MSI P67A-GD65 & i7 2600 CPU starts for 1 min n stops.

Hi all. After cleaning CPU fan and plug it back, my PC does not start. When I press power button, fans turn for only 1 sec., and mainboard's led's light's on same, only for 1 sec. And it keeps happening in every 5 seconds till I unplug the power cable.

I started to unplug all components from mainboard. I also uncouple the board from case. Now only CPU&fan and RAM is pluged on the board. I press on, energy turns on for 1sec, and off. I keeps on and off continuously. Mainboard tries to work but just can't.

Probably either board or CPU is broken. Is this situation a typical problem? Should I go the MSI tech. service for board issue?

Is this problem of thermal paste material between CPU and mainboard?
thanks in advance

Hi, When reinstalling the CPU fan, have you cleaned the old paste and reapplied a new one?

yes, I have. and I bought a new akasa fan with its own paste on it. just installed it and the result is the same.

I will take it to tech. service but not sure if mainboard or CPU is the problem.

One more thing: when this starting loop is happening, I touch the CPU and it's not getting warmer even a bit. I suspect CPU instead of board.

It could be a CPU issue.
