When the computer is turned on, there is an English letter string, and you need to press the enter k

It should be a blue screen.

1: Sudden power failure.

2: The broken screen of the software is uninstalled.

It is recommended to reinstall the system.

It's not very clear.,I guess it's the system that chooses the time, right?

You try right-clicking on my computer ->-Properties->"Advanced"Tab - > Startup & Failback"Settings"Just remove all the ticks.

Because your BIOS is not properly set, if you don't have a floppy drive and disable this in the BIOS, it's fine.

Reason: This is the system scanning your hard drive, it may be a problem with your own operation, if you shut down illegally, directly power off or directly press the power to turn off, the computer will check your hardware when it is turned on, including your hard drive.

There is a real hard disk problem with your computer, it is recommended that you use the disk scanning tool that comes with the computer to scan and repair, if it is more serious, use the following software to repair.

Solution: 1. Press the delete key to enter the BIOS interface when booting up, change the first boot item to CD-ROM drive or USB disk boot in the device boot sequence management item, and then save and exit.

2. Put the disc into the optical drive or insert the boot USB disk into the computer and boot it, select the PE system when you boot into the options, and then you can partition and format the hard disk after entering the PE system, and then copy the system installation file to the partition of the computer for later use.

3. Start Ghost on the desktop of the PE system, and then mirror the system files to the system disk (C disk) and exit Ghost after the image is completed, and then restart the computer for system installation, and restart the computer when the system installation is completed.

4. After the system installation is completed, you can go to the official website of the computer driver to install, including the motherboard, sound card, graphics card, network card, etc.

The English letters that appear when the computer is turned on may be after the self-test and self-test are completed. In this case, if you can enter the system normally, there should be no big problem.

There is no problem with this, this is some information that will be displayed during the computer self-test process, as long as it can be turned on and used normally, there is no problem.

The English letters that appear on the computer are called self-test.

When the power is turned on, the computer first automatically runs the BIOS program solidified inside the ROM chip on the motherboard, often referred to as the Power on Self Test (POST).

The complete POST self-test includes testing of the processor, system motherboard, basic 640KB memory, more than 1MB of extended memory, and system ROM BIOS; Validation of system configuration in CMOS; Initialize the controller, test the memory, check the signal and the synchronization signal, and test the VGA interface; Check keyboards, floppy drives, hard disks and CDROM subsystems; Check the parallel port (printer) and serial port (RS232).

If there is an error found in the self-test, it will be handled according to two situations: for serious faults (fatal faults), the machine will be stopped, and no prompts or signals can be given because various initialization operations have not been completed; For non-serious faults, a prompt or audible alarm signal will be given, waiting for the user to deal with it.

I hope I can help you with your doubts.

The English alphabet appears when the computer is turned on, and it will turn on normally after a while, which is a normal phenomenon, and this cannot be solved.

It's really not possible to reinstall the system, if you can't reinstall it yourself, go to the maintenance there to find a maintenance person to help you, it should take a little to spend it, if you can't turn on the machine by any method, this is a sudden shutdown, caused by disk damage, one is to deduct the motherboard battery and put it down, one is to put it for a period of time in the boot to try, or you can't repair it.

I'm having the same issue.

It can't be that you changed the power adapter, right? How could it not be matched?

If it has not been replaced, it is a problem with the adapter that causes power supply problems, and it is best to contact Dell to avoid unnecessary losses.

Your power isn't plugged in properly or you're on battery mode!

He advises you to plug it in for the best results. It doesn't matter.

First go to the BIOS and find the Load Default BIOS....Are you sure.

The tip is a problem with the power adapter.

You can go into the BIOS to restore the default settings.
