The host computer is on, but the monitor shows no signal. What shall I do?
First of all, make sure that the host is not running properly. If the host does not start properly, then how does the monitor display that?. If the host is clear and normal starts, check the monitor line. If the host doesn't start properly, then try to plug in the memory card again and try again.
Good check, the connection is no problem, it should be memory, or CPU did not plug, from the new plug should be good, not good, it should be the motherboard thing
Encountered, harm, I took the computer several times, ah, how to clean all can not, and finally downloaded a video card driver is good, the original video card comes with the CD is part of the damage!
Try to solve the problem in the following aspects:First of all, to determine whether the display problem or host problem, the monitor connected to other computers to try, OK, then the host problem, not yet, then the display problem1, display problemsCheck that the electrical outlet is energized, check whether the connection line interface (VGA or DVI interface) is connected (important), and if necessary, try another line2 host problems1) check the graphics card is inserted or loose, the fan does not work properly, clean up the dust on the interface, try the latest video card driver2) the whole machine cleans the dust, keeps it cool, and kills the virus.3, on the test can not, can reinstall the system to see.Still can not be recommended to repair
