I started off reseting the ram as the computer was saying that there was only one but there is two in the system.
Once I had done this I rearranged the ssds so that they where not covering the motherboard so much.
I went to test that it worked, which it did but the monitor is saying nothing is connected.
I have replaced the psu, ram, gpu and retried each time. However, it still does not show that anything is connected to the screen. I have tried different cables, different slots yet it still does not show anything on the screen.
Any advice will help.
