I am having trouble getting my pc to start up. It seems like either the power supply or motherboard is dead. When i try to turn it on, the green light on the motherboard turns on but nothing else happens. The power supply fan doesn't turn on, nor does the hard drive or any other fans. Does anyone have any idea what is going on? Thank you very much for your help.

Hello and welcome to PC Help Forum.

Firstly make sure power cord is pushed fully in?

Open up the PC and check all cables and connections are fully plugged in,that nothing has come loose inside.

Okay, the power supply is firmly plugged into the wall so I don't think that is the problem. On the inside, the power supply seems to be plugged into the following things: the cd drives, the floppy drive, the zip disk drive, the hard drive, the mother board, the fan (yes, only one besides the power supply fan and cpu fan). That fan is aimed directly at the mother board in between the graphics and sound card. Is there anything else that the power supply should plug in to? Thanks a lot.

It could be failed power supply?

Do you have a power supply you could try?

Yes you should have either a 20 pin or 24 pin power connection on the motherboard with a power supply lead going into it.

They may look connected just check they are pushed firmly in.

It is plugged into the mother board I think. Is a lead different from a plug? I have something with 20 wires plugged into the mother board. I don't think i have a spare anywhere. Should i go ahead and buy a new one or might that not be the problem?

Yes the usaly black lead from plug goes into back of tower.

It could be prosessor?

But proberly power supply or loose connection some were.
