Hello I'm new to the forum so I hope im not breaking any rules here. Anyway, yesterday my desktop was acting weird so i restarted my pc. My pc would turn on all the lights, fans, and the light of the mouse but no display on the monitor. I tried disconnecting the gpu and put it back again but nothing. It can not be my monitor because the little window that says "No input available for VGA" something like that. In fact I'm writing this with my computer as it turned on after I pushed the power button several times. But I wish to know why this happens as im sure my pc won't turn on back again if i shut it down right now, or at least it would take about 20 mins to get it back on. Any one know what the issure might be? Thanks in advance
