1. If there is no problem with the graphics card, I feel that I can unplug it and put it in the graphics card slot for maintenance (I haven't met it yet, because most desktop computers have PCI slots for expansion.)
2. Generally speaking, a computer that can be used normally inserts a hardware into PCI. When it is turned on, it will prompt to install driver for the hardware or install driver automatically.
3. At present, there is no motherboard that can detect PCI slot with software without inserting anything. You can spend 10 yuan to buy a computer diagnostic card. At present, the most efficient detection method is to use this diagnostic card to detect the quality of PCI slot
first of all, you plug the diagnostic card into the PCI card slot on the motherboard. There is an LED screen on the diagnostic card, and the numbers will show different definitions:
there are three cases of special codes "00" and "FF" and other starting Codes:
① a series of other codes are followed by: "00" or "FF", Then the main board is OK (this can prove that your PCI slot is good)
② if no error is set in the CMOS, the minor fault will not affect the BIOS self-test, and eventually "00" or "FF" will appear
③ the board is not running when "00" or "FF" or other start codes appear and do not change
bonus points

4. Are your three PCI slots empty or are all plugged in? If they are full, please go to the device manager to see if there are any question mark or exclamation mark devices. Please re install the driver
try to restore the CMOS settings again to see if it works. In fact, the motherboard hardware problem, can only go to the computer city repair, circuit problems or to universal meter to find out, generally can not determine is a capacitor, resistance or integrated chip.

5. Pci-e2.0 has the same appearance as the old interface. Pci-e2.0 data transmission rate of each serial line has been increased from the original 2.5Gbps to 5Gbps, and the power supply capacity has been greatly improved. Many graphics cards used in the old interface do not need external power supply after being inserted into the new interface, so you can think it is the speed upgrade version and power supply capacity upgrade version of pci-e1.0. In terms of compatibility, pci-e2.0 can be downward compatible. In other words, pci-e2.0 graphics card can be inserted into pci-e1.0 slot, and pci-e1.0 graphics card can also be inserted into pci-e2.0 slot. In terms of performance, as long as the transmission bandwidth of the new graphics card does not exceed the bandwidth provided by the old interface, no matter which version of the interface the new graphics card is inserted into, the performance will not be lost.
6. This, please download SLI cracking tool, because amd motherboard does not support SLI, to crack
7.
Generally, there are expansion slots on the computer motherboard to install independent graphics cards, which are divided into PCI, AGP and PCI-E, as shown in the figure:
in the gpu-z figure, the graphics card bandwidth is directly above the graphics card interface column, so you can clearly see what slot the graphics card is
8. Installation of 360 security guards, scanning system can coagulate files, real-time protection system
restart the computer and enter BIOS to restore the default BIOS settings
format the partition of the system and re install the operating system
open the chassis and check whether the power supply of the chassis is abnormal
try changing the brand power supply. If not, there may be a problem with the motherboard.

9. If the service time is short, consider the connection or setting failure. If it is used for a long time,
hardware failure is considered, and internal voltage instability is common. Whether there is lightning strike before the fault occurs, and whether the strong current is wrongly connected to the weak current port, etc
you are not an expert. You'd better not try to solve it yourself.

