Windows 7: Power Outage.. now computer won't turn on

Power Outage.. now computer won't turn on

Okay, so.

I know everyone has heard this scenario, and I have done a good amount of time on google searching for an answer, and have yet to come across something that helped.

What happened:

Overnight on Tuesday we had a pretty wicked thunderstorm which knocked our power out when I was sleeping (clocks reset, etc gave it away). When I woke up, my computer was off. No problem, I thought, that is normal. I go over to boot it up.. nothing. No LED lights, no fan spin, no beeps, no NOTHING.

What I've done:

I have unplugged and switched off my computer and left it all day, came back after work, plugged it in, still nothing. I have tried a different outlet, still nothing. I have flashed the bios for fun, still nothing. I've checked and rechecked all of the cables (which shouldn't be necessary, the computer didn't move), and they all are correct and in place (I've reseated them too).

Now, I know what you are all going to say : "Do you have a surge protector?" Yes. Yes I do. I think it just failed or something.

Also, I know you will tell me that my power supply is most likely fried, and in all honesty, you are probably right. I don't own a tester, so I will probably have to run to Best Buy or something with just my power supply to have the Geek Squad test it for me.

What am I looking for? Any. Other. Possible. Solution.

As I said, I am going to test my power supply when I get time, and no, I do not have a spare one lying around/other PC to test it with.

Thanks for any/all input

How did you flash the bios if it won't turn on?

Some surge protectors only work a limited number of times (I don't know why, I've just seen some that say it on the packaging/protector itself).

I've got to wonder how you "flashed the BIOS" when you cannot get the computer to turn on. Sounds to be like your power supply or your motherboard has died.

Sorry, wrong terminology.. I just removed the CMOS battery for a few minutes, its solved random things for me before We just call it flashing the BIOS around here to make it sound like we are doing something impressive, sorry for the confusion.

That's an operation that requires power.

Without having access to another power supply, this is pretty hard to test on your own. I think you are going to have to take it somewhere and have it tested. I would think a small computer shop would test it for free as long as you are going to buy a replacement power supply from them if yours turns out bad.

If it was a surge, it could be a number of things that got hit.
PSU, MOBO, CPU ...
Maybe just the PSU

I agree, have it checked.

But I would think, if the power supply itself isnt powering up, or fan spinning it very well may be dead.

Do you have any diagnostic/bench testing switches on your board?

Maybe try to bypass the power switch on the case all together, and power up from the board itself .. If it has a button for it on the board.

There aren't any switches, but the first thing I am doing when I get home tonight is taking my screw driver and placing it in between the two links where the power switch cable plugs in, for my motherboard as far as I know that's the only way to bypass the switch

If you have some spare wire, that would be better than a screw driver. Not all of them make the best conductors.

you can try disconnecting the power cords to extra devices you don't need that your power supply is supplying power to...obviously leave the power cord to the mobo/hd.
