The computer screen does not move, and neither the keyboard nor mouse works 15

Since this kind of problem occurs due to high temperatures, it seems that it may be a problem with heat dissipation, CPU or graphics card. Try to improve the heat dissipation environment of the case, for example, put it in a slightly colder place, the cooling fan behind the case should not be too close to the wall to affect the exhaust air, or add one or two more fans can also be considered, the fan is not expensive, it may only look like 10 pieces.

If it's a little too much, you can consider pulling out the CPU and reapplying some silicone grease. Be careful not to break the CPU when operating.

Try reloading, if it's still not good. It's still a matter of heat dissipation, apply some silicone grease and change a good fan.

It may be a system problem, you try to reinstall the system.

I don't know if the landlord has changed the power supply, change the high-power power supply to see.

The computer screen does not move, the mouse and keyboard are used and this does not work:

1. Loose memory modules, bad contact, and dust accumulation will cause the screen not to be displayed. Solution: Unplug the power supply, remove the memory module, remove the floating dust at the interface with an eraser, and wipe it clean with letter paper.

Put the memory module in alignment, put the index finger of both hands against both ends of the card holder, press the memory module with your thumb, press down, and hear the "click" sound, it's OK.

2. Motherboard problems. Solution: Unplug the power supply, remove the motherboard battery, and jump the CMOS jumper to"colse"Position, hold for more than five minutes, install the battery, and resume the jump call with the cable.

That's it. Or use a paper clip to turn on the positive and negative electrodes of the CMOS on the motherboard for more than five minutes, and it will be OK

3. There is a problem with the power supply. Hidden space solution: Unplug the power connector of the motherboard, use a paper clip to connect the "green" and "black" wires, if the power supply fan does not rotate, it proves that there is a problem and needs to be replaced.
