Suddenly PC goes black screen with "No Signal" and shutdown is impossible.
\nWhen we build a computer, sometimes it goes black screen.
\nIf we cut power and restart it, the OS starts.
\nBut after a while, it gets black screen again.
\nToday I will share about reason of this issue.<\/p>\n
<\/p>\n
<\/br><\/p>\n
We can estimate these causes for black screen issue.<\/p>\n
How can we figure out root cause from these options ?<\/p>\n
<\/br><\/p>\n
If it is caused by display or cable, it is easy.
\nYou can check by changing display or cable.
\nThen if issue is cleared, it is display or cable issue.<\/p>\n
<\/br><\/p>\n
Sometimes GPU has some trouble.
\nAnd after a while, it causes circuit break and screen issue.<\/p>\n
In order to check it, we can also reboot with other GPU.
\nIf there are no issue with other GPU, root cause is GPU.
\nYou can replace it.<\/p>\n
Another check method is using music.
\nWhen we start our computer, we start music.
\nThen in case of black screen, if music continues, it means computer is alive except graphics.
\nSo its root cause is GPU.<\/p>\n
<\/br><\/p>\n
\nOne simple way to determine if this is what\u2019s happening is to play some audio on your computer. Load up a longish mp3 play list or streaming audio station and let it play. If the monitor suddenly goes black, but the music continues to play, you know that the computer is still running.

CPU<\/h3>\n
Overheated CPU may cause black screen.
\nLike the movie below, if you use IntelBurnTest<\/a> and black screen happens, it means root cause is CPU cooling issue.
\nYou can put thermal grease between CPU and CPU cooler.
\nOr you can buy another CPU cooler.<\/p>\n
