So i was having some issues with my computer randomly turning off for no reason. So i pulled it apart and pulled everything out of the mobo and plugged it all back in. now i managed to POST once after putting everything back together but now i am having the issue of nothing that is plugged into my mobo turns on at all. the fans, graphics card & its fan etc. I have one Solid Red led light up on my graphics card being a 4890. Any ideas?
