For most ordinary users, the chassis is not open for a long time, not to mention to the computer to do a clean, and now the weather is hot, many users began to find their own computer frequently crash, restart the problem-the accumulation of dust has been a long time to play the role of "insulation", the computer does not die to blame. Hurry up and pick up the brush and the fur tiger, let's make a clean of the equipment inside the computer
cannot read the disk after loading the chassis. After taking out again all normal. I've tried it so many times. Suspect is a chassis problem, after careful examination, troubleshooting is a chassis failure problem. Puzzled by the solution.
Remove the CD-ROM drive, take the hand over and over to see, did not find any problems. In the spirit of DIY and their own
⒈) Some computer chassis front USB connectors are not available
Have found many friends the so-called USB interface can not be used, only the user uses the USB interface on the front of the chassis, but the USB connector on the chassis is only available when the USB cable on the chassis is connected to the correspondi
failure may also be caused by the following reasons: First, the chassis power switch problems, such as reset spring failure, the second is the C p u for overclocking, or C p u fan problems. Third, the optical drive and other accessories have short circuit fault. computer power-on automatic power off problem 2: The computer turns off automatically after 10 seconds after booting. CPU and so on has cleaned up the power should be no problem because b
voltage is normal. After checking the peripheral components of the U5, we decided it was broken, and after replacing U5, the board returned to normal.
Instance 3. A gigabyte 6BXC motherboard is not lit, and is not even the power of the fan does not turn, the board has been repaired. Check the power switch tube does not penetrate, the chassis power supply ps-on end and the ground short connect to force the boot, the power supply is still not added. T
Computer motherboard overheating Solution:
The main reason for the motherboard overheating is the high calorific value of the video card and processor, and the heat in the chassis is not able to dissipate in time, the following measures can be taken to cool down:
1, inside the chassis and the motherboard dust more.
2, check the chassis ventilation channel is n
Computer flower screen, is generally direct and memory or explicit there is a direct relationship, and drivers sometimes have similar problems.
First, check the video card temperature is normal?
Can download a drive life, or some related software to check the test card temperature is normal.
When the graphics card temperature is too high, the computer often appears a lot of inexplicable fault, the flower screen is just one of the faults.
The video card is the most calorific value

Know that the chassis is part of the computer accessories, chassis generally include enclosures, stents, panels on a variety of switches, indicators and so on. The shell is made of steel plate and plastic, the hardness is high, which mainly protects the internal components of the chassis. The bracket is primarily used for fixing motherboards, power supplies, and
pursuit of stability, speed of the player or the love with the SCSI hard drive.
Hard drives with different SCSI specifications:
With 68-pins Wide SCSI connectors, you can transfer data using the 16-bit channel width.
With 60-pins narrow SCSI connectors, data can only be transmitted in a 8-bit channel width.
Jimper (jumper) settings, mainly used to adjust the ID of the hard drive, terminal resistor switches and so on.
SCSI hard drives are very expensive computer peripherals and you must be
Now, the computer is no longer entirely our office tool, after work, we through it to watch movies, listen to songs and so on. But sometimes when listening to songs or watching movies, suddenly the computer did not sound, let us helpless, how to do? The Windows operating system is lost in many cases due to the sound card and its drivers, and in most cases we can choose to reinstall the sound card driver, but this is not entirely the case. Here is a description of the Windows operating system oft
