Hello , i dont know what to do , the pc is brand new , components are few days old and im tired to call for suport and have them parts changed couse , literaly they changed every component in computer and they dont know what to do , i can do basic things with computer no problem but when i play a game , it shows 240fps and after few mins the comp freezes , and no its not a heat issue already checked but when i cap it at 30 fps it works smoothly , the comp specs are Intel core i5 4440 3,1ghz quad core , ram 8G dd3 , nvidia geforce GTX 550 Ti .. At 1st they changed HDD , ram and powersupply , then graphics card , cpu , motherboard . And they seem cant find the problem . Am i stuck now for always using some sort of fps capper or what ?
