Miracles happen to him, namely: when turned on, he does not pass the fast, i.e. the fan just spins and that's it, it can be fixed by resetting the BIOS with a jumper or removing the battery for 30 seconds. As a result, after that the computer may be overloaded or turned off, but it will start normally. In the evening, the employee turns it off and goes home, in the morning the same song, it turns on but the post does not go through. I changed the bios, changed the battery, tried to turn off the devices one by one to find out what was preventing me from going through the post, but even then miracles. I turned off the usual railway one by one - nothing, turned off the solid-state one - the computer started up. I connected the solid state again - it turned on, I connected the usual one - it turned on. What could it be???

Answer 1

Anything can be. For example, lousy power or swollen capacitors. If POST fails, try a POST card.

Answer 2

Wipe the RAM contact track with a regular eraser, if it doesn't help, run Memtest.

Answer 3

Power supply or cant in bios

Answer 4

Blow it out to try, maybe something is shorting somewhere
