Just recently, I installed a nvidia geforce gt 710 because my previous graphics card got damaged and lines kept appearing on my screen. The gtx 710 fixed that problem however after playing games for a few mins, the screen just freezes. I checked the power requirements for the gt and the min. was 300. My psu is 375. Sometimes, an error message stating "Video_scheduler_internal_error" shows up and restarts the pc. Can someone please help!
