ok my puters power supply fan was going out so i tryed to clean it with canned air . Plugged puter back in and on pushing the power button fan makes awful noise puter shuts down.Puter used a atx 20 pin power supply so bought a 24/20 pin replacement same wattage (400).Put it in today now puter powers up but no monitor??? one thing i did notice the original plugin had a connecter in every space on the connecter ,the new one has one little square with no wire in it?
so\any help appreciated trying to learn here and THANKYOU ok i edited this post to say i seem to have found my problem. my power supply has a -5v connection which is optional in later motherboards soooo i need to find a power supply w/the -5v connection any suggestions?????????
