Power went out in my room. Now PC won't turn on.

post #1 of 26
Thread Starter 
Yesterday I lost power in all the outlets in my room. The outlets in the rest of the house never lost power. I had my PC and other electronics connected with a surge protector. There was no storm so I don't know what caused this. At the time it shut off, I was playing Sonic Generations. Today those outlets still aren't working for anything so I'm using an extension cord on my surge protector to a working outlet. Everything except my PC is still working through the extension cord.

When I press the PC's power button there are no lights, and no fans or noise come on. I don't have another power supply that's powerful enough for my PC so I haven't been able to test it with another one. I did connect the power supply to an older PC that doesn't have a CPU to see if it could make any lights or noise come on, but nothing came on. With that older PC's power supply, the PC without a CPU does make a buzzing sound and light up. My PC specs are:

Windows 7 Ultimate 64
4GB DDR2 800MHz RAM
Intel Core 2 Quad 9550 @2.83GHz
Radeon HD4870 512MB
Seagate 640GB 7200 RPM hard drive
OCZ600SXS 600 watt power supply
Asus P5Q Pro Motherboard

Nothing is overclocked. I don't smell anything burnt in my PC, but I didn't try to smell it right after it happened. I've tried removing the battery from the motherboard and putting it back in, tried different power cords, and tried turning on the PC with a flathead screwdriver touching the pins on the motherboard, but nothing made a difference. Do I need a new power supply and if so which one?

You probably popped the breaker, lol. Go to your house's breaker panel (usually in the garage or laundry room), should be metal and have a bunch of switches inside. One of those should be in a different direction and be labeled for whatever that room is, just flip it back.

As for the PC. I've never known popping the breaker to kill the computer, but it could have been a short circuit in the power supply that took out the power. Sounds like your PSU is dead. It might have killed other components with it, so be prepared.

I'd recommend a Seasonic power supply if you can afford it as they are the top-of-the-line. Otherwise, I don't have an exact recommendation.

Kicked a breaker. Go to your breaker box and flip the switch that turned off for one of the bedrooms. Something was drawing too much current off of one outlet (you don't have a mini fridge and your computer plugged in to the same outlet do you?)

Have you tried plugging your computer into a different outlet? A power outage shouldn't fry components

Try to balance your loads on each outlet to prevent this from happening in the future

Didn't work with other, working, outlets?

Sounds like this happened. Do you have a friend nearby with a pc? Try going to his/her house and start swapping hardware to see what works and what does't.

If your replacement psu, on a working outlet, "kind of" turns the pc on, your in for a rough night, based on my experience on carrying cases around and waking up techy friends in the middle of the night.

I checked the breaker switches, but don't see just one switched differently from the others. There are two rows of them and a main one on top of those. The ones on the left are all switched to the right and the ones on right are all switched to the left and the main one is switched to the left.
The things I've had connected to one outlet with a surge protector are my PC, my 57 inch CRT HDTV which I use as my monitor, my Wii, my GameCube, and the receiver to my 5.1 sound system. I've had things setup like this for 3 years now and never had a problem like this before. The only thing I've recently done differently is playing Sonic Generations over the past couple weeks. But I have played it a lot in the past two weeks without a problem and while having much more programs running in the background than I did when the power went out. I rarely ever use the other outlets in my room unless I'm charging batteries.

I know the outlet I currently have the PC connected to is working because it is powering my other electronics through a surge protector; only my PC won't turn on. I'm posting this on my Wii's internet channel using the same outlet and surge protector that my PC isn't working from.

Unfortunately I don't have anyone at the moment that I can borrow PC components from. And no, I'm not in New York.

I searched on Google for others who had a problem like this before posting this topic and some were able to fix it by replacing the power supply which is one reason I'm thinking I might need a new one.

connect the power supply to a single fan and turn it on. Or if you have an multimeter, just test your your psu that way.

I connected 2 old power supplies and my current power supply to the old PC one at a time. I sat the old PC next to my current PC and connected a power cord to one of my current PC's fans then turned on the power of my old PC. The two older power supplies made the fan in my new PC turn on, but my current 600W power supply did nothing. So does this mean my power supply is definitely broken? Or is it just not compatible with my older PC? Both the older power supplies came with prebuilts and are under 300W and without the extra 4 pin connector. The motherboard in the old PC also doesn't take the extra 4 pin connector, so with my 600W power supply I just left the 4 pin unplugged.

Sounds like your psu is broken...what do you have in your new pc? are you sure the 300W psu's are not enough to power it?

I put my PC's specs in my first post. The newegg power supply calculator recommended 483 watts for my PC. The two old ones I have are 250 watts and below. The one I had been using on my current PC that seems to be broken is 600W. My PC's motherboard needs the extra four pin connector and the two old power supplies don't have one.
