A transformer down the street blew and knocked out power to my street. I didn't have time to check the pc before I had to leave for work but when I came home, the green power indicator light on the back was flashing and a rythmic popping noise was coming from the speakers. The computer won't turn on. Is my mother board fried?
Its the power supply, about $50-$60 retail, depending on where you get the part.
Worst case senario, your motherboard is fried, which would mean that it can be at least $400 to get it back up and running. If that's the case, I would recommend a new PC, given that most mid-end systems begin at that price mark.

well, there is probably a reason that it was on the street. Was it sealed, probably not?... so, you brought RAM...well, most PC's will power on and Beep to tell you there is an Issue with the RAM. This sounds like there is a Motherboard or Power Supply issue. No point in investing in a Harddrive. Just put it back where u found it and return the RAM asap. Or get someone a Techie to test the Power Supply and the Mother board!
the Power transformer has diferent outputs, +5V,-5V,3V,12V and so on.., but has a standby output a low power 5v to power button function.
Your PC have Power supply Defective,
so your must find a usual spare power supply on the market, compatibilty as 115V input and more of 350W power, to have stabilty.
computer abruptly shutting down does not have anything to do with hdd errors unless it tell you there was hard disk error
if computer shuts down in like a second or two, you might have a problem with the power supply unit, or the power cord that goes to the computer is loose in the tower or on the wall socket.
if the computer shuts down normally i.e. windows displaying "windows is shutting down" massage that you would get when you normally shut down pc...then you might wanna check your power plan option from the control panel. disable any hibernation/shut down options. go to control panel, go to power option, go to edit this power option.. you should see if you have selected to shut down the computer after a given time...select this to never and it may solve the problem.
you have to change your smps .
It is aquare box on back top side of CPU.
