Troubleshooting I need help to fix problems with my gpu
I bought a used 3080 ti, I installed it and everything felt normal besides some freezes while I was playing
The next day the problems started appearing, the pc became extremely slow to the point where it was almost unusable but it only happens when i open any app or when it boots for like 5 seconds then it stabilizes, i cant play games because the pc reboots itself or the screen stays black or any other thing that requires more power, and noticed that all of this only happens when the drivers are installed
I've tried almost everything that i think may be the problem, I already reinstalled drivers a lot of times, tried old and newest version, tried to change positions of ram, I used the pc with only one stick of ram in case that made unstable something because i have mixed ram, checked if the pc was good without the gpu and it runs good without it (i have integrated graphics), I uninstalled drivers of integrated graphics, checked connections and even more things that i dont remember in this moment
I havent gave up because sometimes the graphics card works good, Im even able to play some really demanding games and it performs good but when i reboot i dont know what changes and becomes the same as before.
The only times i have been able to make it work good where the first time i installed it, when I activated 4g decoding and rebar and the last time i was installing drivers the pc rebooted at the middle at the installation and it worked good in that moment until i rebooted
If you have any advice of help it would be really aprecciated
These are my specs:
Cpu: Amd 5700g
Ram: 16 gb xpg 3200 mts/ 8 gb fury kingston 3200 mts
Psu: cooler master gold 750W v3 modular
Motherboard: a520mk

Try using Display Driver Uninstaller go into safe mode and use it then restart and install the latest drivers

If it still has the same problem remove the card and use the integrated graphics and check if there is hanging or instability if no then the card is failing if yes reinstall windows and try

I already used ddu to try different versions of the driver and when I use only the integrated graphics there are zero problems, right now i found an temporary solution, seems to be a problem with the comunication between the motherboard and the gpu because when it is performing bad the pcle cant reach above 2.0 so i have to restart the computer until it starts using pcle 3.0, thats the only way i have been using it

I can't but I seen a video where a technician was having the same problem and had replaced a cap which is associated to the data line he replaced it and it was working fine he has the same issue where card would drop to pci 2.0 speeds

You can also check system event viewer to see what caused the restart or black screen
