Computer won’t turn on. Power supply is okay. Is the motherboard bad?

On newer computers, the battery may only be used for the clock. Newer computers actually have UEFI firmware. The BIOS then passes control over to a boot loader located on a device — usually your hard drive, but a boot loader can also boot off a USB device or optical disc. The boot loader then loads your operating system — Windows , Linux , Mac OS X , or whatever else is installed on your computer. The BIOS is responsible for low-level system tasks. You don’t have to remember a key combination, you can just use the Windows 8 boot options menu. We’ll show you how.

Next Prev The wires on the main 20 pin or 24 pin connectors are color coded. These are the same for all ATX power supplies: The green wire is the “power on” sensor. This wire is internally connected to 5V with a pull-up resistor. If you connect this wire to ground any black wire the power supply will turn on. The gray “power good” indicator is at 5V if each of the output wires is operating at the correct voltages.

STEP 1. Turn off the computer, unplug the AC/DC power adapt and remove the battery. Remove screws from the memory and hard drive covers. Remove both covers.

Want a new motherboard? Want to install it yourself? Scared to death of all those cables?

It used to be essential to now reset the machine and hit Delete for the CMOS setup menu, then write down the hard disk heads, cylinders and sectors.

It’s almost certain that you’ll be able to auto-detect the hard drive parameters with the any remotely recent board and drive, though, so this step is now one for the paranoid.

If you don’t see something that looks like that, you may want to get one. Nah, I don’t have one.. I’ll probably have to go downtown and pick one up today. I am reading this, and I hear you say that you do not want to try to start the board by shorting across the 2 power pins. However, you state that you are certain the power supply is not bad, because you have tested each of the power supply leads with a tester.

Your statements lead me to believe that your assessment of your PSU may not be conclusive. A motherboard speaker, so you can listen to beep codes, is a must for troubleshooting these things.

Share Save Every so often, that console-modding Benjamin Heckendorn wanders away from his lair at benheck. If you’re like us, you probably have many fond memories of playing arcade games in your younger days. As the years passed the consoles became the most advanced machines available and arcades faded from the limelight, eventually popping up only as the occasional deer-slaying simulator or th version of Golden Tee. In this How-To we’re going to describe the method by which you can take old arcade motherboards, easily attainable on eBay, and “consolize” them for use with a standard TV and controllers.

Many people are satisfied with emulators such as MAME, and while they’re become better and even more legal thanks to the recent “abandonware” legislation you still can’t beat the real deal. Certain arcade machines, such as the Neo-Geo, are great choices for this project because you can actually plug new games into the hardware using the cheap and plentiful “MVS Cartridges.

The power supply unit inside of an ASUS computer is responsible for providing power to all of the components inside of the PC.

It converts a couple of 4 pin peripheral power cables into an 8 pin 12 volt cable. If you use one of these adapters then be sure to plug the 4 pin peripheral connectors into separate cables coming from the power supply. If you plug them both into the same power supply cable then you are drawing all the power of the 8 pin 12 volt connector through a single 18 gauge wire. You can often get away with that but there’s no reason to do it. If you leave the two pieces separate then you can plug one of the 4 pin pieces into a 4 pin 12 volt connector and leave the other 4 pin piece unplugged.

If you look carefully at the image above then you can see the polarization of the pins which prevents you from plugging the cable in improperly. Some of the pins are square and some of them have rounded off corners. The motherboard connectors have matching square and rounded off corners to prevent the cable from being plugged in the wrong way.

But if you look really carefully at the right half of this particular cable and then look at the 8 pin 12 volt cable pictured above you’ll notice that they don’t match.
