Momentary shutdown of the monitor for 1-2 seconds. What could be the problem?

Question

Iron

Good day. Actually, the problem is that periodically, regardless of the tasks performed on the PC, the monitor goes out for 1-2 seconds, while the on / off button of the monitor remains lit in blue and does not change color to yellow (which means that the monitor is on). In this case, a click occurs in the columns. It was also noticed that the moments of such outages do not depend on time. It may not show any signs for 2-3 days, and then blink several times in a couple of hours. Still very often this happens when I turn the speakers on and off from the network, in about 2 out of 5 cases the monitor blinks under these circumstances. The system unit was completely replaced with a new one, which did not solve the problem. Only the monitor, keyboard and speakers remained from the old one. The audio wire was also replaced with speakers from the PC. Doesn't respond to vibration or tapping. The speakers emit a little light if you listen in complete silence, and sometimes, very rarely, they make rustling sounds that do not affect the operation of the monitor, which then disappear by themselves after a while. In general, the most important thing that I would like to know is whether I will ruin the system with such jokes? Maybe there is something to close or something else I do not know. And if there are experts in such matters, then I would like to know at least approximately what to expect, everything under replacement or one thing? maybe it can be fixed?

The video card switches the monitor to a mode that is not supported by it. I did it with a program from ASUS. There may also be a program using DirectX with an error. Look for the bastard.

Монитор в ремонт отправляй.

Answer 5

У меня так происходит, когда старый холодильник включается) причем монитор может пару дней не выключаться, а на следующий день отрубаться при каждом втором запуске холодильника.
И в том, что в моем случае виноват холодильник, я уверен.
