Hi Squeeeze,

Running the PSA hardware diagnostics will help us to identify if there is any problem with the hardware.

Please release flea power and run the PSA hardware diagnostics.

Switch off the system; remove the battery, ac adapter and the power cable. Press and hold down the power button for thirty seconds to drain any excess flea power and then try running the test. 

You can run the PSA hardware diagnostics in your computer to check the hardware is working as designed. Follow the steps below to run the PSA diagnostics.

Turn the computer off >restart the computer 

At the Dell logo screen, start tapping the F12 key a few times until you see the ‘One Time Boot Menu’ appear.

At the one time boot menu, press the down arrow key to highlight ‘Diagnostic’, and then press Enter to begin the PSA diagnostics.

 If the test fails, please make a note of any error codes listed. You can also refer to the link below.

all cable are connected properly, so the problem is maybe the used CPU that i buy? but why did it boot sometimes to windows loading screen and freeze and why sometimes did it no boot at all?
