Hey guys,
So I have recently changed my cooler to a 212 Cooler Master Hyper 212 EVO on my ASUS Sabertooth 990fx Mobo with a 8350. I use a XFX 550W PSU. My computer works great!... when it decides to boot!!!. If I shut it down and try to power it up the cpu led will light up. But when I remove the power cable from the psu and leave it for a while (half an hour, maybe less maybe more) it boots up just fine! no problems, no freezes nothing!! I tried to stress my cpu to see if it will fail but nothing! works like a charm! I also tried changing the PSU with a Corsair Gaming Edition 600W and I still face the same problem.
I am really worried because I fear that one day it will not power up at all!!! What do you think?
 
Two things check that the CPU is seated. Sometimes when you do a heat sink swap the thermal paste acts as a suction cup and you can slightly pull the CPU off CPU pins. The other issue with asus mb is if you over tighten the CPU heat sink. The added stress can end up showing up as CPU red led or red memory led.
