Sony desktop will not power on


One of two things usually.
  • Power supply is bad
  • Motherboard is bad


Usually the power supply. They do supply many different voltages so it maybe powering the fans and/or LEDs but the computer wont boot. Very common problem.

Intermittent power on problem in desktop


If a desk top unit and you have to try to turn it on several times to get it going I would suspect bad filter caps in the power supply---once on they will function--usually happens in units at least a few years old.

The power supply if removable can be tested or at least inspected for this as caps will be easy to see if bad----

Power button not working. computer won't turn on. I got a light on, on the mother board but computer won't turn on


This is usually caused by either a faulty power supply or a dirty switch. You can find out if it's the switch by pulling the wires off the motherboard where the power switch plugs in, and with the power supply plugged in, carefully short across the two pins. If the computer doesn't start, that rules out the power switch. The other likely culprit is the power supply. If you can get ahold of a different power supply, try hooking it up and power up the computer. If that daesn't work, chances are that your motherboard is shot. Good luck.

I have a emachines t2984 i press the power button and doesnt turn on i replaced the power supply with different ones and nothing and the light turns on (power button) but the when i press the button the...


Ok, test the power button pins. First disconnect any power source to the computer. Then, find the power pins on your motherboard (the one that your case's power button connects to. Usually two wires, one red and the other black). Grab a jumper a connect it to those two pins, they usually have the letters "pwr" or "power" printed next to them. Then, once you've done this, with the jumper connected, connect the power cord to your power supply. It should turn on by it self. If it does, then the problem is the power button. If it does not do it, then the problem is the motherboard. Good luck.

Hp cpus power supply green light constantly blinking


As always verify all cords are plugged in properly. After that it sounds like you power supply went out. It is not that hard to replace. Make sure you unplug power cord. After you remove the pc cover, Usually you just need to unscrew 4 screws for the power supply. Somewhere on the power supply it should say how much watts it is. Anywhere from 200 watts and up. Just replace with exact wattage.

I just installed a 500W power supply in my Dell dinension 4600i. Now it will not even turn on.The switch on the Antec power supply is on. All connectors are hooked up.


Hi

Does the power supply fan turn? When you first turn it on does the power supply fan twitch? You need to use a power supply tester. This will test the supply under load. What were the symptoms that made you decide to get a bigger supply? Is this a clone supply? I have seen cases of clone supplies not working in OEM equipment. Usually requires a simple wire change.

Computer turning on?


When you say power supply, I assume you mean the power cable plugging the tower into your wall socket. It sounds like your actual power supply inside the tower itself has died. You will have to replace the power supply itself, it is too dangerous to try and repair a power supply, even for an experienced technician. You can find power supplies for pretty cheap online and at PC resellers, and usually a service tech to install for you, if you don't feel comfortable installing yourself.

Before you go this route, make sure you test another outlet as well.
