So I have a prebuilt pc that I bought from andromeda insights, and so far it worked really well. That was until an hour ago, when I was on yt and my screen glitched, task bar disappeared, my wired speakers disconnected and everything went wonky. So i panic restarted by holding the power button, but when i turned it back on, there was no display. I've seen some tutorials as im not a pc person myself, and i reseated the ram, gpu and the cmos battrry for about 5 mins. Nothing still shows on my monitors. I used a displqy port cable on my main monitor and i lt doesnt work, while connected to gpu. I basically tried a bunch of cables from a bunch of different port on 3 different screen and none work. Though i only have 1 display cable atm. Ive had pc for about a year now, whaylt should I do?
