Monitor not displaying anything because of CPU

mohityenugwar there is nothing you can do. If your processor has failed the only way to get things working, is by replacing the processor.

"There is no realistic way to repair a processor itself. The only viable solution is to replace it. You should be able to find used Phenom x2/3/4s fairly cheap online.

Also, most AMD FX series processors do not include integrated video capabilities. These CPUs were designed for gaming systems with dedicated graphics cards. There is a possibility there is, in fact, nothing wrong with the processor."

U can change d processor can't b repair

It could also be the motherboard. Try the CPU on a different motherboard and see whether you get anything. Vice versa, you could also try a different CPU on the same motherboard. My guess is that most of the time, it's the motherboard.
