hi there i have been using toshiba SATELLITE L70-B-150 with AMD Radeon™ R9 M265X Enthusiast Graphics with AMD Enduro™ Technology. for some reason its started overheating and shutting down (three year old) so i went to the local shop to fix it but when i got it back, i found my graphic card was missing as when i right clicked the desktop i cound see the setting of amd. so i downloaded the online software to detect and update the drivers but when i run it, it said hardware not found. so i was wondering where can i buy the same graphic card or little bit better for my laptop of amd.
You wouldn't have any video if the GPU was physically missing... unless the CPU is able.
If there are two separate chips controlling video it's possible that whoever worked on the computer disabled it in BIOS.
I believe this a driver problem something I had with my rx560x, for me it show radeon pro 460 or something like that.
So what I did was, I did a clean uninstall of all my drivers using a third party software called DDU (display driver
uninstaller). Then did a clean install of my drivers through acer's page for my laptop. In your case the toshiba
page for your laptop.
