Hello Nico_nicz

Since you didn't mention which operating system you are using and the default OS that the laptop has is Windows 8, I will continue assuming the same.

Assuming that you can see the Compaq logo when the laptop powers on but freezes during Windows booting process, you can try starting Windows 8 in Safe Mode. The process of starting Windows 8 in Safe Mode is identical to the one used for Windows 10 and you can see the step-by-step instructions here.

After booting in Safe Mode, try restarting Windows normally. Most of the times this resolves the issue. If it doesn't, restore Windows 8 to an earlier restore point from within the Safe Mode itself. Here you can find the step-by-step instructions to restore Windows 8 to a restore point.

Let me know if this works. Good Luck!!
