Hi, I have a problem … laptop screen is blinking and cut the picture frequently …then I restarted the laptop…works fine but the fan spinning very fast and causes heat also…then after 3 days it suddenly shutdownn while i am surfing net…I started the laptop 2-3times power is on but SCREEN IS BLACK…why what is the issue….and I have cleaned the fan still it blows hot air why?… Please give me solution….please…soon as possible…

Are the slots where fresh air is entering the computer clean? The symptoms are that those of the CPU or GPU are getting to hot and the PC is shutting down.
