CPU Failure Resolution

IBM products are the main bar. As early as the Pentium motherboard bus frequency has 50.60.66MHz three kinds, The frequency of the PENTIUMCPU is generally 75.90.100.120.133.150.166.200.233.266.300.MHz. Motherboard and CPU speed is different, in order to coordinate the speed between the two, in the motherboard generally there is no "frequency multiplier factor" Jumpers are used to set the multiplier relationship between the two, currently popular motherboard frequency and CPU frequency.

　　Below say the motherboard and CPU frequency! Rate of the "multiplier factor" of the relationship above (unit: MHZ);

1. Phenomenon: In order to improve the system performance, try to choose a higher frequency of the motherboard, such as 66mhz.100mhz motherboard. In the selection of 66MHZ motherboard, CPU frequency can not choose 120.150MHz, should choose 100.133.166.200MHz Motherboard. When installing CPUs and motherboards , you should carefully look at the CPU and motherboard instructions, to find out the relationship between the two and the motherboard related to the jump on the location, but P133 CPU, by the motherboard bus frequency from the original 133MHz to 166MHz. Overclocking for a period of time, in the WIN95 system, the use of a disk crash phenomenon, And in the DOS environment a disk can be used normally. Why?

Solution: In DOS a disk can be used normally, can eliminate the floppy disk drive failure, may be CPU overclocking operation caused by the problem. Follow the instructions in the motherboard to skip the CPU back to 133. The problem will not come again.

　　2. Phenomenon: Sometimes the computer for a period of time the noise is particularly large, check the power of the fan, and no fault, do not know where the sound from?

Solution: Due to the use of the CPU for a long time, dust long-term accumulation of rotational speed, noise, reduce heat dissipation performance, you can remove the dust fan, in the fan shaft in a few drops of lubricating oil, the fault can be ruled out.

　3. Phenomenon: The computer 2 strips of memory to upgrade to 2 16M of memory, the start of the beep and no display, why?

Solution: The general computer beeps is the cause of memory, it is possible that the memory is not plugged in, caused by the black screen and no display, please check the memory, then you can troubleshoot.

　4, the phenomenon: the computer motherboard for the Op-ti chip, CPU is INTEL586/100, now buy Intel 586/166 generic CPU, open the chassis only to find that the motherboard on the CPU voltage switch only two. VRE (jumper for this machine) and STD, without a wide range of voltage options on general computer motherboards. If you do not change the CPU voltage, only change the CPU FSB and frequency multiplier will affect the entire hardware system operation?

Solution: There should be an impact. CPU voltage value is usually divided into three kinds of STD, VR, VRE, corresponding specifications are as follows:

STD:3.15--3.465V (recommended to set the motherboard voltage of 3.38V)

vr:3.300v--3.465V (recommended to set the motherboard voltage is 3.38)

VRE:3.450V-3.6 (recommended to set the motherboard voltage of 3.52V)

　　5, Phenomenon: How to overclocking the bus?

Solution: Simply speaking, the CPU frequency of the computer is this way; the frequency of the bus is equal to the main speed. such as P133 's operating frequency is: 66MHz (bus frequency) *2 (frequency) =133mhz. And most 430TX motherboards have the highest support 75MHz, Some motherboards can even support 83MHz to 100MHz, if your motherboard is just 430TX type, you can try to jump 75*2=150mhz the pleasure. But there is a need to remind, Overclocking will increase the calorific value of the CPU. and long overclocking may cause abnormal errors in the CPU, It is even possible to burn the CPU.

　6, the phenomenon: A Celeron CPU, from 266 overclocking to 333, you can use, but is sometimes suddenly inexplicable panic. Open the chassis, found that the video card, sound card is relatively hot, is estimated to be too hot and cause panic. I am afraid that overclocking will burn my board, what is the method to solve this problem?

