Where do you see this green light? And when you say switch, do you mean the PSU switch at back, or the case power button?

Nah, cleaned the dust out and replaced thermal paste

So you removed the cooler? My first guess would be that the CPU cooler fan isn't connected, or is connected to the wrong header. (Or, possible but unlikely, that you cleaned it out with compressed air, over sped the fan and burnt out the header. But, while possible, that's very unlikely.)

There could easily be other causes, but that's my first guess and the first thing I'd try/check.

I'm going to hazard something with CPU or RAM if you were removing the cooler. Might help to see some photos of the current mounting, etc
