Black screen when starting the computer. What to do?

Question

Iron

Yesterday I got a black screen while working. At first he referred to vidyuhi, he thought he was dead, but no. Bios is loaded, even one short beep. After loading the bios, a black screen flies out and everything is tight. Trying to start the boot menu (launches) a second passes and again a black screen. I pulled out the frame and vidyuhu with an eraser, blew through the connectors, I thought dust got in (to no avail), removed the battery from the uterus, dumped it, it didn’t help. Please help.

Answer 1

Is the monitor dead?
You can turn on the computer, wait until the monitor gives a black screen, turn off the monitor, wait 2 minutes and turn the monitor back on.
If a picture appears on the screen and then disappears, the monitor is broken.

Answer 2

There may be a problem with the drive on which the OS is installed. If possible, try running some linux distribution from a USB flash drive / disk, if it starts, then the problem will be either with the OS itself or with the drive on which it is installed.
