Boss's computer is out of orderHold me here, redo the systemAfter leavingMy host can boot, but the monitor is not bright (no hint without signal, unplug from the host prompt),Keyboard, mouse is not bright (no response in any case)(without any hardware changes, it's normal to plug my host back once in the process of the fix.)CPU fan runs normally without alarm soundDisassembly, dust removal (memory, CPU, and dust on each interface) do not workIt's not a software problem, a system problem, a virus problemPlease answer the questions of the experts carefully look at my questions, and what I did not describe, I would like to addPlease master to help me analyze, thank youCopy the answer, don't come, I won't see it
Check whether the boot is through self checking, beep sound, if not, you can determine the basic memory problems, use the eraser to wipe the finger part of the side, if there is a "beep" sound, if your motherboard integrated graphics, the display line inserted into the integrated graphics card test under the
Keyboard, mouse is not brightDescription is the host of the problem, you put the graphics card, memory, these new plug in to see, no, then change the power supply, not to change memory,
It's probably the motherboard problem! Discharge the battery on the motherboard for an hour! Then put the battery up and turn on and see if it's ready!The motherboard has BIOS, and may be a problem with a set! After the main board of the battery discharge, the motherboard will restore the default state! Boot is normal!
Computer boot is just fan turn, the monitor does not respond, certainly there is a problem with the computer hardware, it is best to use the replacement method, troubleshooting, judgment methods:1, press the button on the keyboard to open the key. Light shows that the graphics card, monitor, other hardware and other failures.2, the keyboard does not light, indicating memory, CPU, motherboards, or power issues.Resolvent：1, the keyboard light is not bright, first erase the memory bar with an eraser, and check the memory of the gold finger whether there are traces of burning. Change memory slot.2, check the capacitor and a resistor board above, see whether there is a capacitance bulge, whether there is a smell on the motherboard, and clean up the dust on the motherboard.3, remove the CPU fan, electricity power, use hand to test whether CPU has no temperature change, CPU is not working, or bad motherboard, or not plugged in CPU, replug CPU.4, power problems, although the power supply, but the motherboard can not work properly, change the power to try.5. Show that the light is on, the keyboard light is on, the screen doesn't show, wipe the video card finger with an eraser, and check the capacitance on the video card whether it is bulging or not.6, to minimize the test, leaving only the power supply, CPU, motherboard, memory, video card, keyboard, display, put all the rest on the motherboard line are pulled out, with screwdriver short switch pin, if normal, then the rest of a piece of hardware, adding to identify the reasons for the problem.Tip: all operation should turn off the power supply, if the computer hardware is unfamiliar, it is recommended to find professional maintenance personnel to deal with.
