    Recently after I tried to add another cooling fan into my NZXT phandom case my pc would turn on and freeze. Sometimes before the windows logo even comes on my mouse and keyboard lights would turn off. I have since disconnected the extra cooling fan but the problem did not go away. I have checked my temperatures and they are not very high. My only thought on this problem is that when I also tried to add a 2nd extra fan (which did not fit well with its clamps due to the graphics card being right below the location) onto my north bridge which at some time had a heat problem as all with this motherboard do but was fixed with a cooler. In trying to add the 2nd fan I might have moved the cooler slightly and messed up the thermal paste connection. However I am not completely sure because my temperatures seem normal and are not in the high range. The only problems or hints I can see are the freezing after several minutes after startup, not reaching the windows logo at all, and my mouse and keyboard lights not turning on when the pc does not reach windows logo before being a black screen.

    When your computer gets a black screen only sometimes, it usually means your ram is on the way out..For example if you boot your computer and it doesn’t work, then go back an hour later, and it does work, your memory is playing up. You can try taking the ram out, gently cleaning it with an antistatic cloth, and replacing it. This may solve your problem.
