FIX: Replaced CMOS Battery, working just fine now (so far)!
Following Situation:
Shifted all my components from my old to my new case and exchanged my TopBlower for a Corsair H60 (2018) watercooling system. Was on my computer for at least 6 hours yesterday evening, working on a programming project and even when I started gaming later on I had no Framedrops, overall 10*C lower CPU temp., everything worked just fine. Tried to turn it on today in the morning and I saw the red CPU light on the motherboard turning on. Summary of what is going on/still working:
Red CPU light is always on
fans are all running
GPU fans are running
pump is running as well (CPU seems to be getting power as I can fell the pump head getting warm)
What I've tried/checked so far:
checked if the CPU (electricity) connector is connected right to the motherboard (it is)
removed RAM sticks
tried both of the two RAM sticks solo on every slot (nothing changed)
-> I noticed: when I plugged a stick to another slot, everything stayed the same when turning on, but after few secods the system turned of for 3sec. but turned back on and was in the same state as before
nothing is interfering on the back of the motherboard
User manual: "If a particular LED is on, that means the corresponding deivce is not working normally" (says nothing else, btw. thanks for troubleshooting Gigabyte ^^)
plugged screen directly in the motherboard, to see if maybe the GPU was just getting no signal, but the screen stayed black
checked if hold-down screws are equally tightened
System specs:
Aorus z270x Gaming K5
i5 7400
GTX 960 (Gigabyte Windforce)
2x 2133MHz RAM Sticks (not same fabrican, but tried them solo already)
Corsair H60 (2018)(Watercooling)
I really depend on this computer because of the projects for my programming classes (Android/Java) that are due mid december.
Already a big thanks guys, I really hope we can figure something out! ?
