Power problem

When powering up, the fan on the mobo moves minutely, the power light on the front of the case is on, the PSU fan does not spin, the system does not boot up.If I take the PSU out and do the paper clip trick the PSU fan spins. Can any one help here? :confused:
 
Seems like you just need a new PSU. Your mobo fan is just getting a little pulse or something but thats it. Is it an OEM case...could be a diag light that would tell you exacty what the problem is. But it seems like a PSU failure. I wouldn't keep trying it.

If it works with the paperclip hack then its not the psu.

The motherboard is damaged - try clearing the cmos.

The psu is not receiving the 'mobo - good' signal and therefore not turning on.

The paper clip simply bypasses this. Your mobo is stuffed or cpu pins bent.
 
Good point, I hadn't realized that...I was under the impression that doing that bypassed a lot of the power it needed to start the pc. I had done it with an old dell but the psu was actually going, I guess that was just a coincidence.
 
Could be a few things. The paper clip means nothing except the power supply is not completely dead. It puts no load on it. Look on the power supply and see the make and model.
 
Thank you. it would appear that the mobo has gone as cleared the cmos but no change in the problem, even after a new CPU installed.
