Today I was looking to improve the performance on my pc I was watching some optimisation videos for the games I played and one guy mentioned GPU overclocking, I installed MSI Afterburner and followed a video guide in the guide they recommended boosting the core clock by 40mhz so I did it and I hit apply right as I hit apply my monitors said no signal, I thought it was normal since that happens when updating graphics card drivers so I was used to stuff like that happening when doing graphics card related things, It was taking an unusual amount of time but I figured to just let it do its thing after three minutes pass it didn't turn back on so I restarted my computer, still said no signal. Also some important details is that I believe it was just the monitors turning off because when it happened I could still hear the person in the video talking but I just couldn't see also after restarting the PC fans and lights still turned on.
