Default Computer keeps crashing......(Shutting off)

Hello All. I'm new here....

My computer keeps powering down without any help from me.
It might run about 10-15 minutes then it sounds like a fan comes on and within 5 minutes down it goes and I cannot power it back up completely for 30 minutes or more.
Any idea what the problem might be and how to fix it?

I'm guessing that it's over heating.

thanks,

Gary

You are correct. It does sound like your laptops fans are clogged with dust. Apart from stripping the laptop down to get to the fan you could get a can of compressed air and try and blow out as much dust as possible.

Alternatively some laptops have a hatch on the bottom of the laptop that can be opened to easily gain access to the cooling system so it can be cleaned. Check for a plastic hatch that can be unscrewed near the laptops heat extraction vents.

Of the laptop feels hot to touch when it shuts down then I'm pretty sure this is your problem. If so then I would get it seen to ASAP as it can damage your processor or worst case scenario your motherboard.

You could also try installing a free program called speed fan. This program can tell you the temperature of your hardware. Report back the results here and we can see if the temps are correct. Just google speed fan.

This is a desktop computer.
I would assume the same would apply to a desktop as a laptop??

Ah ok. sorry for the bad advice then

In this case it could be the PSU (power supply unit), Ram, or overheating.

When the computer crashes bad enough sometimes its set to just turn off instead of displaying an error message. This is good if its a one time thing however if it keeps happening then you will want to use the information to diagnose the issue.

Try turning off the automatic shut-down on system failure by following these steps listed here Automatic Restart XP - How to Disable the Automatic Restart on System Failure in Windows XP for XP and here Automatic Restart Windows 7 - How To Disable the Automatic Restart on System Failure in Windows 7 for vista and 7.

If you dont feel comfortable opening the case of the pc it may be worth downloading speed fan and seeing what temperatures the computer is giving. Post the results back here.

Also you could download a copy of memtest (google it) and burn it to disk from another pc if possible, then just insert it into the pc that keeps turning off and let it run and post back the results.


However if you want to open the case then read on.

In your case it can be the same problem. But as its a desktop it will be easier to fix. If its a standard size computer then all you need to do is either unscrew the two screws at the back of the desktop for the left panel (when looking from the front) after this slide the left panel back and it should come off.

If its a dell then you may have a tab at the top that you need to pull back and the side will pop out from the top and then you can just lift the cover off.

After you have access im sure there will be a fair amount of dust. Get a hoover and on a fairly low suction give the computer a clean out being carefull not to be too harsh on the components.

You will see a big fan and metal heat sink, this is the part that cools the Processor and if this gets too hot then it can cut the computer out (as your experiencing). Make sure that the metal heatsink does not have dust trapped between the metal and the fan. If so try and get the hoover and clean the dust away.

Alternatively if the dust is not too bad it may be the PSU (power supply unit) that may be going bad. If this is the case you will need to get yourself a new one

First things first, try giving the internals a clean out and see how you go.

Sorry about the random comment I meant to say, but I had just found it amusing that a fan had dropped off, I was tired :\
