I use my PC only on the weekends and every time i get back home on friday it takes about 15 minutes of pressing the power button only for it to shut down senconds or minutes after, after this process it works like a fucking charm, when i boot it again the day after it turns on without killing itself on the fifth or so try. i have no idea what the fuck is wrong with it

specs
MB: Asrock FM2A68M-HD+
Cpu: AMD A6-6400K
gpu: Radeon HD 8470D chipset in the APU
ram: Kingston KF1600C10D3/8G (two seperatly bought 8g sticks, NOT in a 16gb kit)

it has not been like this for the whole time i´ve owned this box it was quite a recent development like the past month or two
