Check the power switch on the power supply - should be located close to the power cord entry. Place in the '1' position for ON. The '0' position is OFF.

My Gateway DX 4300-05 won't start. Not even the power supply. Does the motherboard have a reset?

If I am reading the frist part of your stament correctly, the power supply does not even kick on when you press the power button. Don not unplug anything from the inside of the computer at this time, instead check your power cord and make sure it is plugged in thightly to both the computer and power strip. Check to make sure the power strip is on, plug something else (like a light) and test the power strip. If the item does not come on, then you may have a bad power strip. To confirm plug the item you are testing with into the outlet the power strip is plugged in to and see if it works. If not your outlet may be bad, contact an electrician. If everything works, but the power supply is still not kicking on, you possibly have a bad power supply. You will need to pick up a replacement power supply and install it in the computer. This is were you unplug everything wire bundle that comes from the power supply to the mother board (paying attention to what was plugged in where). Take the new power supply, install it, plug everything back in. Now try the power button. If this fails then yes you have a bad mother board.

I know most computer retailers that offer repairs, have a device to check the power supply. A good repair place will check this at little or no cost to you, if you agree to let them install the replacement if it is bad (they will charge you for the power supply and installation of it).

I hope this helps

Tower turns on but nothing appears on monitor

You need to follow the easy steps and get rid of it

1. Make sure your display (moniter, CRT, LCD, screen, whatever you prefer to call it) is plugged into a wall outlet or power strip and powered on. Also ensure that it is securely plugged into the back or bottom of your display. Many displays do not have removable power cords, making them more prone to shorts and other damage. Check your cable to make sure it isn't damaged.
2. Make sure the power strip or wall outlet that your display is plugged into are functioning by plugging another electrical device, such as a lamp, into it and switching it on.
3. Check the connection between your computer and your display. Make sure that it is completely plugged into both as well as fastened with the attached screws.
5. To double-check any possible cable problems, if at all possible, swap out the screen's power cord and the cable connecting your computer to your display.
6. Swapping out your display is also a good way of narrowing down the problem. If you get the same result with a different display, then you can be near positive the problem is something in your computer. If switching displays fixes it, then the culprit is a faulty display.
7. Try turning your display on and off. Does the power indicator light change? Green means On, amber means Standby, and no light means no power. If your display starts out green when it is turned on, then goes to amber, that usually means that it is not receiving any signal from your computer and therefore assumes it is not needed. The problem is most likely not with the monitor but in the computer.

No power to pc

You possibly have a bad AC cord, AC input port on the computer, or a bad circuitry.

The first step is to try the cord in a different outlet. If unsuccessful, change the cord to a new cord.

If unsuccessful, make sure that the ac input port on the computer is secure and not able to be moved when plugging in the power cord.

The next step after that would be to open up the computer to check circuitry and wiring. I would highly recommend that if you are not a professional to take it to a computer repair shop to diagnose and fix.

I hope this was helpful.

My computer does not start up

hi im josh in cebu phils.may i help you? Friend try to use these solutions i got this in my book.
Dealing with System Startup Problems There's nothing scarier than turning on your computer and finding it doesn't start. What you do next depends on exactly what it is your computer is or is not doing. Let's work through some specific startup problems, and how to proceed in each instance.
Problem: Your Computer Doesn't Start—You Hear No Noises and See No Lights First things first—don't panic!
Now, very calmly, look at the back of your system unit. Is the power cable plugged in to the right connector? Now follow the power cord to the other end. Is it firmly connected to a power outlet? Now check the wall switch. Is it turned on? Now walk to your fuse or circuit-breaker box. Is the fuse good or the circuit breaker set? Now go back to your computer. If it still isn't working, unplug the computer from the power outlet and plug in something that you know works—a lamp or a radio, perhaps. If the appliance doesn't work, you have a bad power outlet. If the appliance does work, you really do have computer problems.
If you're positive that your computer is getting power and that you're turning it on correctly, you probably have a hardware problem. The most likely suspect is the power supply in the system unit. To determine the culprit and fix the problem, however, you'll need to call in professional help at this point. Take your system to a certified repair center and let its technicians get to work.
Problem: Your Computer Doesn't Start, but It Makes the Normal Startup Noises If your system is making noise, at least you know that it's getting power. Because you can rule out a bad power cord, the most common things to look for are poorly connected cables or a nonfunctioning monitor.
Begin by checking your monitor. Is it turned on? Is it plugged into a power outlet? Is the power outlet turned on? Is the monitor connected to the correct port on your system unit? Is the connection solid? Is the connection solid in the back of the monitor? Are the brightness and contrast controls turned up so that you can actually see a picture? If you have a newer monitor, try disconnecting the monitor from the computer (with the monitor turned on); if the monitor is working correctly, you should get a No Signal or Lost Signal message on the screen.
If everything is connected and adjusted properly, you might have a monitor that needs repair. Is the monitor's power light on? If not, your monitor might have power supply problems that need attention from a professional. If your monitor's little green light is on but nothing shows onscreen, the video card in your system unit might be loose or set up incorrectly. Try swapping monitors with another system; if the new monitor works on your system, your monitor is the problem. If you determine that your monitor is working fine, you should check your video card to make sure it's installed, seated, and connected properly. If that doesn't fix your problem, try plugging your video card into a different slot.
It's also possible that your keyboard isn't plugged in properly, or that you have some other internal problem that causes your system to halt during start-up. Check all your connections before you try rebooting. good luck hope i helped you.

Power failure

by plugging it directly into the wall... what was it plugged into before. and have you actually taken some other electrical device and plugged it in to make sure the wall socket is still live.
there is also a reset button on most power strips... it may have tripped.

Try those and let us know.

How old is your computer? Did you recently have a power outage or anything? Most the time if a computer won't turn on, something in it went bad OR an outlet is bad. Try this:

1. Make sure that the power switch is on, the switch in the back (on the power supply itself) is turned on, and everything along those lines is functioning.
2. If that doesn't work, and it will not power on AT ALL, make sure the cords are plugged firmly in place, including the surge protector and/or the power cord itself.
3. Try resetting the surge suppressor and/or plug the computer into a different outlet in the surge suppressor. Try other items in that surge suppressor (or even in the wall outlet, if that's what you're plugged into) to make sure that the outlet itself is working.
4. If your computer is plugged directly into a working wall or surge suppressor outlet, try a different power cord.
5. If your surge suppressor works, your wall outlet has power to it, and you are using a known-good power cord in the computer, you will have to go into more in-depth investigation as something inside the computer likely went bad. It could be the video card, motherboard, CPU fan, power button, or the power supply itself. Start by testing the video card and the power supply by (one at a time) swapping out a known-good component for the one you suspect may be bad. If it won't turn on after that, try swapping out the next and try it again. If it still will not work, it could be something more serious such as the motherboard or power button.

Good luck!

it could be a bad power supply or a bad motherboard. Other problems might cause issues, such as a bad video card.
