Re: mother board

Mitsuman, and guest, check your power supply. Sounds like a voltage rail is weak or has gone south for the winter. Electrolytic capacitors break down, and there was a rash of bad capacitors from a capacitor maker. Seems they had stolen receipe for the electrolytic paste, and it developed gas after a time. The little cans popped open from the gas! lol!

Re: mother board

If the motherboard came with on-board video and you have a black screen, the only thing you can check is the monitor itself by swapping the monitor out with one you know works. If you do this and still have a black screen, then the problem is the on-board video. There is no way to repair that problem as it is built into the motherboard. If you put a separate video card in and still have black screen, this happens because you have to change a setting in the computer's BIOS for the computer to know it has to use the video card you put in instead of the on-board video. Unfortunately, you cannot change the BIOS setting without seeing what you are doing on the screen (that does not work). It's time to buy a new computer. Replacing motherboards is hardly worth the cost -- and next time do not get a computer with an on-board video (other on-board components are fine).

Computer is getting power and fan is running will not turn on at all??

Its a minor problem. loose the system, remove the memory clean it and put it on again. If it's not still working, Check the power pack wire, if it is well connected to the mother board and also remove, clean and put back the processor if possible.

Then check the wire that connected the system to the monitor if it is well connected and also check the VGA from the inside of the system.

I with all these the system should bring a display.

Take care.

I have a HP PC. the compouter does not boot. A vendor tested it and said the sound card is gone bad. The sound card is on the motherboard. wat to do?

Unless you love this computer you have to take this mother board to the manufactuer for componant repair.
Could be anything. Diode issue or transister unless you have the schematics for this item you can fix it your self and test, however if you don't love this mother board as you do... might just have to replace the mother board
