So this problem has been puzzling me for the past couple of weeks. This all started by me trying to unscrew an overstripped screw on th CPU fan which I believed caused a short. The problem is I don't know whether it's the CPU or mobo. The computer will cycle on and off at increments of 3 seconds. I have replaced the psu with no avail. I also noticed whenever the 12 volt power connector is in the computer will do what is stated above. Any help is appreciated

I have tried resetting bios and taken out battery.

First I would remove and reinstall the CPU. If that doesn't help, have the CPU tested and you'll know for sure if it's the motherboard or not.

Best bet is to re-install the rams and check all wired connections. then look at your power supply unti's connections. you never know when you might have accidentally loosened anything.
