Is usually not, namely power lights, fans listen to, it doesn't start up, if it is not up, all the wiring plug-in picked, just try to minimize the memory on the boot, if Windows is launched, even have heard loudspeaker Windows startup music, is that the monitor plugged into the wrong interface, see behind several shows, change a try?

Don't know if your hosts have little horn, under normal circumstances self-check will hear drops a self-check on computer after normal boot, if there is no voice, priority judging is memory problems, if there is excess is the memory, can change to the computer to test,

CodePudding user response:

Have 2 computer memory, you can unplug one root test whether to boot! Pull the other one to do one test!
And case there is a computer graphics, the display of the cables on the interface of integrated graphics, also can appear this problem,

CodePudding user response:

Memory problems, this kind of circumstance is usually memory, what do you mean by the host running normally, just on the electricity. The fan in turn, the system does not start

CodePudding user response:

host chassis lid open, switch on the keyboard again wait a little keyboard can't be bright together, if you can suggest check display or VGA line, or the wrong card interface (received integrated graphics), if there is no bright together, suggest install only a piece of memory chips, and the host discharge (disconnect the power cord, VGA line, the remove button batteries), is not only to send again,
