Hi all, I've been experiencing some issues with my GPU's clocks,but before I send it to the laptop's service ,I would like to know what tools do the techs from the service use to diagnose a problem with a laptop's GPU? Do they use the same diagnostics tools which the laptop's manufacturers provide on their sites? The GPU is Nvidia GTX 960M,and it is a Lenovo laptop! From where can I download those tools? Please tell me! Thanks to all in advance! Best regards!
