The computer could not be turned on, and the ticking sound of the loudspeaker was intermittent, and

Hardware issues. It is possible that the individual hardware is not in good contact. It is recommended to send the machine to the shop to clean the ash and reinstall it.

Hehe, lz is a very simple question. Generally, after the computer has been used for a long time, there will be such a problem. I'll take care of it for you.

The steps are as follows: 1 Take the fan: Open the case of the computer, remove the fan, remember to be careful, the fan will generally be closely connected to the motherboard, be careful not to touch the surrounding capacitors when screwing, and some fans will also install some spring cards to assist in fixing, this thing should also be careful when taking it off.

For the above process, you can also refer to the motherboard installation manual, which will also have corresponding instructions.

2 Clean up the dust: If you don't have a tool like a leather tiger, you can take the machine outside and clean it with a dry toothbrush, of course, this method can clean all the dust on the fan and motherboard.

There may be some dirt on the fan that can't be wiped off with a toothbrush, you can use a damp rag to clean it up, but remember to be sure to install it after it has dried.

3 Oiling: After cleaning the dust from the fan, you can choose the oil to improve the lubrication of the fan's drive shaft, preferably the sewing machine oil! Open the small sticker with the logo on the fan, and do not open half of it to the main shaft, so that it is easy to re-affix it.

Be careful not to let the oil drip onto the label, otherwise the thing won't be able to go back. It does not have the effect of preventing the volatilization of engine oil.
