Why does the PC go to sleep and shut down for a long time?

Question

Computers

I have a computer
Asus m4n68t le v2
Amd athlon II X3 450
4 gigabytes of RAM
Rx 474
Ssd adata su 800
Hdd samsung for 160 gigs ((I don’t remember the full name) in the Crystal disk info is yellow so I’m sinning on it)
Now to the problem itself when I turn off the PC or enter sleep mode, the cooler works for a long time (1-2 minutes), that is, the monitor has already gone out, (if this is the sleep mode, the LED on the case starts flashing, which means that it is already in sleep) and the cooler does not stop what it can be a problem?. If that Windows clean reinstalled today.

Answer 1

Well, on the HDD, all the info from RAM is written before going to bed, all 4 GB
