The computer is turned on, there is no prompt sound, and the monitor does not display, what s going

This is usually a problem with the CPU or motherboard.

For example, the CPU is not working, the motherboard is not powered, or only the power supply part is overpowered.

If you understand something.

So, take the CPU fan off, blow the CPU, take it out and reinstall it, take out the memory, erase the gold finger with an eraser, and then install it.

And then what about hair dryers blowing dust from the chassis.

If it doesn't work, send it for repair, so if it's not a contact problem, it's hardware damage.

This is something that I often come up with ---

My method: put all the wiring and memory inside the computer. Hard disk.

Optical area line. The power supply is all unplugged. Plug it in again - cpu remove.

Replace. - If it doesn't work. Please repeat this several times.

I've been in this situation 3 times before. All use this method. It's all right.

The last time I encountered this. None of those methods worked.

I'm very angry. I think the host is almost scrapped.。。 I kicked about 4 feet on the host as I played.。。 Miraculously good. It's magical.

Let's be professional: if none of the previous ones are enough. Look at the capacitors on the motherboard yourself - look at each one carefully.

See if there are any bulges. Or burst out. As long as the capacitor is slightly deformed and raised.

Then that's your problem. Pull it directly to the professional repair. Just change the capacitor...

Complete. **Divide.

Since it should be a problem with the motherboard or memory, unplug the memory and reinsert it, and then buckle the battery on the motherboard and discharge it!
