Hi,

This PC is around 4-5 years old, the only older thing is a 1080 Ti GPU. The rest of the parts is a Ryzen 5 2600, B450 motherboard, and 16GB RAM.

Around a month ago, I went to turn on the PC and all seemed normal, yet no display. I then try to turn the PC off and turn and off again but it won't turn off so I force a powerdown from the PSU. From then on, the PC wouldn't even turn on when powered on. Finally I tasked myself to troubleshoot today, here were my steps:

1. starting off by simply changing the power cable. result: Pc getting power again but no post/display, not even any power to keyboard (no light).

2. Move HDMI cable to different ports of the gpu and monitor. result: no change.

3. Try different HDMI cable. result: motherboard logo appears with windows loading wheel, keyboard on, then back to no display, keyboard keeps working. When i then try and turn the PC off it either takes a bit of time or the PC just turns off itself after a minute.

Quite a confusing problem, since I found it weird that a change in cables appeared to be half the problem, but clearly there are still issues. Any help would be greatly appreciated, I would love to use my PC again!

Thanks
 
can you get passed BIOS and boot to Windows on a single ram stick in primary slot ?
Disconnect all unnecessary peripherals, backup drives, etc
Ensure GPU is seated fully in slot and connected to PSU, both ends fully home.
Is your monitor dodgy (borrow one or connect to different PC to test) ?
