Question about Sony VAIO VGC-RA810G PC Desktop

My computer shut off and won't come back on

When it shut off I tried to get it to come back on but I get nothing. The lights are showing inside the computer. I tried a different plug, different outlet and I get nothing. I had the power supply replaced about 3 weeks ago by someone with the company I had the extended warranty with, which is now expired. I'm not sure what else to try. The computer is 4 1/2 years old,

    it won't turn back on to do anything to it. I get NOTHING....so that's not going to work. I'm wondering if the mother board went out. Would this do this if that's the case?

Most likely your CPU is overheating. Download speedfan from this link. Speedfan monitors the temperature of your CPU. Note the temperature when the PC shuts off on its own. Let me know if this is helpful.

    Sorry I misunderstood your problem. The first culprit is your power supply. Try to swap out your power supply with a know good one and see if the PC boots. Follow the chart on this website http://www.fonerbooks.com/power.htm to troubleshoot your PC.

In my first post I stated I had just had the power supply replaced. The lights do come on inside the computer so it's getting power, it just won't turn on.

Computer won't come on. light is blinking in back of hard drive.


Try unplugging from wall socket then press on button (this clears out extra electricity in PC). Plug back in then try to turn on again. If PC is older, try blowing out the dust inside tower especially around the CPU fan.

Dell inspiron 530 desktop won't boot, fan is running, no signal on monitor


It sounds like either your monitor or video card inside the computer is bad.

If the monitor is showing the "No Input Signal" message then the video card inside the computer is bad. The monitor is ok otherwise it would not be able to display the No Input Signal message.

When you plug in the power cord is there any lights whatsoever on the laptop, where the plug goes in or on the AC Adapter of the power cord?

When you press the power button do you hear fans running, hard drive spinning, lights on the computer, hear any beeps or lights constantly blinking, hear the DvD/CD drive click and the light on the drawer of the DvD/CD turn on for a second or two? If so the computer is trying to boot or may have booted, but the screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with the laptop and why it is not booting. Most times it's a motherboard issue when you hear beeps or blinking lights continuous. Most times the problem is with the memory or Video Card. Count the Blinking Lights or Beeps and take note of their pattern (1 Long or 1 Long followed by 2 Short).

Maybe you have a Static Charge Buildup. Remove the Power Cord, then Press and Hold the power button for 30 seconds. After 30 seconds plug the power cord back in and hit the power button to see if it boots.



Maybe your memory is bad or the memory slot is bad.

Remove the Power Cord, Open the Case and remove one of the memory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x on it with an ink pen. If it fails to boot then move the chip to the next memory slot and try rebooting. If it fails take the chip out and set it aside, then put the other chip in and try booting it in both slots. If it boots, just to verify that the chip set aside is bad, mark an x on it and put it into the open memory chip slot and try booting.

How to repair start-up on my computer


How long is shortly? If it runs and brings up the Windows Desktop and you are allowed to work for 10 minutes or longer then it shuts down, most likely the laptop is overheating. One way to tell if it is overheating is to immediately try to turn it back on after it shuts off. If it will not boot back up, it's overheating. If you let it sit and cool off for a while, then try to boot it back up and it does it successfully, it's overheating.Causes of Overheating:1) Dust all inside the computer. Fans clogged with dust, dust around the vents.2) Fan not working 3) The Thermal Past around the CPU has dried up or is too thin the keep the unit cool.When you plug in the power cord is there any lightswhatsoever on the laptop, where the plug goes in or on the AC Adapter of thepower cord?

Hello, Last night I shut down my Dell E510 desktop - the proper way - by going to the start menu, shut down, turn power off. Then, today, I pressed the power button on the front of my tower and...


This sounds like a definite power issue. This means that the problem could range from being as simple as the power button itself not working/disconnected to the power supply being dead.

Things to try:

1. Have the side of your computer open and press the power button. Notice if any fans start to move or anything that happens.

2. Do you notice the Hard drive light flashing at all when turning on?

3. Has anyone else been using or been close in proximity to the computer that could have bumped it, causing something to come loose?

4. ONLY if you feel competent enough, check the cable connections inside the computer. Make sure to disconnect from the wall for 30 seconds and reconnect before touching any cables inside. Leaving the cable connected allows the computer case itself to act as a ground to prevent static shock.

Good luck!
