Hey

For a few days ive been getting blue screens pretty much everytime i start to play something or watch movies. Ive had this problem before but then it just suddently pretty much fixed itself. Doesnt usually happen while just browsing internet.
Would appreciate if someone could check the logs,

Ran memtest and found some errors on 2 diff sticks, third stick passed. Pc was working fine for several hours but then got the "display driver has stopped responding..." error twice and bsod soon after that. Updated some drivers and installed all windows updates. Updated SF log,
