My computer keeps shutting down by itself. Help!!! Please.

1. What keep says basically is: "Limited Connectivity".
2. The Ethernet Controller has a yellow question mark on it, when you see it in the "Device Manager".

That means there is a problem with the device.
Try Reinstalling the driver should fix it.

You can do this by going to the Manufacturer's website, look for the right driver and installing it.

I have to go now, it's kind of late here. If there is anything else, I'm sure someone will be glad to help. (of course i'll be back)

Thank you, thank you, thank you.... so much for your help and your patience.
It sure means a lot to me.

My computer also kept shutting down by itself. Diagnosis: the battery was dead. Even if i had plugged on the computer to the wall outlet, it turned out that my power cord was defective -- it was not transmitting any electric power to the computer. So the computer just relied on the battery-- which gradually got depleted. A new power cord with new Power Module fixed the problem.

Nothing wrong with the fan. No problem with overheating.

How is the cooling?

If you download Speed Fan, can you please tell us the temperature(s) it lists.

Has his always happened?
Does it happen when you do something specific (like play a game) or does it happen in general?

I agree with him. I will use this on my overheating PC too.
