I was working on my computer, then it stop sending video signal and the gpu fans started to work at their maximum capacity.
Now every time i turn it on, the gpu fans start working fast, with no video signal.
the motherboard shows a white led up beside the ram, if anyone can explain what does that mean?
Specs:
Ryzen 5 2600x
16 gb(2x8) ram corsair vengeance 3000 mhz
motherboard asus strix b350-f
rx 580 8gb aorus

I have tried to connect everything again, i changed the thermal paste of the gpu.
Any suggestions?
