help me please.
I got a new gt630 2gb from my friend and it was working fine till yesterday.Today when I switched my pc on there were dots on the bios screen but it was gone when it booted up.Then when I selected NVidia control panel,it says that my gpu is not connected to my monitor eventhough it was.I adjusted the cable but no change.Then in displays and adapters ,it says that windows stopped my gpu(code 43).I reinstalled the drivers but no change.I know that it is a gpu problem and I am sure that it is not because of the gpu getting fried because it is new.Help me now my gpu doesn't work but is detected
I have a 430w smps
