My computer had a power outage and now the computer won't turn on. I was told that he was probably my power supply was bad, so I went the Cheap Guys and purchased another power supply and put it in. The light on the computer turns on but nothing else does. The light didn't come on before with the other power supply only with the new one. Please help. Thanks.

Re: Computer won't turn on
Pull the battery out of you motherboard it will reset your bios leave the battery out for a couple minutes then when you put it back in boot up and it should go into bios use your arrows to select set defaults hit enter then reboot it should boot up then if not its possible you have a hard drive issue.
I had a an outside breaker blow while my Gateway 506gr was on. Once power was restored all I could get was the colling fans powered on. Had a blank screen and no sounds of the comp trying to rebbot. I did just as James suggested, pulling the battery from the motherboard and re-inserting it after a couple of minutes. The comp was perfect upon restart, I didn't have to do anything further to it, thanks!

I had an Emachines W3609 that did the same thing, I changed the 350-watt power supply with a 550-watt and it still shut off, even using the newer one. I thought just the first one was bad but I guess not. It had more than enough power to power it up but nothing. And it used to randomly restart at times and then just shut off. Try and get a new hard drive maybe that will help. Good luck!
If the computer won't start at all (no lights, no fans, no noise) then the power supply is probably bad. But first, just to be sure, check to see if it's plugged into the wall and the computer. Just in case the wall plug or power strip is bad, try another wall socket. A bad power supply is easy to replace. If you are handy with tools, just go to a store that sells computer parts (or go online) and buy one of the same type and swap it out.
When you press the power button, is there no life?
The PC may be set up for manual start instead of auto restart after power is restored.
Otherwise a surge may have blown the PSU.
Mine's not a Compaq but I'll research what the green light is. Could be a modem....
If your desktop computer went bang from the back of the computer and the burnt smell comes from the fan grill of the power supply then the switch mode power supply definitely failed. The bang and burning smell was probably one or more of the capacitors that has exploded inside the power supply. You can replace the switch mode power supply, make sure you purchase one that has the same total wattage or higher wattage. There is a chance that when the power supply failed it may have caused a voltage spike that could have damaged some other components. You won't know until you replace the faulty power supply.
The blue flashing light is probably on your power supply. I suspect that the power supply was subjected to a voltage surge during your power outage. It may have damaged your power supply (or possibly other components in your computer)
Try unplugging the power supply from the wall socket and leave it unplugged for at least 5 minutes. Then plug it in and see if your computer will turn on. If it will not, you require the assistance of a PC technician to test your power supply and computer.
You should connect a surge protector or UPS (Uninteruptable Power Supply) to your computer to prevent this from happening again.

The greenlight is probably the UPS [Uninterruptible Power Source]. If the computer was shut down by a normal windows shutdown and the UPS remained plugged into the 120 Volt line and the computer's power supply plugged into the UPS and the UPS NOT turned off, there would still be 5 volt standby voltage applied to the computer's motherboard. ATX type computers never go completely off unless the power supply is turned off or unplugged. That 5 volts would have to on steadily for the rest of the voltages from the supply to turn on. If there is a reset button or on off switch at the back where your power cord plugs in toggle it back and forth. You can also try disconnecting the power supply and holding the power button in for about 15 seconds to discharge power.Leave it unplugged for a few minutes. Then try powering it back up again. If those don't work then you might have a bad power supply. They are not hard to replace.
Hope it helps
Sounds like it could be the power supply was damaged from the power outage. If you have another PC you could pull the ATX power supply out and install it in the gateway and see if it boots up. Power supplies are fairly inexpensive so look for an aftermarket one...buying a replacement from Gateway will cost alot more. If the power supply turns out to be good then remove one device at a time the try to boot up. Sometimes a bad cd-rom drive or harddrive can cause a problem. My best guess it is the power supply.
power supply is probably shot and you are feeding a voltage way over what is needed. I have a dell that refused to operate one day. I went to www dot affordablesurplus dot com and found a 350 watt power supply with all the RIGHT plugs. Never had a problem since.
