First try shutting down you're system. Than turn the PS off at the rocker switch (Back of PS). Ground you're self by touching the the PS. Remove you're memory and re-seat it. Than boot the system.
Check the standby LED. See if it lights green.
Pull the cmos battery and check its voltage. Anything under 2.4 volts replace the battery. Normally the MB LED displays green. (Standby power).
This means the MB is maintaining / charging the cmos battery. If the battery can no longer maintain charge this will cause the MB LED to turn Red. Built into the mother board is a small switch. When the system is shut down the MB maintains power to the cmos. If the standby switch fails to function correctly the LED will turn Red. Lets hope the problem is the cmos battery. The internal switch can not be repaired.

Power button not turning computer on


this is most likely a short in a computer component, You need to unplug everything from the computer incl CPU, Memory, Add on Cards, Hdds, the lot, just have motherboard plugged in and push power, if it powers up (there won't be a pic but you will know it's working) start replacing parts one by one until it won't start and that is the faulty part. If it does nothing with just motherboard plugged in the motherboard is at fault and needs to be replaced, If you have had the motherboard out make sure no of the metal mounts in the case are shorting out anywhere under the motherboard as this will also cause the same fault.

My Acer will not stay on


The promblem is the motherboard, The laptop motherboard itself has overheat and a compacitor has become fried. You will need to get a new motherboard. Another promblem can be a short in the laptop, maybe a loose screw or something which is causing ground.

Your hard drive is bad. Take your windows disc and have it bootup on the disc, and do a windows repair option on the setup disc. Windows will tell if you have a bad drive or not.

Either the new power supply you purchased is not functioning correctly. But, assuming it is now that you are getting some form of power to your PC, it is very likely the motherboard. Whatever fried your old power supply (or it could have just been the power supply itself) most likely fried your motherboard in the process. Probably not the CPU since the MB can't even post.
