Ive been having this problem for a while now and Ive tried but cant seem to find what the problem is. So when i turn on my pc everything is normal it boots and i get to the login screen, than I login and get to my desktop (this happens only for the first time i boot my pc in the day), and after a min or less it freezes for a few seconds and the screen goes black. The first thing Ive noticed was that when the screen goes black 2 leds start flashing on my motherboard simultaneously its the VRAM and CPU leds. So i do what most ppl would do and force shutdown the pc by holding the power button. Than i power the pc on again, boot, login and everything seems fine it doesent freeze doesent crash works perfectly fine. If anyone knows or has had this problem it would help a lot if i could get some tips or potentional solutions. Thanks in advance.
