For novices who are building a computer for the first time, boot settings are a headache. How to correctly configure the BIOS, install the operating system, connect peripherals, etc. all require certain skills. PHP editor Baicao will provide you with a detailed guide to solve the problem of startup settings step by step. Welcome to read the details and let your new computer start up easily!
After assembling the computer by yourself, don’t rush to turn it on first. Check whether the hardware is plugged in firmly, and then plug it in and try to turn it on. Since the newly installed computer does not have a system, after turning it on, first go to the bios to check the motherboard settings and install it. Before the win system, if you install the system from a USB flash drive, first set the first boot item of the bios to USB boot. After restarting, you can insert the USB flash drive to install the system.
Answer: Suggestions for handling a newly assembled computer that has a fan running at high speed but does not turn on:
1. When the monitor is powered on and the signal is displayed, shut down (short press the power button to turn it off, then press it until the power indicator light goes out or unplug it directly) Disconnect the power cord) Power off the case, re-insert and unplug the memory module, and wipe the golden finger with an eraser in a direction (scratching the back of your thumb and fingernail). Reinstall the machine (before operation, touch the wall with both hands to release static electricity or wear anti-static gloves). Simple: slap or kick the chassis twice (note the position: there is no interface on the left and right sides of the chassis; pay attention: use too much force). If the operation needs to be repeated, the two memory modules need to be replaced one by one. Root test
The analysis and solutions to the reasons why a newly assembled computer cannot be turned on are as follows:
1. There are poor contact problems in various internal components of the machine, such as the most common memory contact problem.
2. There is poor contact between the host and the monitor.
Solution:
1. First, observe whether there is poor contact between the host signal line and the monitor. 2. Turn off the computer and open the case. There is a long strip of equipment on the motherboard, which is the memory. If you look at it, there are two buckles on both sides. If you open it, you can take out the memory and reinsert it (note that it must be inserted in place). ), and then boot up
When assembling a computer, the first step is to select the motherboard, CPU, and memory. harddisk. graphics card. chassis and power supply.
The second keyboard, mouse, monitor, camera and other peripherals.
The third part is assembled. Insert the cpu, hard drive, and graphics card. Power supply, etc. are connected as required. The keyboard, mouse, and monitor peripherals are connected to the corresponding interfaces.
The fourth step is to choose a windows system or a linux system when making a system disk. The fifth step is to install the system.
The sixth part starts.
There may be incompatibilities between systems or programs. Press F8 after booting until the advanced options appear, then let go. Select "Last Known Good Configuration" and press Enter to fix it. If it still doesn't work, press F8 to enter safe mode and restore. Download or reinstall the system.
Caused by excessive temperature of the CPU or other hardware, incompatibility or failure of the memory and graphics card. The hard disk has bad sectors. Please use the system's built-in functions or software to repair the disk, or format the hard disk, repartition the system, and reinstall the system. Power failures and voltage instability can also cause automatic restarts.
Driver incompatibility can also cause restarts. Motherboard component failure. Change the system's default automatic restart: right-click My Computer/Properties/Advanced/Startup and Recovery Settings/uncheck "Automatic Restart" in System Failure, then press OK and Apply to restart the computer. If the above methods are ineffective and you cannot find the problem yourself, it is recommended that you go for maintenance. Go to the device manager and check if there are any conflicts with various drivers. Are there any yellow ones? If it is possible that the device driver is incompatible with the system; then delete the drivers for the sound card, graphics card, network card and other devices, and then install the drivers one by one. Restart the computer after each device is installed to check which device it is. After the fault caused by the driver is detected, download the new version of the driver for the faulty device and then install it. Then clean the dust in the computer, clean the gold fingers of the memory, graphics card and other equipment, and reinstall the memory and other equipment.
1. If the monitor is powered on but shows no signal, shut it down (if a short press of the power switch does not work, press and hold the switch until the power indicator light goes out or unplug the power cord directly). Turn off the power, open the case, and re-insert and unplug the memory. strips, and wipe the gold finger with an eraser in one direction (scraping the back of your thumb nail will also work), and then turn on the phone after installation. If you don't know how to operate it, then it's simple: just kick the chassis (note the location: the center of the side of the left and right side of the chassis that has no interface at the back). If it's a laptop, you can't kick it, but other operations are the same.
2. If the above operation is ineffective, shut down the computer, open the case, re-insert and unplug the graphics card, and tighten the data cable between the monitor and the graphics card. If it still doesn't work, consider the graphics card is damaged and replace it with a new one.
3. If the monitor does not have power (the indicator light does not light up), look at the back of the monitor, plug the power cord plug connected to the monitor upwards, and check whether there is power from the other end of the power cord to the socket.
4. If the host can be displayed when connected to other monitors or the local monitor still cannot be displayed when connected to other normal hosts, it means that the monitor is damaged and needs repair
If there is no chassis: Find the double row of bare pins from the motherboard (usually including PWR_LED, RST, HDD_LED, PWR, etc., meaning: power indicator light, restart, hard disk indicator light, power supply) . Just short-circuit the two pins of the power supply (connect them with a conductor). If you are using a tractor card: you still need to turn on the host power supply
Assemble a desktop computer and reinstall the system:
1. Make a USB flash drive, then go to the relevant website to download the win system and save it to the USB boot disk, restart the computer and wait for the boot screen to appear and press Start Shortcut key, select u disk boot to enter the u boot main menu, select the "u boot WIN8PE standard version (new machine)" option, press the Enter key to confirm
2. Select the win image in the pe installation tool Place it in the c drive and click OK
3. At this time, click the "OK" button directly in the pop-up prompt window
4. Then the installation tool starts to work, we need to wait patiently for a few minutes
5. After completion, a pop-up prompt box will prompt whether to restart immediately. At this time, we can just click Restart Now.
6. At this time, you can remove the USB disk and restart the system to start the installation. We do not need to perform any operations, just wait for the installation to complete.
After the new computer is assembled, there is no signal on the monitor when it is turned on. You can check to see if it is due to the following reasons:
1. Is the power turned on? If the power is turned on, check to see if it is the power supply of the monitor. Not plugged in properly
2. Check whether the VGA or HDMI cable is plugged in properly. Some computers have two graphics cards, try changing the socket
3. Is the monitor switch turned on
If the above checks are done, there will generally be no problem.
In this case, there must be a problem with the motherboard or memory. It is recommended to ask someone to borrow a memory and try to boot it normally. If it still doesn't work properly, you can go directly to the merchant to replace the motherboard.