10. The possible reasons for the automatic restart of the computer. When the network becomes the information artery of today's society, the spread of the virus is more convenient, so it also interferes and destroys our normal work from time to time. A typical example is the "shockwave" virus, which has caused serious damage to computers around the world some time ago. When it breaks out, it will prompt that the system will start automatically after 60 seconds. In fact, as early as the DOS era, there are many viruses that can automatically restart your computer
* * for whether it is virus damage, we can use the latest version of anti-virus software for anti-virus, and generally find the existence of virus. Of course, there is also a possibility that when you surf the Internet, someone has maliciously intruded into your computer and placed a Trojan horse program. In this way, the other party can remotely control all the activities of your computer, including the restart of your computer. For some Trojans, it is not easy to clear, it is best to re install the operating system< When the system files are damaged, such as kernel32.dll under Win2K, fonts under win98fonts, etc., the basic files of the system run time are damaged, and the system will be forced to restart because it cannot complete initialization. You can do an experiment, the Win98 directory font renamed try. When you turn it on again, our computer will start again and again
[< 3. Timing software or task scheling software works
* * * if you set up to restart or load some work programs in the "schele taskbar", when the timing time comes, the computer will start again. In this case, we can open the "start" item to check if there are any unfamiliar executive files or other timing programs in it, and then turn it on again after shielding it. Of course, we can also directly enter the "msconfig" command in "run" to select the startup item< 2. Hardware
} 1. The mains voltage is unstable
* * * the working voltage range of switching power supply for general household computers is 170V-240V. When the mains voltage is lower than 170V, the computer will automatically restart or shut down. Because we sometimes can't feel the fluctuation of the mains voltage, we will mistakenly think that the computer will restart automatically for no reason
[< 2. The quality of plug or socket is poor, and the contact is poor
* * most of the power plug on the market is poor, and the internal contacts are manually welded, and acid flux is often used, which easily leads to the oxidation of solder joint in the future use, causing open circuit or leakage between live wire and zero wire. Because of manual welding and poor elasticity of phosphor brass sheet, it is easy to lose its elasticity in a short time, resulting in poor contact with the power plug of the host or display, resulting in large contact resistance. When working for a long time, a large amount of heat will be generated, resulting in virtual connection. At this time, the host will restart or the display will flash black screen
* * another possibility is the wall sockets used in our home. Most of the wall sockets are not installed by professionals, so the internal wiring of the sockets is very nonstandard. Especially, if we often use high-power electric heaters, these sockets will easily lead to internal heating, oxidation, virtual connection and intermittent power failure, Causes the computer to restart or the monitor blinks
[
(2) for the problem of virtual connection inside the wall socket, we can try to replace the host with a wall socket to see if there is the same problem of automatic restart< 3. The power of the computer power supply is insufficient or the performance is poor
* * this situation is also common, especially when we add new equipment to our host, such as replacing the high-end graphics card, adding the recorder, adding the hard disk, it is easy to appear. When the host is working at full speed, such as running a large-scale 3D game, recording at high speed or preparing to read the CD, when it is just started, the double hard disks the data, which may cause the power protection to stop output e to the lack of instantaneous power supply. However, when the power supply stops output, the load will be reced, and then the power supply will start again. Because the recovery time after protection is very short, our performance is that the host restarts automatically
* * there is another case, which is the poor performance of the host switching power supply. Although the voltage is stable and within the normal allowable range, because the harmonic content in the output power supply is too large, it will also cause the host to crash or restart frequently. For this case, we use a multimeter to test its voltage is normal, it is best to replace a good power supply to replace the exclusion
[< 4. The mains plug of the host switching power supply is loose, the contact is poor, and it is not tightly inserted
* * most of these cases will appear on DIY machines. The power cord of the host power supply has not passed 3C certification, and it does not match the power socket. When we shake the table or touch the host, the host will restart automatically, usually accompanied by a slight electric fire
[< 5. The power supply atx20 socket of the motherboard has false welding and poor contact
* * * this kind of fault is not common, but it does exist. The main reason is that when the host is working normally, move the atx20 pin plug left and right to see whether the host will restart automatically. At the same time, check whether the spring inside the 20 pin power plug is oxidized, which can easily lead to high contact resistance and poor contact, causing the host machine to crash or restart. Sometimes it is necessary to check whether the connecting wires at the tail of 20 pin plug are reliable
[. Note: when welding motherboard, hard disk, graphics card and other computer boards, make sure the electric iron is well grounded, or pull out the power plug when welding
(2) if it is a power supply problem, it is better to replace a good power supply
} 6. CPU problem
* * when some function circuits inside the CPU are damaged, and the secondary cache is damaged, the computer can start, and even enter the normal desktop for normal operation, but when a special function is performed, it will restart or crash, such as drawing tables, playing VCD, playing games, etc< Solution: try to shield L2 or L1 in CMOS to see if the host can work normally; Another way is to replace and eliminate the CPU directly. If the shielding can work normally, you can still make do with it. Although it is slower, it will save money
} 7. Memory problems
* * if a chip on the memory mole is not completely damaged, it is likely to pass the self-test (most of them have set post), but it will cause the function failure and restart unexpectedly e to the high heat of the memory. Most of the time, when the memory is damaged, the boot will give an alarm, but when the memory is damaged, it will not give an alarm, and there are still some faults without power on. It is better to use the elimination method, which can quickly determine the fault location< If the CD-ROM is damaged, the host will start slowly or fail to pass the self-test, or it may restart suddenly in the working process. For the latter case, if we replace the optical drive, it is likely that the power consumption of the optical drive is different. What you need to understand is that although the ATPI interface of the optical drive is the same, the pin definitions of different manufacturers are not the same. If there is a problem with our hard disk cable, there may be a situation that there is no problem with the use of a certain brand of optical drive, but there is no problem with the use of other brands of optical drives. This needs your attention< If the reset switch is damaged and the internal reed is always in the short-circuit position, the host will not be able to power on and self check. However, when the elasticity of the reset switch is weakened or the button on the chassis is not easy to pop up when it is pressed down, it will appear in the process of use, because the chassis is touched occasionally or the host suddenly restarts in normal use. Therefore, when the reset switch can't be pressed freely, we must check it carefully. It's better to replace a new reset button switch or lubricate the external buttons of the chassis
* * there is another case, because the insulation layer of the reset switch lead in the chassis is stripped too much ring welding, and the reset switch lead is too close to each other e to multiple unpacking ring use, resulting in collision and automatic restart of the host< When the network card or parallel port, serial port or USB interface is connected to the external device, it will restart automatically.
* * this situation is generally e to the failure of the peripheral device, such as the damage of the parallel port of the printer, the short circuit of a pin to the ground, the damage of the USB device to the ground, the nonstandard network card work, etc, Will cause the computer to restart because of the sudden power short circuit. Third, other reasons
} 1. Poor heat dissipation or temperature measurement failure
* * CPU poor heat dissipation. The common problems are that the fixing clip of CPU radiator falls off, there are foreign matters between CPU radiator and CPU, and there is too much st on the radiator after CPU fan is used for a long time, which will lead to poor heat dissipation of CPU, The accumulation temperature is too high to restart automatically
* * there is also the damage of the temperature probe under the CPU or the internal temperature measurement circuit of the p4cpu, the BIOS on the motherboard has a bug, and the temperature measurement is not accurate under a special condition, which will cause the host to restart automatically and protectively in the working process< Finally, if the CPU protection temperature set in CMOS is too low, the host will restart automatically< When the speed measuring circuit of the CPU fan is damaged or the speed measuring line is intermittently open, because the main board can not detect the fan speed, it will mistakenly think that the fan will stop and automatically shut down or restart, but we may see that the CPU fan operates normally and the speed measurement is also normal< 3. Strong magnetic interference
* * Don't underestimate electromagnetic interference. Many times our computer crashes and restarts are also caused by interference, which comes from
* * for whether it is virus damage, we can use the latest version of anti-virus software for anti-virus, and generally find the existence of virus. Of course, there is also a possibility that when you surf the Internet, someone has maliciously intruded into your computer and placed a Trojan horse program.
