Been awhile since I've had to re-apply thermal grease and stupid me put it directly on the processor and started it up. It powered up, then about 3 seconds later powered off, and repeated these boot cycles continuously. First thing I realized is that I was supposed to put the thermal grease on the heatsink, so I cleaned the grease off the CPU/heatsink and reapplied properly, but the problem still continues.
The only thing that throws me off is when I first bought this motherboard, it came DoA with the exact same problem (constant boot cycles every few seconds). So I'm not sure if its the CPU or motherboard at this point, so any help would be great.
Probably should've mentioned that this system was working properly for 2 years prior to this. The only reason I re-applied thermal grease is because my system would shut down every 5 or so hours of being on, and I discovered my CPU temperature idled at 95+ for all 4 cores.
Its like a sandwich, it doesn't matter if you put it on one or the other. I prefer to put it on the cpu die, because then you will know you will have it on all exposed parts.
If the computer doesn't boot into bios then there is probally a critical error. If the computer is cool to the touch after having been off for a few hours, then it is doubtful it is overheating. My computer takes around 15 mins to get to its normal, stable idle temp after being off for a few hours, so it shouldn't be overheating.
