The computer won t turn on. Seek help. The computer won t turn on, ask for help.

There is an 80% chance that the CPU is hanging (the possibility of the board hanging at the same time cannot be ruled out).

You can take a look at the motherboard, especially near the CPU slot, if there is no capacitor explosion or resistor burning, it is almost certain that the CPU is hanging.

Try your CPU on another board and you'll find out. But don't try it at the computer repair place, where it can be good or bad.

It should be the CPU burned, you unplug the CPU to see if the CPU slot has burned traces.

Remove the CPU, only connect the fan, don't connect the fan interface wrong, it's on the 4 pins of the CPU, turn it on, it can light up to indicate that the motherboard is good, and the judgment is based on the CPU fan and the power supply fan. You can light it up without a CPU motherboard, but there should be nothing on the monitor.

Why are you so careless!

I can tell you for sure that it was the cup burned

There may be other reasons, such as the memory module is not plugged in properly, etc., which may cause the problem that the boot display does not respond, but through the information you provided, I think these problems can be ruled out

It's possible, in this case, it's best to go to the place you bought and let the boss try the same, and you can't play any tricks if you try again! In my opinion, it is possible that the cup will be scrapped, and it will be mourned

Two possibilities; 1；CPU burn 2;It's that one of the lines inside is not plugged in.

Go directly to the place where you bought the computer to repair, maybe the main version put.

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.

You can use the memory is too small, there should be too many boot startup programs, the memory space of the C disk has become smaller, try to redo the system!

Press the F8 key when powered on to enter safe mode, maybe there will be improvement. If you can get in, then restart the computer and continue to press the F8 key:

At this point, you can choose to use the "Last correct configuration" boot windows] option as a way to resolve issues such as newly added drivers that don't match the hardware.

If you can't even enter safe mode, the only way to do this is to restore and reinstall the operating system!

1.Turn on the computer without pressing the del key, set the BIOS, restore the default settings to save and exit, select load optimized defaults, F10 save and exit.

2.The cause of the problem is that the memory module or graphics card cheat is oxidized or the socket is not in good contact, which causes the computer to fail to boot up. Solution:

You can turn off the power first, open the computer case, dial out the memory module, use the eraser to wipe the part of the gold finger (that is, the place where there is a copper sheet) back and forth a few times, and then insert a memory slot back in, and you're good to go. As.

3.Turn on and press F8 without stopping, enter Advanced, select the last correct configuration, OK.

You try the above three methods. If that doesn't work, reinstall the system.

It's all upstairs, I can only float by, there's nothing to do with me.

Problem Analysis:

If the computer boots up and the monitor has no signal or the screen shows "no sighal", it is generally due to poor contact due to loose or oxidized memory modules, or poor contact with the data cable of the monitor, or damage to the memory, graphics card, monitor or data cable.

Handling suggestions:1If the monitor is powered on but no signal is displayed, turn off (if the short press of the power switch is invalid, press and hold the switch until the power indicator goes out or directly unplug the power cord) Power off the case, replug and unplug the memory module, and wipe the gold finger with an eraser in one direction (the back of the thumb fingernail is also fine), if possible, it can also be installed in different memory slots, and then turned on after installation (before operation, you should also touch the wall with both hands to release your static electricity or wear anti-static gloves). The above may need to be repeated, and if it doesn't work, you need to replace the memory module.

If you have more than two memory modules, you need to test them one by one.

2.If the display can be displayed when connected to another monitor or the display of this machine is connected to another normal host and still cannot be displayed, it means that the monitor is damaged and needs professional repair.

Reinstalling the system, the best solution.

Shut down the computer and reinsert the memory module, and repeat it a few times, but you can only reinstall the system.
