I have a Notebook / Laptop Toshiba 15.6'' Satellite S50-B-14Z, HD, Procesor Intel® Core™ i7-5500U 2.4GHz Broadwell, 8GB, 1TB, Radeon R7 M260 2GB and I constantly have page_fault_in_nonpaged_area, atikmdag.sys, no matter what i'm doing. From time to time, the system is freezing and the only way to restart is from power button.
I've reinstalled the system several times during last month and I have blue screen or freezing few times per day with Windows 8.1 or Windows 10. This is happening in many scenarios like using internet explorer, updating Windows, windows explorer, games (CSGO), etc. Currently I have Windows 10 with all updates, and no other software and the problems persists. I went to service and the answer is "Harware is OK".
I've tried multiple things, like testing memory (memtest86+ or windows diag memory), update drivers to last version.
Any suggestions ?
