Let's start with some of the basics.

1) Since you were checking connections on the motherboard, was the power unplugged from the computer, AND did you follow Anti-Static precautions?

[Anti-Static Precautions:

Your body carries Static electricity.
Static WILL fry out (Short Circuit), the hardware components inside a computer.

You may not even see it, or feel it.

Computer unplugged from power, computer case open, computer on a table.
TOUCH the metal frame of the open computer case to relieve your body of Static.

Should you get up in the middle of working on your computer, and leave, upon your return Touch the metal frame again.
Or use an ESD wrist strap, and connect the alligator clip to the metal frame ]

2) Computer unplugged from power, anti-static precautions followed, remove all ram memory modules, and reinsert them. In fact, it would behoove you to clean the contact pins on the bottom of the ram memory modules, before reinserting them.

Clean with a pencil eraser. Remove the eraser dust, with air pressure from a can of compressed air for computers, or air pressure from your mouth may be sufficient.

You may have bumped the ram memory modules.
Even if they look to be seated, it only takes a few minutes to remove, and reinstall.

After time, corrosion can develop on the gold plated contact pins, at the bottom of the ram memory modules. Doesn't take long to clean them with a pencil eraser.

Handle the ram memory module by the body. The body, is coated with a clear see-through protective plastic.

http://en.wikipedia.org/wiki/File:Generic_DDR_Memory_%28Xytram%29.jpg

The above link, is only provided for an illustration of the gold plated contact pins, I am referring to.

It is DDR Sdram ram memory, and has 184 contact pins. 92 on each side.

Your computer uses DDR3 Sdram ram memory.
Has 240 contact pins. 120 on each side, and the Locating Notch is in a different place.

3) Are you sure the 4-pin ATX +12 Volt power cable, is plugged in tightly to the motherboard?

This is power for your Processor.

SATA power cable is plugged in tightly to your SATA harddrive?

http://www.playtool.com/pages/psuconnectors/connectors.html#sata

If your SATA harddrive has provisions for plugging in a SATA power cable, and a 4-pin Peripheral power cable, BE SURE that only the SATA power cable is plugged in.

Plugging both in will fry out the harddrive. Maybe not right away, but will down the road.

Gateway dx 4300-11 will not shut down, have to unplug


There is a setting for the power button . If you go to your control panel & click on power options , then click on advanced . There you will see where it say's " When I press the power button on my computer , I want it to " you can pick the option that you want it to do ( shut it off, sleep mode , ect ) That should do it . If it does not help , then it's the power button itself.or the connection to the power button . Hope this helps .

I have a Gateway computer running Win98 that prompts me for a password at startup. It didn't use to do this, so I don't know what password it is asking for. Never used one! It is doing this after a power...


Somehow, the motherboard thinks that a "start-up" password is required.

If you have a desktop computer, turn the computer off, open the case, and look on the motherboard. Look for three pins (labelled 1, 2, and 3), and look for a small "jumper" that is connecting pin 1 to pin 2. Move the jumper to connect pin 2 to pin 3. Wait 5 seconds.
Move the jumper back to connect pin 1 to pin 2.
Turn the computer on -- the "BIOS-password" will have been removed.

Power supplies shut off automatically when one of the voltage wires is shorted to ground somewhere. This is why you see the fan kick over for a second and quit. This is probably a bad motherboard.

Asus a8v-vm se fans always run


Hi jderek4, try this. locate the toggle switch on the back of the power supply. Just find it do not flip it.
Plug the PSU's power cord into the PC. Just as you got a good connection & the PC begains to power up move the toggle switch to it's other position. The PC should power off that very second.
If the PC does not shut off than the PSU is bad. If it did shut down wait a few seconds. Press the cases power on button. The PC should start to boot up. Let it finish loading. Click the start button & choose to shut down windows. The PC should shut off.
Yes? If not than your back to (bad power supply). Swap it out.
