Computer hangs after first boot?

I gave my dad a new notebook from Dell. The hard drive (SSD) I have specially purchased because only one HDD was inside. Windows 10 installed on it, a few programs on it. Now I want to start the computer, the desktop loads completely and then hangs up immediately. If I press the power button for a long time, the computer will shut down. If you drive it up then you can use it without any problems, nothing hangs up. Have ever one of the two memory modules already expanded and it behaves unchanged. Drivers are up to date. If someone has an idea approach, please report.

Seems to be a software bug, Windows 10 would reinstall

You would have to look at the error record. Does the fan turn up when it hangs up? And then you hear a roar from the speakers?

I have a similar problem with mine. I guess the error is due to a lack of power to the CPU.

Presumably wants a process / service from the startup menu make any connection (call home…) and does not do it. Check all the startups (for example with CCleaner).

Good suggestion - but I would do in safe mode when the PC hangs up in normal mode quickly.

No, no loud murmur and no upturned fans.

Had already disabled all times. That's not it

Already happened, no noticeable change
