Detailed explanation-1: -User can hear fans spinning, but the computer does not start, and there are no beeps from the speaker. POST procedure is not executing. Faulty cabling or damaged or mis-seated CPU or other motherboard component needs to be replaced.
Detailed explanation-2: -Bad Power Supply The little brick-like metal case inside the desktop tower contains the power supply, and it houses a little fan of its own to keep cool. If this supply fails, the computer itself won’t power up, but the cooling fan may still run.
Detailed explanation-3: -Step 1: Check Your Cables Make sure any surge protector or power strip is correctly plugged into the outlet, and that the power switch is on. Plug in other devices to the power strip and confirm they are operating properly. Double-check that your PC’s power supply on/off switch is on.
Detailed explanation-4: -If you have a flat panel LCD monitor, unplug the monitor power cable, wait about 30 seconds, reconnect the cable and then turn on the monitor. This resets the electronics on the monitor. If the monitor has a detachable video cable, obtain a second monitor cable for testing purposes in case the cable is bad.
