Excuse me, my computer doesn t turn on somehow

This situation requires a step-by-step approach to diagnosing the problem. The first thing you have to do is:

1: Check whether the power socket is plugged in tightly.

It's best to try a different power cord first.

2: If it is not a problem with the power cord.

Then check if the fan of the power supply is turning when you turn it on.

If there is a rotation, the power supply is working.

That's probably an internal issue with the host.

3: Check whether there is a system alarm sound when the machine is turned on.

If so, you can find the relevant [host alarm prompt].

Not much to say here.

If there is an alarm. Let's not talk about how many lengths and how many paragraphs.

The first thing to do is to open the chassis. Unplug the memory. and graphics card plus network card.

Clean up the dust. Then use a brush like a leather to brush the graphics card, memory, network card, (interface)...

It's best to clean up even the dust in the host.

Dust accumulation can easily cause short circuits.

Then plug the graphics card memory network card back in.

Turn it on to see if there is any problem.

If the problem persists.

Then you can unplug one of the memories [it may be a broken memory] if it still doesn't work. I suggest you take it to the computer city and see what the problem is.

Is the power supply fan turning? If you don't turn around, try changing the power supply.

If the problem is something else, it must be analyzed on a case-by-case basis.

You write specifically, and everyone will help you analyze.

If you can't turn on the computer, you can't even turn on the host, or you can't enter the system?

In fact, there are many reasons why it can't be turned on, such as no power and memory sticks, which need to be checked one by one, if there are no problems, you need to take it to the repair shop to check.

Just follow the prompts above to enter the advanced option to select the repaired computer.

If you can't boot up, use the USB flash drive boot disk, select the USB flash drive boot disk in the BIOS settings to boot the computer.

Then reinstall the system.

If the system problem cannot be repaired automatically, the system can only be reinstalled.

Reboot press F8 to select the last correct boot configuration.

Or repair it with a system image.

or reinstall the system.

That's fine, it's a problem with the memory module.

1. The system file is corrupted and the system needs to be reinstalled. Solution: Make a PEU disk and reinstall the system.

2. The system boot is damaged and needs to be repaired. Solution: Make a PEU disk, there is Windows boot repair on the PE system desktop, open the repair boot.

The system file is corrupted and can only be resolved by reinstalling the system.

Your computer's Windows system is broken and you need an installation disk.

Hello,Hehe,I've also encountered this situation.,Pull out the memory card and erase it with an eraser.,Or it's the graphics card.,But most of it is because of the memory.,Because the computer will heat up the motherboard after a long time.,After shutting down, due to thermal expansion and cold contraction,It's easy to make the hardware change hehe,Okay,It's very tiring to play so much.,The landlord supports it.。

Is the computer not powered on or the system crashes into what system what computer can you elaborate.
