Boot requires pressing F1 to enter the system troubleshooting.
Under normal circumstances, the requirement to press F1 to enter the system is caused by a minor problem with the system's BIOS settings that do not affect the system startup, so please check the hardware information settings in the BIOS for discrepancies with the actual situation.
The common faults in general are:
1. The battery on the motherboard is dead.
Solution: Replace the motherboard battery.
2. You have set up the floppy drive to start, but there is a problem with your floppy drive.
Solution: A. Press del to enter the BIOS at boot, boot up the boot sequence, and turn off the floppy drive to boot.
b. Turn off the detection function of the floppy drive when it is turned on
Start the computer and press the [DEL] button to enter the main BIOS settings interface.
Select the "Advanced BIOS Features" setting item and press the Enter key to enter;
Set "Boot Up Floppy Seek" to "disabled" to turn off boot software detection.
-
First enter the BOIS, reset each setting, that is, according to the settings of the computer self-test, do not change, press enter directly for each parameter, the most important thing is the CPU settings, to see if it is consistent with your CPU parameters.
Finally, save the settings.
If not, let's talk about it.

When the CPU fan is turned on, the CPU fan is error, and you need to press F1 to enter, which is due to the following reasons:
1. The CPU fan is plugged in the wrong place, resulting in the BIOS not detecting the CPU fan, so an error will be reported; Just replace the CPU fan header.
2. The motherboard wiring detects that the fan does not match; Just turn off the CPU fan detection in the BIOS, go to the BIOS, select Power, then select Hardwear Monitor, find the CPU Fan and reset it to Disable.
3. The CPU fan is damaged, resulting in undetectable results; Just replace the CPU fan.

Press the del key to enter the BIOS at boot, set the default value to load in the BIOS, press F10, press Enter, which means to save and exit next time it will not be.
The load default option is the one that says "load.".What is the setting, remember the English at the beginning, find and select it.
-
The CMOS battery is dead, just replace the battery.
-
Enter the BIOS, press F7, and then press Enter on F10 to try it.

One. The motherboard battery is low or damaged.
The motherboard battery is used to ensure the motherboard BIOS power supply in the case of computer power failure, so as to save the user's BIOS setting information, once the motherboard battery is low or damaged, the system will appear relevant prompts asking you to solve, in the case of unsolved will prompt you to press F1 to continue, this is to ensure that the BIOS information will not be lost.
Solution: Replace the motherboard BIOS battery.
Two. The system hard disk is damaged.
When prompting 3rd master status bad backup and replace, it means that the system has detected that the third hard disk of the computer is damaged, it is recommended that you back up important data in time, and when this problem is not solved, you will also be prompted to press F1 to continue.
Solution: Back up the important data of the hard disk first, and then replace or repair the hard disk.
Three. The CPU fan is not functioning properly.
If you continue to run the CPU because the temperature is too high, it may cause you to freeze, blue screen, burn, etc., before the problem is solved, you will also be prompted to press F1 to continue.
Solution: Open the chassis, check whether the CPU fan is not working properly, and report for repair or contact the repair station.

Errors (such as a string of numbers, unreadable memory, etc., or unsuccessful loading) in the middle of boot boot are usually due to file loss or incomplete uninstallation of software, residual registry or viruses.
Make a note of the file name that went wrong, press regedit in the start menu, open the registry, and look for the error name (e.g., delete all found keys, and restart the computer.
In the start menu, run msconfig enter, remove all (except ctfmon) checkmarks in the startup and try to save and reboot (this can also speed up the boot of the computer).
If you don't know the child to enter safe mode, run msconfig enter in the start menu, and remove all (except ctfmon) checkmarks in startup to save and reboot.
If you lose a file or the file is corrupted and cannot be started, it is generally necessary to reinstall the system, the file is not lost or the file is not corrupted using the above method.
Type regedit in the start menu, search, delete all found keys, and restart the computer.
Or run msconfig in the start menu, press enter, and remove all (except ctfmon) checkmarks in the startup to save and reboot (this can speed up the boot of the computer).

Go into the BIOS settings and boot from the hard drive.

The reason is that the battery is short-circuited due to changing the hardware, which causes the CMOS parameters to be lost and inconsistent with the actual hardware.
1. Press F1 to continue, but next time.
2. Press del to enter the CMOS settings, set the date and time correctly, and modify the parameters that are inconsistent with the hardware, such as: the floppy drive is not actually there, but it exists in the CMOS, etc.
3. If you just don't want to get out of this interface, just set Halt On to No Errors in the BIOS standard settings.
Problem analysis: The computer automatically enters the CMOS interface of the motherboard when it is turned on, if you rule out human error to enter (you can press the ESC key to exit), it means that the computer fails to pass the self-test when it is powered on, which is generally a CMOS parameter error or hardware failure. Common phenomena include battery failure, misconfiguration, poor memory or hard disk contact, etc., which need to be investigated one by one.
Solution: 1. Battery failure: cause the computer to call the default parameters of CMOS, if it is inconsistent with the local hardware environment, the computer cannot be started normally. You can purchase a motherboard battery to replace it, then turn on the computer and press the DEL button (F2 or other designated hotkeys for notebooks) to enter the CMOS interface, and reset the correct parameters, and finally press F10 to save and exit the reboot.
2. Configuration error: This situation will also occur due to the manual configuration of CMOS parameters that do not match the local hardware environment. In general, you can press the F1 key to skip the non-fatal error and start the computer directly according to the prompt message on the black background and white text on the screen, or press the del key to enter the CMOS, then press F9 to load the predefined parameters or select Load optimized defaults or load fail-safe defaults, and then press F10 to save and exit the restart.
3. Hardware failure: If the above operations are invalid, it means that there is a problem with the hardware, generally because the memory and the hard disk are in poor contact or the hard disk master boot record is damaged, and the memory or hard disk needs to be reinserted and unplugged, or the hard disk master boot record is repaired or the system is reinstalled or the hard disk is replaced.

That means your motherboard is not compatible with the new CPU, in which case, if you want to upgrade, you have to change the motherboard. However, the current computer is not expensive, and it is better to buy a new computer in one step to change the motherboard.
Core 2 Duo T5200 is the heir to the Core Duo T2050, but we found that the Core 2 Duo T5200 has strong performance, but it is not comparable to the Core Duo T2050**, the king of cost performance, it still seems a little reluctant for it. >>>More
It depends on the situation, it depends on which disk your information is in, if it is not in the C disk, then there is nothing to worry about. If it's on a C drive, it depends on your CPU and motherboard. It turned out to be AMD's CPU, and now the board is changed, and it is estimated that the system has to be made. >>>More
It's that the CPU and the motherboard don't match, if you can't hear the "Didi" two or three sounds after powering on, it means that the motherboard can't turn on, of course it's not displayed.
