Specs: i7 8700, rtx 2070 super, seasonic Focus 80+ Gold 550W. So this morning my pc was working just fine. Turned it off, went outside, came back and when I tried to turn it on it didn't do anything for like 2 seconds then it turned on and immediately turned off again. I took a look inside and found out that the a red LED labeled CPU was also flashing for that brief moment the pc was on. Firstly I removed my cooler and the cpu. Tried turning it on without a cpu and it did the same thing. Changed the thermal paste as it wasn't changed for a while and put everything back. Tried again and same thing. I removed my gpu and tried turning it on again. This time it was turning on and off endlessly, on for like 1-2 seconds and off for like 1-2 seconds. Tried to short the green wire and the ground wire on the 24 pin connector to see if the psu is dead. It was not it was working fine. The psu fan was spinning. I have two sticks of ram (2x8GB) an i tried using just one. Switched it around, tried all logical positions. Same thing. Any suggestions on what I could do?
