You should try to know the exact moment when your computer just STOPS responding, such as: if it happens often while your computer is at hard work (like at the time of playing games) then you should check the issues related to heat. The intake fan of your computer might have failed, or perhaps the vent might have been blocked. Also ensure that the heat sink of CPU is making GOOD contact with the processor’s top part and you must also ensure that the fan of the CPU is clean. In case the problem happens randomly then scan your computer because there might be a virus behind all these problems. You should also check the driver software if they are up to DATE or not. If again the problem is still there then check the HARDWARE, RAM of your computer or power supply might have problem.
