I can't receive constant sound from my pc. I was having problems with electrical surges at my old house and had to move my pc often. So now, no sound comes out except when I play with the speaker plug going to the back of pc, once in a while it will let sound come thru. Also the same with the microphone. Is there anything I can do to correct this with out putting in another motherboard to replace these connectors. The computer store informed me that replacing the motherboard was my only hope.
Please help !!!! Thanks......

I gather from your post that your motherboard as on[board sound and that you occassionally get sound when jiggling the plug in the socket.

If this is so then the problem could be due to either a problem with the socket or the sound jack. the mostlikely is that the cable in the sound plug is damaged and just needs cutting short and a new plug put on. You can check this by borrowing a known good cable tec from a friend and trying it out.

If the socket is stuffed then you can either buy a replacement motherboard, or save a lot of money and get a better sound system by purchasing a sound card and installing it into your system and then disabling the on-board sound. this would free up system resources and give you more flexibility re sound quality whilst saving you money.

Some time ago I purchased a MIDI equipped accordion, was constantly having in/out signal problems, many thru links in double sided circuit boards involved. Very time consuming, requires patience. Cheaper than a new board, if it works.
I took a magnifying glass, well lit, 15 watt soldering iron in hand, and solder in the other. It is necessary to check both sides of the boards.
I temporarily solved the problem, for a while. I repeated the process again.

I am glad your home fix worked. I have seen problems where resoldering a joint on a motherboard has caused a heat problem with a nearby component, thus I do not recommend such actions unless there is no other alternative. For problems with on-board sound or video I usually spend $20 to $60, depending on quality wanted, and buy a sound or video card to plug in and turn off the on-board component. Even with the cheapest card available you usually get an upgrade in quality of sound or video. Also much safer.

There is a product in Australia called "Switch Cleaning Fluid." No doubt a similar product is available where you live. It has worked wonders for me with bad connections, and would certainly be worth a try. You just spray a little into the socket which is giving an erratic connection.
