After cleaning up the dust, it turns into a black screen. What to do

        1: self-cleaning dust computer black

Q: Not long ago replaced the CPU fan, but also for the host sweep dust. After the completion of the boot, the black screen, the specific phenomenon is as follows: start direct black screen, nothing is displayed, then the motherboard's battery is removed and installed, you can see the motherboard's logo, you can enter BiOS; in the self-test process, self-test After "CheckingforCD-ROM", it will be black; set the CD-ROM drive to boot, put a CD, start the computer or black screen.

system House A: If you have not changed the jumper around the BIOS chip, nor upgraded BiOS, self-test to "CheckingforCD-ROM" on a black screen, usually memory related. Especially if the memory is not well connected, or there is a compatibility problem, it is easy to show this prompt during the startup process. Since it is a fault after replacing the processor fan, it is likely to be a memory contact problem. It is recommended to remove the memory and use the eraser to brighten the gold finger of the memory module and repeatedly insert and pull for testing.

2: support for the DDR2 memory type DDR3 motherboard can plug in memory cards do

Q: My motherboard supports memory types DDR2, DDR3 memory I can plug in the card you ? In addition, my graphics card also supports TC technology, you can call system memory. Will this issue be caused by compatibility issues? Why is it always a sudden crash?

system House A: DDR3 video memory can be used on the motherboard supports DDR2 memory, and there is no direct relationship between the two. We can simply understand these relationships: the memory is plugged into the motherboard, what kind of memory is related to the chipset on the motherboard. The memory chip is soldered to the graphics card. What kind of memory is supported, only related to the graphics card core. This reader can rest assured that the graphics card with DDR3 memory is OK, as long as the relationship is clear.

In addition, TC technology may invoke the use of system memory as video memory, but does not specifically requested the same type of video memory and system memory. If the TC function is always restarted after a sudden crash, it should be a driver problem. It is recommended to install the latest version of the graphics card driver.
