Presario S5314 St won't power up and the fans don't work
The machine will not power up when power button is turned on. Green light at back blinks and the fans do not come on. I removed the power supply from the mother board and plug it into the wall, the fan still did not turn on.

Remove the Power Cord, Open the Case and remove one of thememory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x onit with an ink pen. If it fails to boot then move the chip to the nextmemory slot and try rebooting. If it fails take the chip out and set itaside, then put the other chip in and try booting it in both slots. If itboots, just to verify that the chip set aside is bad, mark an x on it and putit into the open memory chip slot and try booting.
Sounds like the power supply has failed. That's where you plug the power wire into it. You could try opening the case and re-seating the main plug connector on the mother board. This is the big bunch of wires that ends in a 24 pin plug attached to the main board.
(See if you can borrow a power supply from a handy family member?) http://pcsupport.about.com/od/toolsofthetrade/f/powersupplytest.htm
Do you hear the harddrive start up? When you push the power button (or switch on the back) do the lights go out? If you hear fan running and hard drive start up then the computer itself might be on but the monitor isn't. Check the power to the monitor, the connection between monitor and computer to make sure they are all on and connected.
If you don' t hear the fan running then you have other problems. Any blinking lights would indicate something is getting power. I'm assuming the computer was working before the power button was pushed... If the monitor is actually working, you could hook up another monitor to check too then you have other problems but need more info to know what that could be.
would need to know the answer to the above questions as well as if it was working before, what was done, what changed between it working and this problem. Also what age the machine etc.
This normally means that the computer is in standby mode all you need to do is press the power button. If this does not work then hold the power button in for about 10 seconds until the computer turns off then wait a further 10 seconds and turn back on and boot normally.
Please let me know it this works and please rate me. Once you booted normally set the power options within control panel not to go into standby.
