Power Supply

Power supply is one of the important in your casing. This is how I check a power supply is good or not.

 1). Find a wire; remove copper from your wire.

 2). Unplug a power supply connector from your motherboard.

 3). from the power supply connector you can see the green wire, that wire is only one from the power supply connector.

 4). Put the wire into the green wire slot and the other part of your wire put it into the black wire slot. You can put whatever slot of black wire.

                This is how I test power supply. 

How to check alert sound from the motherboard?

1). checks your VGA (Video Graphic Adapter) from the back of your casing. I told you to check VGA from the back of your casing because if your VGA is onboard, you don’t need to worry about it. You just need to check memory. Most of the alert sound is happen by VGA and Memory. If your VGA is AGP card or PC Express card, you need to check two things from your motherboard. They are VGA and Memory.

2). When you start to open your computer and then you can hear the alert sound. You need to know what sound is that. For my experience, if the alert sound is long for one time, it is VGA error. If the alert sound is short for one time, it is Memory. When I was in Myanmar, I work as technician; I have met a lot of display error. Most are happen by VGA and Memory.

3).So above this error, if your meet at your environment, you can do what I mention in below.

                VGA alert sound error

                                1). First remove your VGA (Video Graphic Adapter) card from your mother board.

                                2). Clean your VGA card and Slot with brush.

                                3). Insert your VGA card into the slot and make sure VGA card is not loose. Sometimes VGA card is loose and it does not display.

                This can be fixed VGA alert sound error.

                Memory alert sound error

                                1).First removes your Memory card from your motherboard. If your memory card is 2 cards, it so removes all your memory card from your motherboard.

                                2). Clean your Memory card and memory slot with brush.

                                3). Insert all your memory into the slot, and then turn the power on. If you still get the alert sound, it so you must input your memory one by one.

                                4). Sometimes if one of your memories is crush, you can get the alert sound.

                This can be fixed Memory alert sound error.
