How to solve the panic caused by the hardware cause

1, CPU

The CPU is overclocking, overheating, or the core voltage is set too low, the CPU is working properly but the temperature of overheating protection is set too low.

Overclocking can greatly improve the processing speed of computers, but at the same time it may cause the CPU to become unstable. If your CPU is overclocking, try it back to the default frequency first. Open the chassis check the temperature of the CPU heatsink is too high and the heatsink is loose. Under normal circumstances, hand touch CPU heatsink should feel warm and not hot.

To ensure that the CPU operating temperature is normal, to see the BIOS in the CPU overheating protection of the temperature value is set too low. When the motherboard detects a higher CPU temperature than the protective device setting, the system shuts down or resets automatically. For example Pentium 4 and 0.13um process of Athlon XP, generally set between 60-70 degrees on it. Set too high will lose protection, too low will cause the system mistakenly thought that the CPU overheating and "strike."

For Duron, Athlon XP and Celeron 2, Pentiun III processors, also note that the CPU's core is intact, whether or not the heatsink is crushed. This also reminds us to install these CPUs, we should pay attention to the proper and even force, do not pressure bad CPU core cause hidden trouble.

2, Memory

In fact, most of the computer failures are memory problems. There are mainly loose memory, poor contact, compatibility problems or the quality of their own problems, there is the voltage and frequency is not properly set (voltage is not enough or too high frequency).

If the computer just moved from another place, it is very likely that the removal of the memory in the process, you can open the chassis to slightly press it tight, or simply pull out the plug. If the computer used for a long time, it may be the dust caused by poor contact, can be slightly hard paper to the memory of the gold finger wipe, while the memory slot in the dust blown away, the memory of the dust gently brush with brushes and other soft brush sweep off. If it is a new machine, it is possible that the voltage and frequency of the memory are not set correctly.

Now DDR400 memory is becoming more and more popular, some friends may not know, DDR400 specification of the memory to run stably on 400MHz, need 2.6V voltage, and DDR266 specifications to stable operation in 266MHz, only need 2.5V voltage. Many motherboard factory defaults are 2.5V, if your DDR333 or DDR400 memory to run in 333MHz or 400MHz, you need to change the memory voltage 2.6V (some motherboards are automatically recognized). I have seen a machine, Kingmax DDR400 memory running on the 333MHZ (each parameter is the SPD default), but always panic. After inspection found that the motherboard voltage jumper is jumped 2.6V, but the BIOS shows only 2.49V, and finally to jump to "2.7V", the BIOS only shows 2.59V, the machine is stable.

Many installed in the assembly of computers, do not know is not understand, forget or too troublesome, did not change this setting, running small software to see the problem, a play game is over. So, I'd like to remind you to pay attention.

In fact, the memory voltage is slightly higher than the standard voltage high 0.1v-0.2v generally is no problem, but pay attention to heat. Some motherboard manufacturers are secretly in memory, AGP and North Bridge chip power to add a little bit of voltage, so that their products look more "stable."

3. Hard Drive

Mainly the IDE data cable damage, hard disk aging or due to improper use caused bad, bad sector and so on. Generally, you can change the IDE data cable to try first. If not, it is the problem of the hard disk itself. Once the hard drive is running, it crashes when it reads bad and bad sectors. There is the mechanical failure of the hard disk, this fault is often a precursor, such as hard disk from time to issue a larger noise, post to the hard disk when the crash or peacetime panic accompanied by a larger "giggle" sound. When this happens, it is best to back up the useful data immediately and send the hard drive to repair.

4, graphics card

If the panic occurs more in the running of 3D games, the video card is also a large suspect. Check whether the video card is plugged in, can be a little hard to press the video card, but also pay attention to whether there is a certain part of the video card is particularly hot, some words can first try to increase the heat dissipation fan, it is really hot words on the 90% graphics card problem. In general, you can only send the graphics card repair.

5, Motherboard

The main is to pay attention to whether there is no AGP, USB and other interface power shortage. The author of a classmate of a Lenovo P4 brand machine has appeared this problem. Motherboard using I845D chipset, with Geforce4 TI4600 replace the original Geforce2 MX400 video card, the game occasionally appear in the phenomenon of flower screen, sometimes just post will also flower screen. At first thought is the problem of graphics card, looking for merchants to change the two or not, and finally get a piece of nforce 2 Ultra400 motherboard on the completely normal.

There is to check whether the phenomenon of virtual welding. This is mainly due to the installation of other boards too rough or improper force caused.

Can be in the light to check the solder joints have no loose, solder on the "Black Circle."

6. Power supply

Power is the normal operation of the computer is the basis, but the power is also the most easily overlooked. If the new or newly upgraded computer, you should consider whether there is a problem of insufficient power. The main performance is to read any disc is easy to panic, boot sometimes because the hard disk can not find the system hangs (the possibility of troubleshooting hard disk or optical drive). If you have more than one hard drive, try unplugging the "redundant" hard drive first.

Also once encountered such a fault, buy back a DVD-ROM, read CD is nothing, a read DVD disc on the panic. After inspection, originally with a 60 Yuan "350W" power, weighing in the hands of the two Zhang Xianka than the weight of the same, and then changed to a great Wall power supply is good.

There is the power of the anti-interference ability of the problem. Now home has a lot of household appliances, especially the inverter air-conditioning, washing machines, microwave ovens, and so on, they start the instant will produce a larger pulse, power anti-interference ability, will cause the output of the current clutter, and even voltage changes beyond the hardware can withstand the range and "strike."

7. Hardware resource conflict

This kind of malfunction is more common in older computers, and the newest machines are rarely present. Mainly due to the sound card, network card, modem and video card settings conflict, causing abnormal errors. For example, IRQ conflicts, DMA conflicts. This failure, can first try to restore all the BIOS settings to the default, and then no longer need to manually allocate the words, this is more complex and need some experience, this article does not elaborate, there is a need to query the old point of the computer magazines and newspapers, generally have a detailed introduction.

8, chassis

Poor chassis can make each hardware installation not in place, resulting in poor contact. This situation is the most troublesome, do not want to change the chassis, you can only use their hands to try to break, see whether in place. In addition, to deal with this type of chassis, graphics cards, such as expansion cards are not fully tightened, but to pad some paper to the position of the screws on the screw, this will make contact better, you can also avoid forced installation of damaged hardware.

In addition to the above mentioned, there are some easily overlooked details. For example, the data cable and power cord in the chassis, preferably bundled rather than scattered in the chassis. This will clog the inner air duct, and may be mixed to the CPU fan, causing the CPU fan to stop and damage the CPU. A friend of the author has ever had such a thing. His machine is a legend die, after inspection, because the motherboard's power interface from the CPU fan is very close, the motherboard power line is not tied up, completely blocking the CPU heat sink a surface, which caused the CPU overheating and panic.
