Hello, my laptop graphic card is Nvidia Geforce 820M, but laptop has also integrated Intel(R) HD Graphics 4600... So i have a problem, I've been playing Gta V with low graphics and it was lagging but it was working, but i stopped playing it for like a month, but yesterday i opened the game just for fun and suddenly after few mins playing bright color lasers appeared in game, like a lot of them going all directions, i immediately turned the game off and restarted computer and i thought its just simple problem, but today i was browsing web, watching movie but not playing any games and computer had no problems running it simple tasks, but when i opened another game(which doesnt require good gpu), those lasers where there, so i thought my gpu broke. I disabled my Geforce 820M and run game only using integrated card and there were no laser lines it was kinda working. So i need an answer is it that my Geforce burned down or there seems to be some sort of other problem. At first i thought that problem might be with electric installation in the dorm room im currently in,because the outlets are horrible here but i think thats stupid but worth a mention. Also can it be that my drivers became out of date?
