No Power When Pressing the On Button

power-buttonAn example would be you try to turn your computer on, but nothing happens. You verify the power cable is connected and other devices connected to your power strip are working, yet your computer will still not turn on. This is usually do in-part to a bad power supply.

A replacement power supply typically costs anywhere from $40 to $100 depending upon how many watts your computer requires. There are a number of things to check before buying a new power supply. The first and most important thing to check is the number of SATA and IDE power connectors that your current power supply utilizes. There are other factors such as +12V rails that help provide power to high-end video graphics cards.

It always best practice to remove your current power supply before you begin shopping around.  If your computer is more than 5 years old, it may have a 20 pin connection instead of the standard 24 pin used today. Shop around the Internet at places like newegg and amazon before making your purchase at a large retail store. If you’re willing to wait a few days, I’d recommend buying online. You’ll be able to read reviews about the product and save a fair amount of money.

Nothing Appears On The Screen

Another very common issue is powering your computer on yet nothing appears on the screen. You’ll see the power button light up, and you’ll hear the fans kick in but nothing else happens. This one is pretty easy for do-it-yourselfer to fix. The first thing you’ll need to do is completely disconnect all cables running to your computer. Disconnect the power cable, the mouse, keyboard, printer and any other USB device plugged in.

Take the case side-panel off to gain access to the internal computer components.

Computer Case

The first thing you’ll want to do is re-seat the memory (RAM). Just take it out, then put it right back in. This normally fixes the issue over half the time. If that doesn’t work, move on to re-seating the video card. A lot of the computers sold these days have the video card built into the motherboard. Either way, if you find the video card was not the issue or the video card is a part of the motherboard, move on to the next step.

The BIOS (Basic Input/ Output System) is a small chip attached to the motherboard. It contains the first piece of code to run when you power on your PC. It contains a list of all hardware attached to your computer and what the settings are for that hardware. Sometimes those settings become corrupt. In order to reset the BIOS, simply remove the BIOS battery.

You’ll see the battery attached to the motherboard. It looks like a large watch battery. Simply pop it out for about 3 minutes then put it back in. If successful, you should now have a working PC. The only downside to taking the battery out is all of your settings will be erased. You will be notified on the first boot the date/time and other settings need to be adjusted.

If after performing all of the steps you still do not see anything on the screen, there’s an almost 100% chance you have a dead motherboard on your hands. Because the video card is attached to the motherboard, there is no way to remove it. You will be forced to replace the motherboard or purchase a new computer. Replacing a motherboard is probably one of the more complex computer repair tasks to try and accomplish on your own. Use this site to find a local computer repair technician.
