hello everyone! This pc works fine last nyt but when i turn it on this morning it doesn't turn on anymore. every time i leave my pc for 3 hours it successfully boots up to windows but after 5-10 minutes, my system freezes with the hdd light always on, so i have to disconnect my avr to power outlet because power button does't work, after that scenario, when i turn on my pc it does nothing, but i hear(i actually see) the fans spinning, the power led besides the power button doesn't light up, so wait for 3 hours again and so on back to that "scenario" again but this 3 hours power led besides the power button light up. i tried removing components 1 by 1 but still no beeps, but after 3 hours on waiting pc boots, freeze after 5-10 minutes, unplug. tried also reseatting CMOS.
