I just bought some new case fans so I turned around my CPU cooler to improve the airflow. Obviously I had to change the paste and after setting everything up (2x 120mm connected to mobo cpu1 and cpu2, rest connected to PSU) my pc wouldnt start... After some troubleshooting I found out it was my second DIMM slot... Whenever I put either one of my ram sticks in there my pc turns on, HDD+ all fans + GPU but the screen remains black and after 10 seconds it restarts on its own. It just keeps starting up and shutting down on its own until I turn off the PSU... How the heck did that happen???? Is there any hope or do I need to buy a new mobo?
CPU : i5 3570
GPU : MSI 7870
Mobo : Asrock h77m
ram : crucial ballistix sport 1600 c9
PSU : XFX pro 650 core
Checked the pins. I think I saw a bent one but when i tried to straighten it with the backside of a needle it wouldn't move. I'm afraid it might be broken. I couldn't see clearly, not even with a magnifying glass. repositioning the cpu didnt help either. Same problem. PC just won't boot when DIMM slot 2 is occupied..
