I have a lenovo Z 51 with 8gb ram, 4gb amd radeon R9 M375 graphic card. Its only a year old laptop. So it started whn i ws playing wwe2k18 and the screen froze. No keys wer functional so used the hard boot. After restart all game wer not working. Games crashed and a dialog box said - gpu will not respond to more common..... So i uninstalled the amd software and reinstalled the latest one. Now my pc started freezing more often. I had to hard boot eveytime. Thn i reseted my laptop. Bt the problem is still there. What problem is it?? Any help will be appreciated. Also i installed a new motherboard 6 months ago.
