Such a configuration boots up slowly and the screen flickers

It's good to just buy something you still don't move, and go directly to the merchant who sells your computer to ask for a replacement of accessories Now**7 days to replace it, and the goods in the warranty period are not repaired, depending on the situation you wrote, it should be a problem with the graphics card or the monitor, this must be required to be replaced with a new one, this is a quality problem, in other words, this is also normal, when I used to do it in a computer company, I ran to the warehouse to get the goods, and after loading it, it was a little bit not lit or something like that As for the boot problem, it may be that your current system is running more things, and the system has not been optimized, and of course, there are some hardware compatibility problems, and it's okay for 48 seconds.

Just bought something or do not move directly to the computer business to sell you a request for replacement accessories**7 days to replace the goods with a warranty period messed around, see what you wrote should not be rework is another new quality problem, say this sentence of the graphics card or monitor must also belong to the normal computer company before is run dry, installed a little warehouse to get the same thing as the goods, the sooner the problem is solved, the better, after all, the problem of profiteers fame and fortune may be more things running on your system, Like some hardware compatibility issues, it didn't do optimization for 48 seconds for it.

It seems that your computer is just equipped, you can go and change it! Don't do it yourself, if you break it, you can't change it.

The speed of booting is actually just a matter of the mind. If you're going to boot fast. I can make your boot speed 18 seconds. My machine is much lower than yours and never turns on for more than 27 seconds.

The common causes of screen failures such as screen flickering, screen shaking, etc. are:

1. The quality of the screen itself, the screen is aging or inferior products.

2. Poor or damaged contact of the screen line.

3. The power supply of the motherboard screen is abnormal or the seller is the blurred screen fault caused by the virtual soldering of the BGA seal and remaining chips of the graphics card.

4. It is recommended to send it for repair and testing, and send it to customer service for free maintenance during the warranty period, except for man-made damage.

I'll give you a few ways to try, after all, I didn't see your computer, and it's not very easy to judge.

1. Right-click on the desktop -- Properties -- Desktop -- Customize the desktop --web -- Convert the "Current Home Page" and "http .) in the "Web Page" barRemove all the checks in front of all items ("http" is the address of the web page or ** added from the Internet, generally not needed, you can delete all of them), and remove the checkmark in front of the "lock desktop item" below, and click OK.

2. Enter " in "Run" to open Group Policy; In "User Configuration Administrative Templates Desktop Active Desktop", click Enable Active Desktop, then click "Properties" to select "Disabled", click "Disable Active Desktop" "Properties" to select "Enabled"; Are you sure. ps:xian86913

3. Right-click "My Computer" Properties Advanced "Performance" bar and click "Settings" Visual effects Check "Use shadows for icon labels on the desktop" and click "Apply" to confirm. ps:xian86913

4. Right-click the desktop -- arrange the icons -- remove the tick before locking the web project on the desktop: ps:xian86913

If none of the above can be solved, it is estimated that there is a problem with the hardware, which is best solved by a repair station or a qualified computer repair company.

Hope it can help you, [good luck].

A black screen is a common phenomenon, especially on older computers or builds. There are many reasons for the failure of a computer black screen, such as a damaged monitor, a damaged motherboard, a damaged graphics card, a poor contact of the graphics card, a damaged power supply, a damaged CPU, etc.

1) The monitor is powered off, or the monitor data cable is in poor contact. In addition, the computer has been used for a long time, and the power cord of the monitor is easy to oxidize and break;

2) There is no power supply to the motherboard;

3) Poor contact or damage to the graphics card;

4) Poor CPU contact;

5) Poor contact of memory modules;

6) Machine infection.

CIH virus, BIOS

is destructively refreshed;

7) Check the plugging and unplugging, if necessary, you can use a rubber to remove the oxide film on the gold finger;

8) If the floppy drive has a floppy disk, many times it will cause the computer to start or restart, and the computer will have a black screen and cannot enter the system. To avoid such situations, it is also possible to cancel the floppy disk boot item in the BIOS.

For the treatment of the black screen of the computer, the method of eliminating and replacing is basically adopted, and the principle should be based on replacing and eliminating the most suspicious parts first. For ordinary computer users, professional knowledge is insufficient, you can follow the following steps to analyze the cause of the failure, so that you can do it yourself.

Start by checking that the contact is good. Check whether the contact between the graphics card and the monitor is good, and whether the contact between the graphics card and the motherboard IO slot is good, and if necessary, remove it and reinstall it again to ensure that it is installed in place and in good contact.

If there is no problem with contact, it is best to try a different monitor to make sure that the monitor is fine.

If there is no problem with the monitor, check whether the CPU fan is running, if it is running, use a multimeter to measure whether the voltage output is normal to 12V, 15V, if not, you can change the power supply to give it a try.

If the black screen still appears, take out the components installed in the computer, leaving only the CPU, graphics card, and memory sticks, and the cause of the fault can be limited to the CPU, motherboard, and memory. Generally, if there is a fault in the memory, there should be an alarm sound. If the memory fault is ruled out, only the CPU and the motherboard are left.

Change to a normal CPU (should be compatible with the tested computer), boot the computer and re-test, if the black screen still appears, you can only change to a motherboard, and the problem should also appear on the motherboard.

A black screen may indicate a serious problem with your computer, and you may wish to eliminate it as described above when the black screen occurs. In the process of treatment, the method of exclusion and substitution should be flexibly applied, and the phenomenon that occurs in a timely manner should be excluded.
