Application errors appear on the computer after powering on

Application error occurs after turning on the computer

The system cannot run normally, and a program error is displayed as soon as it is turned on. This may be caused by software or hardware failure. There are many reasons for this situation. It may be system file corruption, virus infection, too many background self-starting programs or too many security software installations causing the system to freeze. It may also be a problem with the memory, hard disk or motherboard. Dealing with this problem requires comprehensive consideration of the above possibilities and appropriate solutions.

Suggestion: Check one by one according to the principle of starting from easy to difficult, software first and then hardware.

1. Restart the computer. If you can enter the system normally, it means that the last abnormality was just an occasional program or system operation error and does not matter.

If you often cannot enter the system normally, you can try pressing the F8 key to enter safe mode or last known correct configuration mode after booting. If you successfully enter, you can exit and restart the system and you should be able to enter normal mode. If you have installed security software, you can use other security software such as 360 Security Guard, 360 Antivirus or Kingsoft Antivirus in safe mode to perform full Trojan and virus scans.

3. If not, press F11 after restarting to see if there is a one-click GHOST, and if so, restore it with one click (one-click backup was required before).

If there is no one-click restore, you can try to use the system U disk to reinstall the system. First, insert the USB flash drive into the computer, and then continuously press the DEL key when turning on the computer (usually F2 or according to the prompt characters on the bottom line of the screen) to enter the CMOS setting interface. Set the USB disk as the first boot item in the BOOT tab. After that, restart the computer and enter the USB boot menu, select clone installation, and follow the on-screen prompts to complete the process of reinstalling the system.

The steps to create a system U disk and reinstall the system are:

It is very simple to make a bootable USB disk. First, buy a 4-8G USB flash drive. Then, search online and download startup USB disk creation tools such as Laomaotao or Dabaicai. Insert the USB flash drive into the computer, run the downloaded software, and follow the instructions to create a bootable USB flash drive. If you have already bought a system USB flash drive that has been made, you can skip the above steps directly.

2). Copy system files: Download the GHO file of operating systems such as WINXP or WIN7 from the System Home website, and copy it to the U disk or the folder specified by the startup tool.

3). Set the USB disk as the first boot disk: Press the DEL key when turning on the computer (usually F2 or other for laptops) to enter the BIOS setting interface, enter the BOOT tab to set the USB disk as the first boot item (Note: Some computers require At this time, insert the USB flash drive for recognition before setting).

4). U disk boot and reinstall the system: Insert the U disk to start the computer, enter the U disk startup interface and follow the prompts to use the downloaded GHO file to clone and install.

5. If you have a system CD (if not, you can go to a computer store to buy it for 5-10 yuan), insert the system CD into the CD-ROM drive, and press the DEL key after turning on the computer (usually F2 for notebooks or follow the prompts on the bottom line of the screen) to enter CMOS, and set the optical drive (CD-ROM or DVD-ROM) as the first boot item in the BOOT tab. Restart and enter the CD boot menu, select to install the system to Area C, and then follow the prompts.

6. If the above operations are ineffective, you need to replace and check the memory, motherboard, hard disk and other hardware one by one to determine the source of the fault.

Application error occurs when starting the computer

This is usually caused by a "conflict" between the downloaded "software" and the computer memory.

Solution:

1) Press F8 immediately after booting, or press F8 until the advanced options appear, then release your hand. Use the up and down keys to select safe mode and press Enter. Enter safe mode and use software to kill Trojans and restore the system. Or reinstall the system (if you can enter safe mode, it means that inappropriate things have been installed. Uninstall all the inappropriate things that were downloaded before the accident. There is also a Trojan. Use software to kill the Trojan. If not, restore the system or Reinstall).

2) If the above method cannot solve the problem, first use software and then hard, reinstall the operating system, do not install software, patches, drivers, etc., and see if there are still problems when booting? If you are not installing drivers, patches, and software step by step, don't install anything that is inappropriate.

Please note: If you install drivers, patches, software and other things after restoring the system or reinstalling, be sure not to install the things that affect the accident, otherwise the restoration or reinstallation will be in vain.

3) In terms of hardware, whether there is any problem with the hard disk, memory, etc., and whether the temperature of the CPU and other hardware is high. If it is caused by hardware problems, it is recommended to check it
