of the GT750 is not working, i have the yellow mark and state this error in widnows device manager:
Location: PCI Slot 2 (PCI bus 7, device 0, function 0)
Windows has stopped this device because it has reported problems. (Code 43)
2. sound problem: the sound i don't know is dull and not clear with some cracks sometimes.
so any help please

So before anything I suggest you do some troubleshooting in the device manager. Do this for each of the hardware that you've mentioned. Post the the results here if you please.
Here are my thoughts on what could cause this problem:
Here are the possible solutions:
TIP: Before working on electronics try touching the ground with both hands, or touch any metal connected to the ground. This will prevent electrostatic discharge from your body to the machine.
I hope this was somewhat helpful

Hello, Thanks For your kind replay.
i did what you told me, i reopened and redid the thermal paste, at the beggining the graphic card still not functionig but after several hours it starts to function properly but the sound problem still.
it's like harsh and noise sound specially the high sounds, the driver is fine and no error there, when i put a headphone the sound is clear and fine.

Glad the graphic card is fine, that was the most important part
As for the sound issue, what you're describing doesn't seem to be a software-related issue. But it doesn't hurt making sure that it isn't. So try the following solution and see if it works, otherwise it's most probably a hardware issue and you'll need a professional taking a look at it.
If the noise is still present then there's no doubt that this is caused by a hardware failure. Be it disonnection from the motherboard, damaged audio chips or anything hardware-related. This needs to be checked by an expert. So don't bother reopening your case and take your pc for repairment.
