1. Wind direction problem. ATX chassis. The CPU fan is blowing toward the CPU. The power fan is blown outward. The front panel fan of the chassis blows in the inner, and the chassis rear panel fan is the same as the power fan, blowing.
2. The main source of machine noise is the power fan and CPU fan. The CPU fan is fixed with the heat sink, causing a lot of noise, it is recommended to replace the entire heat sink directly. 10 heat sinks of 10 yuan, noise is relatively large. Make together.
3. When the fan turns, don't take a screwdriver in the nearby drum! Lesson, lesson. . .
4. That kind of oil × × fan, the time can take oil. Edible oil is also possible.
5. The optical drive's jumper can temporarily hip the hard disk.
6. Hanging on the machine to temporarily unused the data cable, not a power cord. Otherwise, it is possible to turn on the IDE device very slow, for example, two hard drives are set to the primary disc.
7. Award BIOS alarm code:
1 Short: The system starts normally. Congratulations, your machine has no problem.
2 Short: Regular error, please enter CMOS Setup, reset the incorrect option.
1 length 1 short: RAM or motherboard error. Try a memory, if it is still not, then replace the motherboard.
1 length 2 Short: monitor or display card error.
1 length 3 short: keyboard controller error. Check the motherboard.
1 long 9 short: motherboard Flash Ram or EPROM error, BIOS is damaged. Change the block Flash Ram to try.
Constantly no sound (long): The memory bar is not inserted or damaged. Reversion of the memory module, if it is still not, only replacement of memory.
Repeat short noise: There is a problem with the power supply.
No sound No display: The power is problematic.
Below is the AMI BIOS alarm code:
1 Short: memory refresh failed. Replace the memory module.
2 Short: memory ECC is more effective. Setting the memory of the ECC check in CMOS Setup to disabled to solve, but the most fundamental solution is still replaced by memory.
3 Short: System Basic Memory (1st 64KB) check failed. Change memory.
4 Short: The system clock is wrong.
5 Short: Central Processor (CPU) error.
6 Short: Keyboard controller error.
7 Short: System real mode error, cannot switch to protection mode.
8 Short: Show memory errors. There is a problem with the memory, replace the graphics card.
9 short: ROM BIOS test and error.
1 length 3 short: memory error. Memory is damaged, replaced.
1 length 8 short: Show test errors. The display data line is not plugged or the display card is not pulled. 8. The XP mode is calculated based on the version of XP, HOME, PRO, VLK, PRO SP1, VLK SP1, etc. If you don't want to count, you can search directly online. VLK is also an example. If you upgrade or fix XP, you may ask for the original CD-KEY, and there is no reloading. When doing system disks, CD-KEY should be provided in the disc.
