BIOS settings cannot be modified, etc question and answer 5

The reason why computers often restart

Q: The Computer configuration is: MSI 865PE motherboard, P4 2.8GHz CPU, Seagate 120GB Hard Drive, two 256MB Kingston DDR400 memory, GeForce FX5600 video card, installed is the win XP operating system. Since last year bought back after the restart phenomenon has not been interrupted, Zeng installed several systems, but also replaced the motherboard, but the problem is still, what is the reason?

A: No reason to restart is the computer use of a very common fault, this fault and a number of factors related to the removal of the system has problems or virus and other software factors, hardware quality problems or poor compatibility is the main reason, especially in memory, power and motherboard, such as three major accessories suspect the most. Because you have replaced the motherboard, it is best to replace a better quality of the power to try. If the problem persists, you can download and refresh the corresponding motherboard BIOS program on the MSI website, if you still can't switch to another brand of memory to try.

In addition, now the CPU, display chip calorific value is very large, if the heat dissipation, temperature is too high, may cause the system to restart frequently, such as CPU fan or video card fan speed down or even failure, may cause the system to run unstable or even restart.

The system always jumps back to the desktop while playing the game

Q: The computer configuration is as follows: Athlon XP 2500+ CPU (Barton Core), KT600-C1 motherboard, Kim Bang 256MB DDR400 memory, Xiang Sheng GeForce FX5600 Standard Version graphics card, Seagate 80GB hard disk, technical display chassis power supply (nominal 300W) , the Win2000 SP4 and WinXP SP1 Dual systems are installed. As long as the computer play "Red Moon" and other large 2D network games, always suddenly jump back to the desktop, simply can not play the game! Friends say power is not enough, I in the BIOS in the "Fast Write" and memory SPD option to turn off, but the phenomenon remains. What's the reason?

A: The first thing to make clear is that just turn off the "Fast Write" and the SPD option in memory, and not reduce the amount of actual power consumption. The author of the first two days just met a case with your configuration is basically the same and the fault phenomenon is basically similar to the computer, has replaced a brand power, a motherboard and a memory, the result is still the problem. The video card is then replaced, but the problem remains the same. Finally replaced a great Wall 300W power supply, the problem can be solved. After analysis should be the power quality is not clearance, resulting in insufficient power supply, only to appear above the fault phenomenon!

What to do if the options in the BIOS are not modified

Q: A computer to download a file from the Internet, download when the system prompts this file may damage system files, then did not care, the next day will not be able to enter the system. It was intended to change the boot disk order by modifying the BIOS to reload the system, but the contents of the BIOS could not be changed except for the user's password (previously available). Is my computer infected with the virus?

A: It is estimated that you download malicious programs or viruses in your files, modify some settings in the BIOS, or add some error codes to keep the BIOS from being modified, but now that the computer is still able to boot, the BIOS has not been completely compromised. The solution is to completely empty the BIOS, the specific method is: first open the computer chassis, and then follow the instructions on the motherboard, find the BIOS discharge jumper, and as required to set it to discharge status. After a period of time to restore it to the normal state and power on the boot, after the normal boot into the BIOS setup program, and then correctly set the boot disk sequence, save the exit restart after the computer, under normal circumstances can be ruled out.

Why can't I find a USB hard drive

Q: Recently I bought an IBM USB2.0 interface of the mobile hard drive, under WIN98SE and WinXP can find a new USB mobile hard drive, but the requirements to install drive, installed after the driver needs to restart the computer, but the restart is dead, can not pass the self-test. Unplug the USB cable, the computer can start normally, enter the system and then connect to the USB mobile hard drive, can not find a USB mobile hard drive, but the USB flash exists on my computer on the normal use. My computer is configured as: Intel original i850 motherboard, P4 1.5GHz CPU, two Rambus 64MB memory (altogether 128MB), GeForce2 MX200 video card. This IBM mobile hard drive works on other computers. Excuse me, what's going on here?

A: Your USB flash can be used on your computer, indicating that there is no problem with the USB interface of the motherboard. This IBM mobile hard drive works on other computers, indicating that the mobile drive itself is not a problem. Unplug the USB cable, the computer can start normally, do not pull the panic, indicating the operating system and hardware drivers conflict. The solution is to reload the USB2.0 drive, whether it is Win98SE or WinXP, and it is best to use a USB device with its own installation drive. Do not know your WinXP version is how much, if not WinXP SP1 version, it is best to upgrade to WinXP SP1.

Also note that you should install the motherboard driver first before installing the USB device driver. In addition, if you are the USB hard disk to the front USB interface, it is best to switch to the rear USB interface, so as to avoid the connection of the front USB connection error caused the problem.

CPU fan speed not shown in BIOS

Q: I bought the boxed CPU P4 1.8GHz, in the BIOS display "CPU FAN speed:4017 rpm", after a period of time, found that the CPU fan noise, a bulk of the CPU fan after the review BIOS information, found that the system does not detect the speed of the CPU fan , the BIOS "CPU FAN Speed" is shown as "CPU FAN speed:0 rpm". Excuse me, what is the reason?

A: The power cord for the boxed CPU fan is three lines, in addition to the power supply, but also through the sensor to the CPU fan speed to the motherboard, so the motherboard can show the speed of the CPU fan, but now the market some of the bulk fan power cord is two lines, and some even three lines but does not have the sensor function, Therefore, the motherboard BIOS will not be able to display the fan speed.
