I downloaded the tool Speccy and it says my CPU tempurature is over 90 degrees C.
I powered off the computer for the night but in the morning it is still running hot.
What causes this and how to do prevent it?

Old dried out thermal paste, dust, clogged fans, bad CPU cooler mount etc.

Adding to this, on the software side - it could be corrupted applications on startup/background, drivers or even bios. Also, once had an old laptop which overheated when fast startup was on.

You mean, you shut down from the OS and leave the power switch on, and it was running hot before you even boot the system back on!?

Software cannot make a system overheat. It can make it run hot but not hotter than a stress test.

Thermal paste & Cooling - These are pretty much the only things that keep your CPU cool. Since nobody has mentioned this, If you have recently got a new PC with an AIO cooler, there is usually a plastic sticker on the heat sink plate that can be forgotten to be removed, thus leading to very high/abnormal temperatures. You will have to disassemble your CPU/Cooler to check for said possible issues, do have a look at this as well if applicable in your case.
