1. Find the graphics card control panel and open it. The specific location can be seen in the control panel. You can also right-click directly on the graphics card's control panel "NVIDIA Control Panel"
2. Then find "System Information" in the lower left corner and click to enter the meeting A window pops up. In this way, you can see the graphics card information
This situation may be because the computer cannot detect a certain hardware during self-test or is stuck in detecting a certain hardware.
1. Keyboard and mouse. The power-on self-test will detect the mouse and keyboard. If there is a problem, it will cause it to get stuck in the self-test interface. The solution is to unplug the keyboard and mouse and check whether it passes the self-test. If it passes the self-test, replace the mouse and keyboard.
2. Hard drive and optical drive, most likely hard drive and optical drive. For desktop computers, you need to open the case and unplug the power cord of the hard drive and optical drive to see if it passes the self-test. If it passes, further rule out the problem of the hard drive or the data cable.
3. If none of the above is true, then the most likely problem is that there is a problem with the motherboard bios and it needs to be returned to the factory for repair.
1. Right-click "My Computer", "Manage", and "Device Manager".
2. Enter "IDE ATA or ATAPI Controller", right-click "Primary IDE Channel" and "Secondary IDE Channel".
3. Go to "Properties", "Advanced Settings" and set "Automatic Detection" to "OK".
4. After the setting is completed, restart the computer system and the hard disk self-test will be performed.
Skip method:
1. First enter the system desktop normally, find the "This PC" icon, and double-click it.
2. After turning on the computer, find the partition you want to self-test, right-click the mouse and select Properties.
3. A dialog box will pop up, and then switch to the tool category in the tab. 5. Then click "Scan Drive" in the pop-up settings panel and confirm to check. 6. Wait for the system tool to check the disk, then restart the computer. There will be no more automatic checks
After the computer starts, it directly enters the system interface without performing a self-test. If there is a problem with the computer software or hardware, or it did not shut down properly last time, the problem cannot be found, so the power-on self-test is crucial to detect the computer. .
Then I will teach you a simple method to restore the disabled computer power-on self-test function.
Click "Start" and "Run", enter cmd and press Enter. Enter chkntf /d to restore the computer's power-on self-test function.
1. First enter the system desktop normally, find the "This PC" icon, and double-click it.
2. After turning on the computer, find the partition you want to self-test, right-click the mouse and select Properties.
3. A dialog box will pop up, and then switch to the tool category in the tab.
4. Click "Check" to check for disk drive errors.
5. Then click "Scan Drive" in the pop-up settings panel and confirm to check.
6. Wait for the system tool to check the disk, then restart the computer. There will be no more automatic checks.
Solution:
1: Reinstall the system, or use GHOST to restore the system.
2: Use the PE system under DOS to repair bad sectors.
3: Press F8 to enter safe mode, right-click on My Computer, Properties, Advanced, Startup and Recovery, and when the recovery time is displayed, set the time to 10 seconds and check the box. After restarting, press ESC to skip the self-test. Question: When this happens, 90% of cases are caused by bad sectors on the hard disk. If the system is damaged, it will prompt that a file is missing, and it will not fail the self-check. If the self-check fails, it is basically because the hard disk has bad sectors and the system cannot read a certain file. causing jamming. You will understand by looking at the hard disk indicator light. In the area where the self-test cannot pass, check whether the indicator light is always on. If it is always on, it means the hard disk has bad sectors. If it is not on and the self-test cannot pass, there may be an error in the system file. Solution: You can use the XP installation disk downloaded from the Internet and try to use the system boot repair. To know if there are bad sectors, you can download a software called Hard Disk Sentinel. As soon as you open it, you will know whether the hard drive has bad sectors.
bios self-test repair
The system will start the bios code check after completing the self-test of the graphics card. The bios version number and motherboard model will usually be displayed on the monitor.
The L2 or L1 cache of the CPU is not completely damaged or other circuits of the CPU are aging
When the host completes the initialization of the graphics card, it will next start to detect the CPU self-test. When L1 or L2 of the CPU fails, it will be stuck at "check nvram..." for a long time. When this fault occurs, some machines can still enter cmos settings. We can manually turn off L1 and L2 of the CPU, and then try to observe whether the machine can pass the self-test. If possible, the CPU can basically be used at reduced speed. If not, you can only solve the problem by replacing the CPU.
Most of the time when the CPU is partially damaged, the system will report a BIOS error (similar to damage caused by the CIH virus), L1 or L2 error, cannot pass the self-test, can only enter safe mode, and automatically restart during the startup process.
1. Optimize the system
1. Reduce unnecessary startup items to reduce the load on the computer. Many software "like" to start when the system starts. Disabling startup items is one of the cost-effective and very effective ways to improve boot speed.
