|The case & everything in it is known as a computer, not a CPU. A processor is a CPU. Your CPU is an "Intel DC". You have a hardware problem, not a CPU problem.|
Since you called your power supply an SMPS, that means you're probably from India. India is notorious for having cheap/garbage power supplies. That is what you should be looking at. Buy a brand name replacement (Antec, Cooler Master, Corsair, Thermaltake, etc) & be prepared to pay for quality. Stay away from garbage like iBall, Hytec, PowerSafe, Zebronics, etc.
