"Hi bro, can i upgrade my HP g6 pavilion laptop with i3-2330M to Core i7-2860QM, i7-3632QM, i7-3740QM or i7-3840QM all these processors work on same socket Socket G2 / rPGA988B. Is there any possibility?"
I would say yes there is a good possibility - i think the best bet would be the 2860QM because it has "Sandy Bridge ' microachitecture which matches your current 2330M. The other 3 processors have 'Ivy Bridge' so that could be problematic.
Here's the thing though - your current processor is 35 watt - the 2860QM is 45 watt - which means more heat. I think you'd be ok though as long as you thoroughly clean the cooling system and use good quality thermal paste. I've replaced a number of 35W processors with 45 watt ones and have yet to have an issue.
Needless to say there's no guaranty that it would work but .... if it did, the performance increase would be substantial!
Brother, first of all thank so much much for response. however I got into some different problem, had some big issue yesterday, nothing to do with CPU upgrade.Its just my g6 pavilion was getting too hot so thought to give it some cleaning. Had to open each single piece of laptop just to clean fan, remove dust absolute nightmare. Here is sequence of events:
1. Disassembled laptop, each single screw, battery, dvd, ram, wifi, sdd, keyboard, removed all cables etc.
2. Opened Heat sink however one of corner metal thing (possibly called fin??) broke while taking heat sink out.
3. Cleaned fan
4. Cleaned CPU & bottom of heat sink with Alcohol swabs,put new arctic cooling thermal compound
5. Put heat sink, fan and everything else back in order. Re-assembled!!
6. Started laptop and now got no display at all. Power, caps lock and wifi LEDs are ON on keyboard. Fan is ON. Laptop making normal sound as it normally does. No beeps etc. Laptop temperature seems normal.
7. Tried to connect to additional LCD using VGA and HDMI no luck
8. Have tried removing battery and hold power button down for 30-60 secs couple of times and tried restart still no luck.
Have no idea whats possibly could be wrong. Please advise if there are any options left.
Thank you

Update 05/OCT/2017: Finally managed to sort out laptop, display is back. had to re-open each single component and reassembled. Its been working fine now and so far. Dropping plan for cpu upgrade however fairly sure and agreed with robert600, i7-2860QM should work. I would also say HP g6 pavilion got worst design. Opening whole laptop just to clean fan doesn't make any sense. A big NO to HP laptops in future...
