My computer is 1 year old. The computer does not switch on. I take out the smps and connect with another mother board it works and then again I connect same smps with my previous motherboard it open after sometimes in the morning period after taking out the 24 pin and 4 pins of cpu and again I insert in motherboard 24 and cpu pin simetimes it comes and when it gets on the computer. It works till night unless and until I shut down the computer. When I wake early in morning it does not open and again I have to insert the pin and take out to work after lots of scratching with tester just putting on topog shutdown pin
