4. Why does the screen go black when the computer starts?

The reasons why the computer starts with a black screen may be due to the following reasons:

1. Heat dissipation problem

After the computer is turned on, it enters the system normally. After running for a period of time, the screen suddenly goes black. This situation is most likely caused by heat dissipation. It is normal. The temperature is 30-50 degrees. Under normal circumstances, any component exceeding 50 degrees will cause motherboard protection, so the computer will automatically shut down and restart. The solution is also very simple, add thermal paste or replace the radiator.

2. Graphics card or monitor problems

These two devices account for a large proportion of black screen failures when the computer starts up. Usually, the replacement method is used to use another monitor. If it is used normally, it means that the original monitor is broken. If the screen is still black after changing to another monitor, consider the host problem. Usually, it is easy to think of a graphics card problem. You can also replace the graphics card. If the display is normal, it means that the graphics card is faulty.

十、苹果电脑启动黑屏怎么办？

苹果电脑启动黑屏处理方法如下：

1．内存问题内存是计算机中最重要的部件之一。系统在加电自检过程中，能够检测出内存和其他关键硬件是否存在和能否正常工作。如果有问题或不能正常工作，系统就会用喇叭报警。喇叭的声音不同，表示不同的故障。内存有故障，喇叭发出的声音是"嘀嘀"。一台品牌机，开机后，喇叭发出"嘀嘀"声，显示器黑屏。很明显，是内存有问题。打开机箱，拔下内存，仔细察看，内存没有什么问题。将内存条换根插槽插上后，一切正常。

2．显卡不能正常工作如果显卡不能正常工作，计算机也会黑屏。但这时系统不会用小喇叭报警。一台电脑使用一年来，一直正常工作，但最近以来，电脑出现黑屏故障。开机后，系统自检正常，小喇叭不报警。但屏幕上显示"NoSignals"。据此，初步判断是显卡有问题。将显卡卸下后，发现显卡上粘满了灰尘，先用刷子把显卡刷干净，再用橡皮把"金手指"打磨一遍。然后插上显卡，开机，正常进入系统。这种问题，一般是由于时间长了，显卡的"金手指"部份因氧化而与插槽接触不良引起的。它的特征是系统自检正常，小喇叭不报警，显示器黑屏（比较老的显示器）或显示"NoSig－nals"（比较新的显示器）。处理这种故障的方法是检查显卡是否接触不良或插槽内是否有异物影响接触。

3．主板BIOS故障一台组装机，开机后黑屏，但喇叭不报警。通过检查，发现显卡没问题。由于是组装的电脑，于是怀疑是电源功率不够，把硬盘、光驱、声卡拔下，用最小系统法也不见效。将显卡、声卡换到别的机器上，又一切正常。这时，主板上的小电池吸引了我的目光，是不是它的问题呢？于是，将电池卸下后开机，系统显示正常，要求进行BIOS设置（主板放电法）。重新设定后，顺利进入WIN98。如果你也遇到类似问题，也可以试一试主板放电法，说不定问题就在这儿。
