Dear Sir, I have a Desktop PC. In CPU, I have Asus Motherboard. Last time, I have shutdown my pc regularly.. But after few day, when i started the pc, I pressed the power button (Blue Light) of CPU, it is glow and showed me ON. But No Display on Monitor (Its means no signal transfer to monitor). When I have Cheked it, i was shown a green light glow brightly on motherboard and Cooling system was worked regularly.. 2nd thing was a red led light (behind the power button of CPU) glow in starting of CPU after few second it was turn off and not work regularly...when i pressed power button again the CPU was turned off..

Kindly help me in this matter to troubleshoot my pc.

A no boot/POST after power on could be any number of problems. Had you been having random crashes and reboots (PC will shut off and reboot itself)? Are you getting blue screens? Have you had any beep codes? Are you running a graphics card? When the lights turn on (showing the components are receiving power), it could be a problem with the power supply not providing enough voltage to run the system. It could be a problem with the CPU itself. CPU's rarely die randomly, but it's possible. A dead CPU will cause a no boot and no picture on the monitor, but the fans will spin and the lights will turn on.
