Question about Gateway Emachine Bestec ATX-250-12E PS 250w Replacement Power Supply Part Number P/N 100744 (PSATX25012E) Power Supply
Both my son and I have E-Machine Model D2246 desktop computers. Both machines seem to have experienced a failure of their power supplies since neither machine will power up. Is this a common problem? My son's computer is completely dead and my machine will indicate power if the button is pushed in but does not start. I've ordered another power supply to test in these machines but I am worried that the mother boards may have been damaged and may not allow the machines to power up. Is there a problem with the motherboards on these machines? What is the protocol for testing?
E-machines are notorious for having weak power supplies. Although not impossible, it is unlikely the motherboards are damaged.
You may also look online for rebuilt power supplies that are beefed up from the originals.
Be sure you have a good surge suppressor and surge suppression on your phoneline if you use dialup. I also recommend surge suppression on your ethernet connection as well.

Power supply is normally first thing to go. Second most common is the motherboard. Sometimes one takes out the other. You can either replace power supply which is cheaper to do or if you want to test power supply that is an option. You can test the power supply with a paper clip. Although this tells you if the power supply is working or not, it still doesn't tell you if motherboard is good. If you plug in new power supply and still doesn't work, then most likely board is bad. You can see how to do paper clip test here:
