Q: Heres the situation:
My friend who build systems all the time, and I decided to join a computer for me about 10 months ago. We plugged everything together, it worked and I was a proud father. I loved my system and I took care of her. Everything was great until this morning when she would not be enabled.
Now I discovered that the power had gone during the night since the microwave and other appliances blinking 12:00. My power bar does not have a switch flipped though. Can a power surge that my Power Bar not responding to the source of the problem?
Anyway, I understand that it is probably the power supply or the mobo. Heres the spec on them
Asus A8N-E Socket 939 Nvidia Nf4 Ultra Chipset
Antec Piano Sonata II case with a 450W SmartPower 2.0 ATX
If anyone can help me figure out what hardware is faulty I would be grateful. Suggestions, links, ideas – anything will help.
Re:Woo Hoo!
Success. I replaced the PSU and I'm back again.
Thanks for the help!

Instead of starting a new thread, I'm having a similar problem with my PSU or my mobo to blame
I assembled all my new parts right out of the box, plugged in my power cord and attempted to boot it up. Nothing happened except the mobo LED light comes on for about a couple seconds, the CPU fan sorta turns on full speed but seems to run at a low speed, and the PSU seems to be running also. I removed everything but what's needed to start the mobo and the same problem exists.
My hardware:
Gigabyte GA-965P-S3
Ultra V Series 500W PSU
C2D E6400 Stock Fan
Good manners dictate that you should start your own thread and not take over this one,
(known as hijacking)
Sure someone will help you out

Re:I'm pretty sure that it's the power supply. I've come across a few other articles that discuss a damaged PSU that emits a quiet humming. I'll be getting a new PSU over the next few days. I'll let you know how it turns out. Thanks a lot for the suggestions and feedback.
Re:Yep, most likely power supply
Re:After a Smart or TruePower is 2~3 years old the odds of it going bad are very high.
Open it up and find leaking Fuhjyyu capacitors. Google that brand name…Read

Re:High pitched hums generally mean a failing/damaged psu – there could many other causes too – so there is a possibility that the psu is damaged – see if you get another psu to test the system.

If the computer was off when this outage/spike happened, nothing should have been damaged. I wouldn't trust the surge protection of low end power strips, in fact it may have no protection at all. However, I have seen surges/spikes coming thru the broadband cable connections and zapping the network card, but rarely the mobo.
Try a different power point/strip.
I've got a wireless adapter, so it couldn't have received a surge through the broadband connection.
Re:Well, it's not the video card. I pulled that out and it still didn't boot.
I noticed that when the system is plugged in it makes a very, very quiet and high pitched electronic hum. I'm not sure whether it did this before. Does this indicate anything about the PSU?
Any help is appreciated
