Everything glows, spins, but there is no signal on the monitor?

Question

Iron

Hello everybody. The question is as follows. I kicked him while watching the video. It fell on its side, as a result of which it hung (I note that the image on the monitor remained until the reboot, which excludes damage to the cable or connector). I pressed the reset button on the system unit and it did not turn on anymore. Visually the system is working. The coolers are spinning, the backlight is on, but there is no image from either the integrated graphics or the discrete one (no signal). The speaker is silent, although it used to squeak at startup. I take out the RAM - the speaker beeps, with operational silence. Please tell me what to replace)

Answer 1

Sergey , is there no power or picture on the monitor? If there is power, replace the power cable. If the picture is try to borrow someone's monitor and check the picture. If there is no picture on the borrowed monitor, then the problem is most likely in the cable between the video card and the monitor. In this case, try replacing the display connection cable. If everything is in order with the wire, then the problem with a 99% probability is in the connector of the video card into which the cable is inserted, when it was dropped it pulled sharply and one of the contacts broke.

Answer 2

I had about the same thing, a discrete graphics dump happened, then I pulled out a video card and a percent, then I put everything in spinning, only the HDD lights and the work light on the front panel stopped flashing, I couldn’t figure out what was wrong.
