Hey everybody,
i have a problem with my GPU and i cant fix it. Maybe some of you could help me.
I have a AMD Vega 64 Sapphire Nitro +with a AMD Ryzen 5 2600x and a 850 Watt Power supply. About 4 Months ago i got random black screens when the GPU is at 100 % but the PC stayes on, the MB shows that the GPU is disconnected. After that i have to hard Shutdown the PC. I tried everthing. Reset GPU Driver and so on. Now i even dissasambled the GPU and put new Thermalpaste on it. Still crashes. The GPU stayes under 70 Degrees and the "Hotspot" under 100 Degrees. The GPU uses 300 Watt min. What should i do?
Thanks to anyone!

Welcome to the forums, newcomer!

When posting a thread of troubleshooting nature, it's customary to include yours pecs like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:

850W is the wattage of the PSU, it doesn't give us any indication of the quality and model of the unit. Include the age of the PSU as well. What BIOS version are you on for your motherboard? Have you tried DDU to uninstall your GPU drivers? Reinstalled with the latest drivers for GPU in an elevated command?
