A black screen of death after a few minutes of entering the system

Could it be a graphics card issue.

Not being able to keep up with the software you're running causes it to freeze.

1. Graphics card issues.

2 Hard drive issues.

3. Reload the system.

Why does the computer screen go black after booting up, and how to solve it.

First the memory check the hard drive ! It's Lao Tzu!

CPU heat dissipation problem, open the case, brush the ash under the CPU fan, that is, on the heatsink, and remove the fan if possible.

There are several possibilities for this situation, first, check the condition of your graphics card fan, which is generally a problem of insufficient heat dissipation. (This is more likely).

Second, check your motherboard, whether there is a bulge of capacitors on the motherboard.

Third, check your hard drive and system.

Fourth, check your memory module, or replace the slot.

Machines 5 years ago were generally HY 128m and 256m memory. This memory is unstable. Prone to some minor problems. And it's been used for so long.

Solution: Try changing the memory. or if the CPU fan is normal.

Besides, if you install the XP system, the machine will be very slow.

It's likely to be a problem with your motherboard.,It's the same with my classmates before.,As long as you play it, the screen will go black.,But after a while, it's okay.,Later detection is that a chip on the motherboard is burned.,You can first see if there's a chip on your motherboard that has been burned.,If there is, take it to the secondary maintenance and replace it with a chip.,If not,Then it may be your graphics card.。 When your test equipment is insufficient, it is best to send it to the repair station for engineers to help you carefully inspect and solve the problem as soon as possible.

It may be a problem with the power supply! Can you write your configuration in full, let's take a look.

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. z

There are three possible reasons for this problem.

One: system problems. General system problems may lead to restart, crash or black screen, reinstall the system is no problem, you said one-click restore does not work, it may also be a problem with the hard disk, or you can reinstall the system in the entire partition.

2: The CPU temperature is high, detect whether your CPU fan will rotate, or whether the silicone is dry, or the CPU fan can't touch the CPU, etc.

Three: motherboard problem, this problem is best to take to the maintenance department for testing, generally more is the north and south bridge problem, if it is the north and south bridge problem, it is recommended that you change a board, repair is not necessary, expensive and often out of the situation.

The lower probability is that the memory, power supply, graphics card, etc., but generally not these problems, but there are still possibilities.

CPU take a look, it's more likely! Or switch to a different CPU! I think it's because the CPU temperature is high! You have to be more detailed, otherwise it's hard to say

1.Hard drive issues.

2, can't get into a word, a, the system is not done, do PE again, or press, get the hard disk failed or prompted your hard disk problem, unplug the hard disk if you can go in, hard disk problem.

The failure caused by such a problem is caused by the following reasons: 1. The graphics card is caused by poor contact with the motherboard, reseat the graphics card, 2. The capacitance of the graphics card is damaged, then you can only replace the graphics card, 3. The memory is in poor contact, and you have plugged it in, so you can rule out 4 The CPU is caused by poor heat dissipation, that is, the CPU temperature is too high, 5 CPU is physically damaged, and 6 The hard disk has bad sectors. You can replace the hardware to rule them out one by one.

It is estimated that there is a problem with the CPU, it may be burned out, and it is said that you want to buy a CPU when you get a second-hand computer, try it again, and don't buy it if there is still a problem with it, and then check other accessories.

Most of them are caused by poor compatibility, and they have to be debugged in a special store.

If the machine is not connected to the Internet or has anti-virus software installed, it is a memory failure, and it can be solved by replacing the memory.

It may be that a system file cannot be found, and it is recommended to redo the system.

Is the memory incompatible? Or is it caused by bad sectors in your hard drive?
