I start my PC up, all the lights light up, the fan starts cooling, and then... nothing. The monitor shows no picture, it doesn't show "no signal", it shows a completely black screen. Keyboard numlock capslock scrolllock are not changing if I press buttons, all of them are dark. It's as if my computer is in limbo. However, after a few tedious restarts, waiting in-between, pressing restart, pressing shut down and then power up, manually disconnecting the power cord, resetting bios by unplugging the battery, it works... for a few minutes, or even seconds. Again, the lights light up, the fan starts cooling, monitor gets a picture, keyboard reacts to everything I do, and then... nothing, again. If I'm fast enough I can sometimes boot up into windows 7 that it has on it's 2012~ish ssd, but it just blue screen's and again, goes into limbo. I cannot provide specifications of the system for it is not mine, and I would have to boot up windows and into device manager to find out, which I can't do. Please, help.
