The computer suddenly froze, the black screen went black, and the computer automatically restarted a

The main thing is that the CPU usage is too high.

It is recommended that you use a rabbit or an optimizer to clean the cache.

In addition, you can turn off the automatic scanning of the antivirus software at the time of the card.

Or change to an antivirus software that takes up a relatively small cache...

1. Open the case, remove the dust, check the heat dissipation of the CPU and graphics card, and oil the fan.

2. Antivirus. Unplug the network connection, turn off System Restore, and use the latest version of antivirus software to kill the virus in safe mode, and it is best to change to another antivirus software to kill again.

3. Use the optimization master or Super Rabbit or Huangshan Repair to repair and repair IE.

4. Clean up and defragment disks.

1. In the window of my computer, right-click the drive letter you want to clean up - "Properties" - "Clean Disk" - check the files you want to delete - OK - Yes.

2. Clear the temporary file, start-run-enter %temp%-OK.

3. Clean up the registry and junk files with Optimizer or Super Bunny.

4. Close some startup programs, start-run-msconfig---start, in addition to anti-virus software, input methods can be turned off in general.

5. Delete unused program software.

5. Upgrade the graphics card and network card driver.

6. Increase the physical memory, replace it with high-quality memory, and set up virtual memory reasonably.

1. To play games, the virtual memory can be set to be larger, the minimum value is set to 1-2 times of the physical memory, and the maximum value is set to 3-4 times of the physical memory. If you want to do more than 1GB, you can set it to automatic.

2. The method of setting virtual memory is: right-click on my computer - Properties - Advanced - Performance Settings - Advanced - Virtual memory change - Select the partition where the virtual memory (page file) is stored in the drive list - Custom size - Set the value in the "Initial Size" and "Maximum", then click the "Settings" button, and finally click the "OK" button to exit.

3. The partition where the virtual memory (page file) is stored must have enough space, the hard disk resources are insufficient, resulting in insufficient virtual memory, in a computer, it is enough to set up virtual memory in a partition, it is not necessary to set it in multiple partitions, it is best to set it in a disk other than the partition of the system.

7. Optimize your computer with Optimizer or Super Bunny.

2 reasons: 1) The temperature is too high, change the fan 2) The power supply is faulty, change the power supply.

It is impossible to judge, and computer failures are not one-to-one, one problem and one root system.

A black screen is generally caused by poor heat dissipation and overheating.

Poisoning. Graphics card issues.

Hardware. Poor contact.

Computer black screen is a problem that users often encounter in the use of computers, and black screen failures caused by computer host failures Black screen failures caused by computer host failures can be mainly divided into the following categories—

Faults caused by the host power supply.

Faults caused by the quality of the accessories.

Connections between accessories.

Black screen glitch caused by overclocking.

Black screen caused by other reasons.

The black screen failure caused by the failure of the monitor itself and the black screen failure caused by the failure of the display itself According to the author's usual experience, it is mainly caused by the following reasons.

The AC power supply is insufficient.

The power switch circuit is damaged.

Damage to the output circuit.

If the screen is black all the time, it should be the hardware topic;

1。Unplug the network card and give it a try.

2。Buckle the COMS battery and put it back on.

3。Plug and unplug the memory as if it were a discrete graphics card.

4。Check if the CPU fan is turning smoothly.

If the screen is black all the time, it should be the hardware topic;

1。Unplug the network card and give it a try.

2。Buckle the COMS battery and put it back on.

3。Plug and unplug the memory as if it were a discrete graphics card.

4。Check if the CPU fan is turning smoothly.

It should be a bad heat dissipation, open the chassis, clean up the CPU inside, the dust on the graphics card fan and the power supply, if it doesn't work, you have to replace the CPU fan with a little more power, there are a lot of problems recently, all of them were when the machine was configured before, the fan power was small, and the computer had been running for a long time, useless system garbage, more dust, running large online games, etc., the CPU occupied more, and the heat dissipation could not be dissipated quickly, resulting in the CPU temperature being too high, causing the computer to reflect slowly, crashing, etc.

If the graphics card or monitor is broken, will the system boot normally?

It is recommended to find a monitor to borrow and take a look, and if you can't see it, the graphics card is broken. Not a big deal.

It's basically not a hardware problem, redo the system eight I didn't see the computer, I'm really not sure.

There are several possibilities for this, 1. Your CPU or graphics card does not dissipate heat well, check the fan, if you don't clean it for too long, it will accumulate dust, just brush it.

2. There is no problem with the motherboard, this is more troublesome, go and collect a 2-hand board in the Shouxun Hall, 200+ is not expensive.

3. The graphics card driver is damaged and needs to be reinstalled. It is recommended that you go to the next driver wizard to update the latest graphics card driver.

The first is poor CPU heat dissipation, the second power supply, and the third graphics card, so the situation is poor depending on whether the CPU cooling fan is not good.

1 may be your computer's hard disk or optical drive damaged, 2 may be insufficient power supply, the current computer supports ACPI power saving management, the device will stop working if it does not read data for a period of time, and will wake them up again when needed. Trouble.

When the system reads data from the hard disk again, the hard disk is not awakened due to insufficient power or its own fault, at this time, the computer will be stuck and bent down, crash or restart.
