Windows 7: Old PC does not post

Old PC does not post

Ok so my friend gave me his old PC and said it wasn't working so I decided to take a look at it. He had said that nothing was showing up on the monitor when he turned it on so I assumed the on board graphics were probably shot. So first thing I did was try using a different working gpu, but still no response from the monitor. Next thing I tried was using a better psu; the fan still was not spinning and still no signal. From here I assumed the mobo was dead, but not 100% sure as the fans plugged in were still spinning and the hdd was still able to run. Also checked if the cmos battery was still good and it was. My next step was to check if the mobo would give me any beep codes so I removed everything buy the CPU and the psu as well as the on button, and to my surprise it gave my no response. Not sure if I just don't have the speaker plugged in or if it doesn't have one.

Now current day the machine doesn't post what so ever and I'm really stumped as to if it is the mobo or something else is the culprit.

The monitor is confirmed working.

Try CMOS reset if you haven't yet. You should get a PC speaker. You may even have one from your own PC case, you left lying somewhere. I guess they are a couple of bucks if you don't have one.

Ok so I plugged a set of speakers into the audio jack and it's giving me nothing. I've tried the cmos reset, but I'm not sure if it's even in the original position. Now my friend said he didn't really do anything to this PC but you can never be to sure.

Nope, it won't work like that, a PC speaker is two cables and a little speaker that you attach to a little plug (usually near where the front panel cables are connected) on the motherboard.

It is used to diagnose BIOS beep codes during POST (Power-On-Self-Test). Computer POST and beep codes

Ok so it seems the mobo has one attached to it (didn't realize till I went out and bought one) but it doesnt seem to be giving any beep codes.

Are the fans start working? Try with the other speaker too just in case old one is damaged.

Still no go, remove everything but the CPU and see if you get any beeps.

Yea it powers CPU fan plus other case Fan. Now I'm not to sure where to plug the other speaker into. There is a 3 pin connector labelled spdif02, and I assume it should go there but correct me if I'm wrong.

Nope, spdif is digital audio, check where the twisted colorful cables plugged into the motherboard.

Those braided cables are fpanel stuff. Nothing really around it except for a 3 pin fan header. Could you link a pic? First time dealing with a mobo speaker

There is a connecter labeled j1394_1.

Is the mobo speaker connecter 2 pin or 4 pin?

Would it be in the Fdd1?
