B250 motherboard mining is not on
now the mining instry is basically collapsing, and it's all the plate takers
sooner or later
if you have to mine, remember to install the original system + driver 7 and update the driver, so that mining can be stable enough.
2. If the power light is on after the switching power supply is replaced, but it still can't be started, press the num lock key, and the num lock light won't be on. In this case, the motherboard can't start normally. Please shut down, remove the memory, clean the memory golden finger, and then re insert it
3, then check the graphics card, clean the golden finger of the graphics card, re insert the motherboard, and then try to power on. If the keyboard light is on after power on, press num lock key, the corresponding light will also be on, which is basically the problem of the graphics card
4. If the screen is still black, but the display is normal after changing to another monitor, the monitor is damaged and needs to be repaired. If it is the same after replacing the monitor, try to replace the graphics card. If it is normal after replacing the graphics card, the graphics card is damaged and needs to be repaired or replaced
5. If the system just fails to boot, makes an error or has a blue screen, it can be solved by re installing the original system.
Problem analysis:
when the computer is powered on, the main board is powered on, and the display is powered on (the power indicator is on), but there is no signal or "no sighal" is displayed on the screen. Generally, the memory mole is loose or oxidized, resulting in poor contact, or the data line of the display is in poor contact, or the memory, graphics card, display or data line is damaged
processing suggestions:
1. If the display is powered on but no signal is displayed, turn off the power supply (if short pressing the power switch is invalid, long pressing the switch until the power indicator is off or directly unplug the power cord) power off the boot box, plug in the memory mole again, and wipe the golden finger with a rubber in one direction (thumb and fingernail back scraping is also OK), If possible, it can also be installed in different memory slots, and then it can be turned on (before operation, it is necessary to release its own static electricity by touching the wall with both hands or wear anti-static gloves). If you don't know how to operate, it's a little simpler: just slap or kick the chassis once or twice (Note: the right and left side of the chassis are in the center of the shell without interface at the back; Attention: don't push too hard, of course not powerless). The above operation may need to be repeated. If it is invalid, the memory mole needs to be replaced. If there are more than two memory moles, you need to test them one by one
If the above operation is invalid, power off the boot box, plug in the graphics card again, and plug in the data cable between the display and the graphics card tightly. If it is still invalid, consider the data line or graphics card damage, then replace the new data line or graphics card If the monitor is not powered on (the indicator light is not on), first check whether the power switch is on, then check the back of the monitor, plug the plug of the power cord connecting the monitor upward (replace the power cord if possible), and check whether the other end of the power cord is powered on to the socket4. If the display can be displayed when the host computer is connected to other displays or the display of the host computer is connected to other normal hosts, it means that the display is damaged and needs professional maintenance
1. Plug the power cord tightly, check the plug on the plug board, and make sure that the plug board is powered on
2. Make sure that the cable from the host power supply to the board is good, then remove the 24P plug from the power supply to the main board, and short the green and any black wires. If the power fan turns, it means that the power supply is OK. If the power fan doesn't turn, it means that the power supply is broken. Replace it with a new power supply
3. After confirming that there is no problem in the above two steps, unplug the switch cable connecting the main board and the front panel of the chassis, and use a screw driver to short circuit the two pins of the switch. If the fan turns, it means that the main board is OK. If the fan doesn't turn, it means that it is mostly the main board problem. Contact professional maintenance personnel to deal with it
4. Short circuit the pin of the main board, and press the switch button on the front panel, but there is no response. It means that the switch button is broken or stuck. Replace it with a new switch button, or get the stuck button up.
replace the independent display and restart the computer system, Just re install the driver.
1. Press Win + X on the desktop and click the power option
2. Click "select power button function" in the left window
3. Select "change the currently unavailable settings"
4. Find to enable quick start and remove the previous check. Save the changes
5, and then try shutting down
note: if normal, you can check the quick start again according to the above method.
turn off the keyboard and mouse power on function in BIOS and turn on the power management setup page in the main menu of BIOS, Find S3 KB wake up function or similar options (such as resume on KBC, resume on PS / 2 mouse, etc.), set it to disable, turn off the + 5VSB power supply of the main board to the keyboard and mouse, and the PS / 2 photoelectric mouse will not light up naturally after it is turned off
there is a jumper on the motherboard. Just change the jumper to another location. The location is probably near the mouse interface. Look for it
