Hello!

I shipped a computer to my boyfriend. It was working, installed the OS, all sorts of happy stuff. Packed it up, sent it to him, and now it's not working. When he turns it on, the light on the front flashes, the chassis fan runs, and the cpu fan goes on and off with the flashing on the front of the computer. I've had him test the memory, and make sure that the jumpers aren't loose and the video card and stuff aren't loose. I can't think of what else to look for (on account that he's screaming in my ear that this is bullbleep), so can someone give me some ideas?

Check your power connections on the motherboard. Also make sure that the RAM is seated properly.

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

Chasis fan runs while cpu fan goes blink blink, it means the power supply is damaged.

Hm. That was a brand new PSU too.

I tried having the boy check all his connections too, and it seems he bent a pin on the power led connection on the motherboard. That shouldn't affect anything, should it?

When I get out there I'll try a few things, buy a new psu and hook it all in and see if it works.

I am actually at the computer now. I put in a new psu, started it and nothing. The light on the motherboard comes on. Neither of the fans start. The light on the front doesn't turn on, and I'm pretty sure I've got that jumpered correctly. Help?

There should be 2 plugs going to the motherboard. Are they both connected?

Recheck the new power supply and make sure it's OK

The purpose of this procedure is to bypass the motherboard to test the PSU.

Caution:
This procedure will involve working with live 12VDC electrical potentials which if handled improperly may lead to electrical shock. Proper precautions should also be taken to prevent electrostatic discharges (ESDs) within the case of the computer. For safety purposes please follow the instructions step by step.

First, shutdown your computer. Then unplug the power cable going into your computer.

Once you have opened the case, touch the metal of the case to discharge any static electricity.

The connector of the PSU which connects to the motherboard is readily recognizable by the number of wires in the bundle. To disconnect it you will need to press on the plastic clip to disengage it and then pull the connector up and away from the motherboard. Please take notice of the location of the locking tab and the notch on the socket of the motherboard, this will only connect one way as it is keyed. This wire bundle will have a memory of the way it has been installed and will want to bend back that direction, you may have to play around with it to find a position that the connector will stay in the same position while you run the test.

From the top left to right the pins are 13-24, the bottom from left to right are 1-12.


Please notice that there are PSUs with 24 pin and 20 pin connectors, the location of the green wire in the 24 pin connector is #16, and the green wire in the 20 pin connector is #14. If you look at the connector with socket side facing you and the clip on the top the number one pin will be on the bottom left corner. This makes the pin out for the 24 pin connector from left to right 13-24 on top, and 1-12 on the bottom. The pin out for the 20 pin connector from left to right is 11-20 on top , and 1-10 on the bottom. If you look at the connectors you notice that these are sockets that fit over the pins on the motherboard where the PSU cable attaches, this is where you will place the jumper. For a jumper you will need a piece of solid wire about the size of a paper clip (20-22 awg), preferably a wire with insulation. It will need to be large enough to fit firmly into the socket so that it will not need to be held in place while testing. You are at risk of electrical shock if you are holding the jumper when you power up the PSU. Insert one end of the jumper into the socket of the Green wire, and insert the other end into the socket of any Black wire.

Once the jumper is in place plug the cord back in. If the PSU is working properly the case fans, optical drives, hdds, and LEDs should power up and remain on. I would suggest that you not leave this connected any longer than is necessary for safety purposes.

To reconnect the 20/4 pin connector unplug the power cord, remove the jumper, and reconnect the connector. Take a moment at this time to make sure that nothing has been dislodged inside the case.



Other than that all I can suggest is to try it outside the case on the bench. First just have the memory installed, then add things one at a time

I have only the memory, cpu and heatsink and fan for the cpu in. The fan is spinning and stopping and the light on the front is flickering.

I plugged the cpu fan in and now both the chassis fan and the cpu fan is running. They go for a few seconds and then stop and then start again, which it was doing when the boy received the computer.

There's the possibility that it was dropped when it was shipped and the motherboard could be damaged
