What should I do if the computer cannot be turned on and displays ctrl alt del?

When the computer starts up, it displays PRESS CRTL ALT DEL TO RESTART and cannot enter the system. Based on past experience, it is probably caused by three reasons:

(First, shut down the computer and open the case. , reconnect the data cable of the hard disk and the power cable of the hard disk. This can eliminate the problem that the hard disk cannot be read due to poor contact and the English interface above appears.)

(1) Cause this One of the main reasons for the phenomenon is that there is an error in the master boot record (MBR) of the hard disk, so we must start by rebuilding the master boot record (MBR). The processing method is as follows:

First, prepare a GHOST with PE version of the latest installation CD, whether it is XP or WIN7 (generally you can buy one in software stores or computer stores for RMB 5-8) or prepare a USB boot disk with PE, then turn on the computer and press the F12 key or press the DEL to enter the BIOS, set the first boot item to the optical drive (or U disk), insert the CD (or insert the U disk), enter the CD (or U disk), enter WINPE, and find a software called diskgenius , open this software, find the "hard disk" of the host, select the hard disk, right-click, a drop-down box will pop up, and there will be a "Rebuild Master Boot Record (MBR)" on it, click this "Rebuild Master Boot Record (MBR)" , then a dialog box will pop up, click "Yes", and then a "Task Completed Successfully" dialog box will pop up, click "OK", you can repair the master boot record. Then restart the computer, and the computer will be able to enter the operating system. (As shown below)

(2) Another reason is: the first startup item of the motherboard BIOS is not set properly (usually set to the optical drive and hard disk), which will also cause As a result, the system cannot be booted, and the above English screen appears.

Processing method: Under normal circumstances, this is how it is handled, because motherboards are divided into two categories,

The first category is Award 6.0 type motherboards: This is how it is set: When the computer just starts Finally: Press the "DEL" key or the "Delete" key without letting go (of course, some computers also install ESC, F1, F2, F4, F11, but most computers install DELETE.) until the BIOS setting window appears, and then use Arrow keys, find "Advanced BIOS Features---BOOT Device Priority---1St BOOT Device (1ST FLOPPY DRIVE represents floppy drive SATA: SM-WDC WD5000 represents hard disk CD/DVD: PS-ATAPI IH represents optical drive) Just press here ENTER Select CD/DVD or SATA, and then press F10. The E-text dialog box will appear. Press the "Y" key (can be omitted) and press Enter. The computer will automatically restart, proving that the changed settings have taken effect. Generally, this setting will suffice. Enter the system.

The second type of AMI 8.0 motherboard is set like this: when the computer has just started, press and hold the DEL key (some computers Press F1, F2, F4, F11, ESC (but the most commonly used one is DELETE) until the BIOS setting window appears, and then use the arrow keys to find BOOT----boot settings---boot device priority--enter( OK)--1ST BOOT DEVICE---DVD/CD ROM (SATA: SM-WDC WD5000)--enter(OK)) and then press F10. After selecting the startup method, press F10, and the E-text dialog box will appear. , press the "Y" key (can be omitted) and press Enter. The computer will automatically restart, proving that the changed settings have taken effect. Generally, you can enter the system with this setting.

(3) If you have tried the above two methods and still cannot enter the system, and this screen appears, the only possibility is that the system file is damaged or lost, resulting in the system being unable to boot. In this case, you can only restore it with one click or Use a CD or USB flash drive to reinstall the system.