Solution: After overclocking, the upper bus exceeds the prescribed frequency, resulting in the burden of video card or sound card, some quality is not very good board will be hot and burned, this is the consequences of improper overclocking. In this case, you can try the following two ways to resolve:

1 for the heat of the chip plus heat sink. The general graphics card, the sound card will not have the cooling measures, but you can buy a heat sink for it to install, so the effect will be much better. But keep in mind that the heat sink and chip should be tightly pressed together, do not leave any space, otherwise the effect, will be your board burned, because there is room in the middle of the air will play a role in insulation. It is best to apply some thermal silicon fingers between the chip and the heatsink.

2 Now the BIOS on the motherboard are energy management functions, it is best to start the function, so that the machine in the CPU more leisurely to rest, into the power-saving mode, which will make the temperature of the machine to a certain extent down.

　　7, K6-2 and Win 95

Phenomenon: My computer just upgraded to AMD K6-2/350mhz, the result system crashes. After you install Win 95, you will not be able to enter the system, prompting information as follows:

Device I/O failed to initialize. Windows Protection error. You must reboot your computer. Windows Protection error. Your must reboot Your computer. Replace the original CPU is all normal, is my motherboard does not support this CPU, or jumper has a problem?

Workaround: Please install win 98 or install the patch directly.

Step: Upgrade win 98 directly on the original CPU. Before you install Win 95, set the CPU to 100Mhz X3 (300Mhz). After installing the system and all the drivers, set the CPU to the original frequency.

Description: AMD K6-2/350mhz CPU and Win 95 conflict, so there will be the above phenomenon. The win 95 patch is not required to install Win 95 on an AMD Athlon CPU. Install Win 95 o'clock on the K6-2/400 CPU encountered an error message that interrupted the installation process.

　8, FoxPro run always error

Phenomenon: FoxPro is always an error in running high frequency machines.

Workaround: Use Gmstart.exe.

Step: Download the Gmstart.exe software on the Internet. Then add the Gmstart.exe run path before running the path in "target" in the properties of the FoxPro shortcut.

Description: Gmstart.exe Download URL: http://www.cfan.com.cn.

　9, about auto CAD R12 Chinese version

Phenomenon: My Lenovo Day Crane 620 computer in the running auto CAD R12 Chinese version of the error.

WORKAROUND: Spin down to run or upgrade to a later version.

Step: Use the Auto CAD R14 or Auto CAD R 2000 Chinese version or modify the computer's CPU settings, so that the frequency of 300MHz can make the software normal operation.

Description: The development of hardware is always ahead of the actual software products. On the one hand, some software requires a faster CPU, while on the other hand, some software is not suitable for new fast CPUs, such as Win 95 can not run on 350MB CPU. Auto CAD R12 Chinese version also software can not be in P 350 and higher frequency of the CPU running, the CPU speed reduced to 300 when the software is operating normally, this software on other models also.

　　10, unable to install the UNIX 3.2.4 operating system

Phenomenon: I want to install UNIX 3.2.4 version operating system on daily 1000/333 PCs, but fail repeatedly.

WORKAROUND: Please replace the new version of the UNIX system or LNUIX system.

Description: SCO company data shows that UNIX 3.2.4 version of the operating system, the highest CPU frequency supported by 200MHZ. Therefore, install this version of Unix on a computer above 200MHz, it will fail to install or run unstable, and can not play the reliability of Unix system.

　　11, frequency is sometimes automatically reduced

Phenomenon: After the boot of the original 166MHz CPU into 133, the information displayed is "Defaults CMOS setup Loaded", after the reset of the CPU parameters in the CMOS setup (soft jumper motherboard), the system normally shows 166 frequency, but not necessarily which day, Will repeat the above process.

WORKAROUND: Replace the CMOS battery.

Step: Turn off the computer and wait for the hard drive to stabilize and open the chassis. On the motherboard, find a mirror-like lithium battery with a button-shaped ink screen lid. One hand break the top of the battery of the single spring, hand down the battery lithium battery, the trend to insert new batteries. Turn off the computer, power on, reset the CPU and other parameters. Usually select "LOAD BIOS DEFAULTS", use a number of defaults, select "IDE HDD AUTO Detection", select 2, enter and press three ESC key to jump
