What happens if the computer doesn t turn on?

Turning on and unplugging the keyboard may damage the motherboard.

You'd better take a repair shop and get it tested.

I don't think the problem is that serious, you unplug all the cables of the case, short the power jumper of the motherboard, see if it can boot, or discharge the BIOS and try again.

You may have messed up the motherboard. The keyboard and mouse of the PS2 interface can't be pulled out with a point.,10 times with a point of pulling out may burn the motherboard 1 time.,Unfortunately, you hit it.,And it's a double pull.,Go to the repair shop to repair the motherboard.。

PS2's mouse and keyboard do not support hot swapping, which may burn the motherboard, so you unplug everything first, leaving only the power motherboard, and see if the memory can still alarm.

It seems that the landlord is a layman.

Now let me tell you, do not plug and unplug any device in the boot state, that will cause serious damage to the motherboard, and in serious cases, the motherboard will be burned.

Now that's your case, change the motherboard.

CPU contact is not good. I feel.

Check if the power connector is connected, and try again, if not, you are having a problem with your motherboard.

The motherboard is damaged, the power supply should be reflected, mine is that the power supply fan is not moving, the power supply should be broken.

Since the shock of your live plug and unplug current burns out the power supply, it is OK to replace the power supply.

Failure to shut down the computer in accordance with the prescribed procedures naturally caused some malfunctions.

I've seen this happen, it's the power supply that's broken.
