Intel core i5 7-400
Motherboard says h11om-a
Ram ballistix 2x4 ddr4
Psu black widow 500w bronze
Gpu sapphire nitro rx 480 8gb
I have been gone for a while but my sister says while playing overwatch the screen blacked out and the monitor said no signal. It's been like this for around 3 weeks. It works when I connect HDMI into the motherboard so I know its the gpu but I tried taking out the gpu and putting it back in but it didn't help my motherboard had other problems before such as not lighting up the lights for the case and the 4 pin power connector not working for and only working after several plugging out and plugging back in. Any ideas?

Okay, I'll see what I can do about that, but just a note every time I fidget with my pc it what say no signal but it would normally fix itself, this is the first time the computer just shut off in the middle of the game. Even when I had my old gtx 1050 it would say no signal sometimes. Maybe it's a problem with the motherboard?

Very sorry about the spam but I forgot to mention that my motherboard has other problems before such as not lighting up the lights for the case and the 4 pin power connector not working for and only working after several plugging out and plugging back in
