I was just idling on my desktop when suddenly my screen turned black and said that there was no signal. I rebooted my pc and it still said that i had no signal. I tried reseating my ram and graphics card but no luck. Please help me

Yes, my fans are still spinning. I could also have fried my cpu since it overheated when i was playing heavy games because my thermal paste is gone, but the no signal occured on my desktop, so i'm not sure
