I have a problem with my pc. I press the power button and while the lights (of the case and gpu’s) are on and the fans are working, the monitor seems to be off(?) Its light blinks like when my pc is turnt off. Is it possible that it got burnt or something? This happens for second time, i don’t know if i was just lucky the first time i remove all the cables from the motherboard and plug them back again and it worked but now it doesn’t. My monitor is an old Samsung one. What should i do?
