Hello. Im posting this thread because i can not play any games anymore. Doesnt matter which game i start (sc2, csgo, league) my computer will not use my Nvidia graphics card. I see this by the low fps (12 fps) ingame, and on the MSI afterburner screen, where the gpu usage is 0% when ingame. I have tried looking in nvidia control panel and saw that its normal. Meaning that its supposed to use the nvidia card in the games. It happened after i one day started the PC, and it was very slow and sluggish. I of course after that ran scans with malwarebytes, avast and windows defender, and it cleared some small stuff out. I dont know what to do anymore, since i thought the problem was in nvidia control panel. I got an intel hd graphics 2000/4000 in the cpu which i suppose the PC is using.
My PC is
i5-2320 GTX 555 8gb ram windows 7
