Aspire 5742-6602: Upgrade to i7 from i5

Hello,

I am new in this forum, I would like your help for upgrading my laptop. Firstly, my laptop was shuting down by overheating. After I clean it from the dust, again the same problem. Then, I changed the thermal paste, but problem continue. I decide to change the processor. Well, my current cpu is i5-480M with Socket G1/rPGA988A and motherboard is intel hm55 (ibexpeak-m dh). I found processors with  Socket G1/rPGA988A, the list below: http://www.cpu-world.com/Sockets/Socket%20G1%20(rPGA988A).html

Can I upgrade to Intel i7-820QM? 

I would be gratefull if someone help me.

Thank you
