Problem with the P4P800-e mobo; can't power it up

CarlosTheJackal · 01-07-2006, 09:27 AM

After coming home one day, I couldn't turn on my computer. It has been recently put together and it has been fine up until now. I don't even get the LED standby signal. Is this a problem with my PSU or mobo? Any help would be greatly appreciated.

Sudden death, and no LED's tells me it's probably the power supply. There is a rare possibility the power supply has "locked up" meaning the oscillator that controls the internal functions has stopped. Sometimes this can be restarted by disconnecting the AC line for a period of time so all internal voltages dissipate. If you try this, leave it disconnected for an hour or so, and then reconnect. See if that brings it back up. But if it does, I would expect it to happen again. Also check that 115/230 switch on the power supply, next to the power cord. Make sure it's set correctly.

None of the above has worked; so is my PSU faulty or is it the accident-prone motherboard I bought?

your P4P800-E is no accident prone motherboard >>>>> there are 3 or four of us here running this board and NONE have had problems >>>> I have sold over 17 of them myself >>>>> no clunkers yet !!

I would look to the PSU what make and model PSU is it ??????

I concur, no LED = probable bad PSU. It could be the mobo but before tearing into it I would try a good quality PSU like an Enermax or Antec at 500 + watts.

What make and wattage is your PSU?

Is it a generic PSU that comes with the Case?
