Motherboard has power, but won't boot.

Specs: Windows Vista
I just put together a new system with a intel core i5 and 4gb ddr3 ram. Tonight is the first night i'm trying to get everything going (I was waiting on a copy of Windows 7). I plugged in the power supply and the fans spin about one revolution then stop. The led on the motherboard indicates power, but it doesn't go.

I unplugged all of the components except the cpu fan and tried again and it did the same thing. Everything is brand new so I wouldn't think anything is bad. I've double checked to make sure things are connected properly. Any ideas? Am I missing something? Thanks guys!

It also might help to know that it only does this when I unplug the PSU and plug it back in. Otherwise I get no response from anything with the power buttons.

It sounds like you bought a cheapazz power supply. It also sounds like you threw all the hardware in the case without benchtesting it 1st. Both are mistakes.

The power supply is an ultra lsp 550 watt unit, I would think that could run a few fans a hard drive and a graphics card. Now, do you have any actual advice that could help me?

The advice is hidden in my comments. If you're sure it's not the power supply & you didn't benchtest before assembling everything in the case, rip ALL the hardware out of the case & start over...this time, do it right.

i had the same problem on the 25/9 (my birthday) when i realised by mobo was touching the case, the second time due to my idiocy i hooked it all up but didnt press the switch lol. ANYWAY i got it the third time. BTW you should have bench tested them first.

"The power supply is an ultra lsp 550 watt unit, I would think that could run a few fans a hard drive and a graphics card." Actually, that would depend on what the graphics card is. For example, if it's a GTX 295, say, then it might not be sufficient. How many volts on the +12V rail ?

I had the same problem with mine and it was simply a dead CMOS battery. Take the battery out and take it to any walmart jewelry department and you can get 2 of them for $5.00. I took the battery out of my watch and plugged it in to the mobo and every thing was fine. Thats all a CMOS battery is, is a big watch battery but you want to get the same size so bring it in so they can get you the right one.
