My PC is performing strangely the past 2 days. If my pc starts up with a normal boot, restart etc. everything is fine.
On the other hand if it is "fast-booting", the windows boot logo is displayed for a couple of seconds and then it powers off completely. After that it performs a normal boot. Which takes surprisingly long time for a system with an ssd. (Previous installation of windows 8.1 lead to 5 seconds boot time, now it is about 20).
Fast boot is enabled both in UEFI and Windows (10). Power plan favors performance. If pc specs are required I will edit my question.
I cannot trace the problem to its source.
