Computer Still Shuts down

I posted this before but although I appreciated the replies, I think overheating or bad software is not the reason my Vaio shuts down. For one, if it were an overheating issue, I would have to wait until the computer cooled down a bit before I could use it again but all I have to do is disconnect and reconnect the power cord. In fact, last night it was off all night and when I tried to fire it up this morning, it wouldn't start until I (you guessed it) disconnected the power cord and reconnected it again.

I'm stymied. I never heard of a problem like this before. How can the simple act of disconnectig and reconnecdting the power cord (or, BTW sometimes just the extension cord from the wall socket) solve the problem only to have it repeat a few hours later?

Any thoughts?

Re: Computer Still Shuts down

I had the same problem with mine. The fan on the back for the power unit gets clogged with dirt. Take the lower back cover off the unit and clean the fan in-take. Problem solved.

Try running a check Disc on the system drive go to start programs run and type in cmd once there type (chkdsk C:/x) exactly like that with the X say yes to the prompt that ask you if you want to dismount the volume, if it asks you if you want to run it the next time the system reboots say yes and reboot. It should start running before the computer logs on. Kick back and relax it takes between 2 and 3 hours to finish. If this doesn't work it might be a hardware issue.

Hp pavillion slimline shuts down for no reason

Although you think there is no reason, the computer has a different opinion.
Most of the time when a computer (most electronic devices) shuts down, there is something wrong. Most likely the computer is running hot for some reason. Not knowing how long it will stay on, there is little advice. If it is running for minutes, you could try to install a monitor program for the hardware. And let the program tell you how hot the processor and the mother board are.
But perhaps cleaning all dust out of the fan's and power supply so air can flow through, will doe the trick?

Following are the reasons for overheating, just take care of these things::

Computer Randomly Shuts off

If it only seems to be shutting down when connected to a 2nd screen, it's your GFX card that's overheating.

Normally, you'd hear a beep or two before it dies, but that would only be if you have the pc speaker connected to your motherboard, and also only if the card manages to send the error to the motherboard before it shuts down.

I'd suggest trying to cool down the inside of your case a bit more - add an extra fan or two to get the warm air out. If the card you have is nVidia there is a gadget that tells you the temperature of your card - you can find it on Microsoft's Win 7 gadgets page. I'm not sure if there's a similar gadget for Radeons.

If the card is overheating, that gadget will show the operating temp, and give you an idea of what you may need to do (and it's free)

Hi to all i had an old dell gx270 and last week i pulled it all apart the motherboard the drives everything and i dont know why today i decided to fix it back and i did it well but when i turned it on...

It's overheating. Check the heatsink and fan. Make sure that it's not loose. Make sure the fan is plugged into the motherboard.

Make sure to put back that green shroud.

It sounds like it could be a problem with overheating, which is causing the machine to turn itself off. Try opening the side cover, and carefully cleaning the motherboard and especially the CPU fan - which is the large fan probably on top of a silver box with loads of fins on it. Carefully remove the dust, and see if this clears up the problem. It may be worth removing and refitting the memory whilst the computer is open, to reduce the problems of bad connections between the cards.

If it doesn't fix it, then reply here with any error messages that pop up on the screen.

The PSU has a thermal heat related problem, try replacing the PSU with a new one, they are quite cheap. I think this will sort ya problem.
Are you sure the clicking isn't comming from the hard Drive? & they are both on way out as bad PSU can "Hurt" other bits.

Sony Vaio desktop will not load windows

what your describing is a hard disk failure the computer cant or wont read the hard disk to boot the machine, so it shuts down. Sounds like the hard disk died from a bad virus. and the computer wont run. Best I can do for you is either format the Hard disk and reinstall the operating system or buy a new hard disk. Cheers

My computer shut off and won't come back on

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.
