Hi guys,
I recently took apart an old pc, and it was working perfectly fine. I used some of the parts for a build that didn't end up working, so I decided to rebuild the system.
The system no longer displays anything when I boot it (the fans do spin) and everything else seems to be fine. I have tried reseating the ram and plugging everything back in already.
Any help will be greatly appreciated!
