I took my components out of the case to clean and install fan filters on 2 of my fans. I put the computer back together and now it won't boot. The fans all run (including the GPU fan) untill I power it down but nothing shows on screen. The GPU (x1900xtx) has two red lights that light up. I never remember it doing this (it very well could have though.) I tried a different PSU (much better PSU), HDD, monitor, and removing a stick of RAM and none seemed to be the problem. I don't see any reason for my CPU to be the problem. However, when I took my heatsink off to clean I had trouble putting it back on because one of the plastic push pins wouldn't go into the hole (had to used needle nose pliers to get it to fit.)
Anyway I can be sure of whats causing the problem?
Thanks
