Shut down

Excess heat will cause many problems. You can check to make sure the cooling fans are running. One is in the Power supply which you should be able to see without taking the cover off. One will be on the CPU itself. You will need to remove the cover on the computer case to see this. Turn off the computer, take the cover off, turn the computer back on and take a look at the CPU fan. If they are not running or are running slowly or sporatically, they would need to be replaced. Do not leave the cover off for long periods of time as it is part of the cooling system.

Also while you are in there, it is a good idea to clean out the dust that has accumulated. Make sure you are careful not to induce any static electricity in doing this. I usually use a can of compressed air and carefully blow out the dust. If a vacuum is used make sure you can ground the wand so it does not build up static electricity.

If there are actually components "leaking", you need to take the computer to a fix'em-up-shop. If it is old, you may want to consider that it may be time for a new computer.

Definitely need to get the leaky caps

replaced. They filter the DC power to the CPU. Without adequate filtering the CPU will perform in a very flaky manner

If the mobo is an ABIT, they lost a class action suit and are ordered to replace and rewarrant any mobos with defective capacitors.

For any other mfr's mobo, I would also complain loudly to the Mobo mfr. They may agree to repair or replace. Most mobos are warranteed for 3 years by the nmobo mfr.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