Nowadays Windows can be operated directly in the task manager. Other versions of Windows operating systems manage operations in the msconfig startup item. If you can't understand it, it is recommended to use third-party optimization software for optimization.
2. Disable unnecessary services. There are some services that we may never use. Disabling some services will also reduce the load on the computer.
Right-click on Computer→Manage→Services and set unnecessary services to disabled. If you can’t understand it, it is recommended to use third-party optimization software for optimization.
3. Clean up junk files reasonably.
Some optimization software frequently prompts how many junk files there are. In fact, frequent cleaning of garbage may make the computer boot slower, because some files are not junk files, but files pre-read by the computer. These files will speed up the computer startup to a certain extent.
Some residual registry entries have a great impact on boot speed, and some computer management software are difficult to remove. If you need to clear it manually, press winkey+r, enter regedit in the run window and press Enter. Open the registry and search and delete it through the keywords of the software name. It should be noted that there are certain risks in deleting the registry. The principle is not to delete if you are not sure.
2. Check for viruses
1. If the computer is infected with a malicious program, the computer will become extremely slow whether it is turned on or running normally. Therefore, the infected computer will be qualitatively improved after killing the virus.
There are generally three methods of anti-virus: ① regular virus checking, ② safe mode anti-virus, ③ PE system anti-virus.
2. For viruses that cannot be killed, you can reinstall the system.
3. Choose the operating system correctly
1. For computers with low configuration and old hardware, it is recommended to use the XP system.
2. If the configuration meets the requirements, it is recommended to use Windows 7 or 10. Microsoft has made special optimizations for the boot speed of Windows 10. With UEFI, even a mechanical hard drive can control the boot speed within 15 seconds.
If the memory is larger than 4G, from the perspective of making full use of resources, it is recommended to choose a 64-bit operating system.
4. Upgrade hardware
1. ソリッド ステート ドライブを交換し、システムをソリッド ステート ドライブにインストールします。ソリッド ステート ドライブの読み取りおよび書き込み速度は機械式ハード ドライブの数倍であるため、ソリッド ステート ドライブを交換すると、コンピューターの起動速度が大幅に向上します。
3. メモリモジュールを追加します。メモリはコンピュータのキャッシュです。メモリが不足している場合は、メモリ スティックを追加すると起動時間が短縮されます（ただし、ノートパソコンのシリーズやモデルによって異なります。現在市場にある多くのノートパソコンは、薄さと軽さを追求しており、メモリは 1 つしか搭載されていません）。メモリ モジュールを追加します)
5. ソフトウェアおよびハードウェアのトラブルシューティング
1. コンピューターのソフトウェアまたはハードウェアの障害は、コンピューターの起動パフォーマンスに重大な影響を与える可能性があります。コンピューターの障害のトラブルシューティングには、通常、最初にソフトな方法、次にハードな方法が必要です。
ソフトウェア関連の理由を完全に排除するには、システムを再インストールすることを選択できます。ソフトウェアが原因で起動が遅くなる主な理由は次のとおりです。
① 異常なシャットダウンやその他の理由により、システムまたは他のアプリケーション ソフトウェアのファイルが破損する場合、通常、関連する情報は、実行中にシステム ログから見つかります。操作を開始します。
②ドライバーやその他のソフトウェア自体にバグがあるか、システムと互換性がない場合、通常、関連する情報はシステムログから見つけることができます。
③ディスクエラースキャンまたはシステムアップデートは、次回から表示されないよう、完了するまでお待ちください。
2. 元のシステムで再インストールした後も起動が遅い問題が解決しない場合は、おそらくハードウェア障害が原因であると考えられます。起動が遅い原因となるハードウェア障害には次のようなものがあります:
①不良セクタなどのハードドライブの障害。具体的な症状には、セルフチェックの遅さ (BISO はマザーボードのブランド情報を表示した後にハードウェアの動作ステータスをセルフチェックします)、認識の失敗、またはハードディスクのライトが常に点灯しているが点滅しないなどがあります。コンピューターの起動が非常に遅い、または起動できません。失敗する可能性が高いです。
②キーボードやマウスなどの入出力デバイスの故障が原因。主な症状には、セルフテストの遅さ、起動の遅さ、入出力デバイスの障害などがあります。失敗する可能性が高いです。
③ネットワークカード、ネットワークケーブル、ネットワークが異常または破損しています。主な症状は、ネットワーク ケーブルが抜かれているときは正常に動作しますが、ネットワーク ケーブルが接続されているときは起動が非常に遅くなるということです。失敗する可能性が高いです。
④メモリ、グラフィックスカード、CPU、マザーボードなどのその他のハードウェアの故障。失敗する確率は低いです。
上記は、コンピューターの起動が遅い理由に関するチュートリアルです。一部の操作には特定のリスクが伴います。必ずデータをバックアップするか、関連情報を確認してください。それが役に立てば幸い。
