I have a Compaq Presario SR 1318 NX with a ATX 300-12z Rev: BD HP P/N 5187-6114. While we had a power outage I had turned the computer off, when I tried to turn it back on I noticed a green blinking light on the back and the computer would not turn on. Does anyone have idea's as to what could be wrong with it? Do I need a new power supply?

Most computer testing facilities will test your current power supply for free. A replacement is very inexpensive to replace. Bestbuy, MicroCenter, small computer shops and buy replacemnent from Amazon.com, newegg.com.. Just make sure you have the correct information for your replacement. The model number on the power supply would be your best bet in most cases. Good luck and have a great day. I buy power supplies as low as $15 dollars Generic
The blinking light is telling you something about the PSU. First check any AC mains voltage select switches for proper setting. US should be 115. Second if you have a multimeter, you could test the PSU for voltage. Disconnect all power to all components. remove all components from the board including cpu, memory . Leave the PSU only plugged into the board. Press power. If the fan turns on then it's not the power supply. The brand power supply isn't the best, I've seen where you need to wait for 5-20 minutes for the blinking to stop, at which time it will fire up. Now, if it doesn't power up, then it's most likely the PSU.

Do yo have a volt meter or an atx psu tester? you can check voltage to see
If a power supply is bad, your pc will turn off or/and turn on and turn off. As long as your system is running without and shut downs your good.
However if your pc is turing off, I would change it as soon as you can. basically what is
happening, when you unplug everything there isn't much of a draw on power
so the light remains steady, but when you plug devices in there is a
draw and the PSU cannot deliver.
Hi. NO, *********** board is not fried. I am not sure what the problem is but I do know how to fix it. It is usually casued by power outages (even if you have UPS supply).
1. TAKE OUT THE ELECTRICITY LEAD TO THE COMPUTER. Look inside the computer and find the bunch of wires coming from the power supply unit (the box thing at the top with the fan and all those colouted wires!).
2. Find where these wires run into a plastic connector and plug into the mother board. Unplug it.
3. Now plug the electicity lead back into the computer. The light should now stay ON.
4. Plug in the connector again... and boot up. Leave it run a while to convince it!
5. Repeat this process if it does not work first time.
This should fix your problem . It works for me when I get this problem.
