Computer or processor is overheating









Make sure your PC/ laptop and processor is not overheating, check the heat sink or the CPU fan, Make sure the computer case is clean and fans are not obstructed. High heat temp can cause a significant decrease in computer performance, some processors will even lower the speed of the processor automatically to help compensate for the heat related issues/problems. 



Dust, dirt, and hair can also blocked the air flow, which can also cause a PC/ laptop to overheat. 









Memory upgrade









If you have a PC/ laptop for more than a year behind, surely your PC/ laptop will not meet the memory requirements for today. So we strongly suggest that a min. RAM of the PC/ laptop should have a 1GB of memory installed.
