I was playing a game/browsing internet and then PC crashed resulting monitor going into power saving mode as it didn't receive any signal no more. Can`t tell if there was a reboot or PC still stayed on because I don't have case speaker for warning beeps. PC can be turned on and off as normal by power button, all fans seems to be running like before. <span style="text-decoration: underline;"><em>Things I tried so far</em></span>, changing video out`s from VGA, connecting tv through hdmi, removing dedicated VGA and plugging monitor cable into Intel HD video out, removing and changing RAM slots. None of that brought me any results.
What I need to achieve is to find out which component is bad to send it back for replacement. So far possible scenarios involve CPU and motherboard...
Any advice to help me out here?
P.S. I don't have any spare parts to replace existing ones for finding out if they are faulty
