Newly built PC: Turn it on, but (almost) nothing happens

[Divideby0]

I just built a new PC. I installed all the components as per the manuals, but it refuses to power on.

:mad: When i power on. All the fans get a bit of power (including the vCard and MoBo Chipset) for like 1/10th of a second and nothing happens. There is no beep, no BIOS. no nothing. :mad:

I am in the process of reseating the RAM, vCard, and the Processor. Is there a well-known cause for this behavior?

I tried this without a keyboard or mouse connected...but i dont think thats it.

AMD Athlon XP 3200+,
MB MSI K7N2 Delta,
1GB DDR Mushkin,
vCard MSI FX5600XT GeForce,
HD WD Raptor 36GB 10,000rpm ATA
400W power supply

You mean your fans power up and then stop almost immediately?

Try clearing your cmos.

No beeps is very bad. Double check you have your motherboard standoffs installed right, and that the board is not shorting. I am guessing the board is dead.

RCX, your description is exactly what happens. All my fans "jump" but everything stays dead.

lemme see if i can find the jumpers to clear the CMOS and try that...

make sure you have a fan connected to the cpu header as some boards wont boot if there is no fan or if the fans rpm is to slow

Think more basic. Almost all ATX boards give that 'jump' of power when you plug in the AC or flip the switch on the back of the power supply. I'm guessing that you don't have the power switch from the case on the proper two (2) pins on the MB. Double check that. I hope that's all.

Yup, same thing happened to me some time back, the fix for me was to replace the PSU, although YMMV.

If none of the above suggestions work, and you have access to an extra PSU, try replacing the one in your machine.

Good Luck

Yeah, it was the front swiches were not connected fully. Don256us, you were right. You get a cookie.

Im still a little green at this PC building thing.

Thanks for the response. It's nice to know what worked and what didn't.

I'm glad to hear that it was a simple fix. It's always the little things that trip me up.
