well guys, guess what, after hours of disassembling the old 965m mobo and after thermal pasting 980m mobo,
………………………….. it worked, took hours but everything turned out great.
So now my specs are i7-4870, gtx 980m, 16gb, 1x 1TB, 1x 140GB, this is so cool.
wifi and everything works, the only thing that doesnt work are the 3 USB ports, will have to figure that out since out of the 3 non working USB ports 2 are old ones which were never replaced. Will have to check the 3.5mms and hdmi.
Very happy to see 980m in device manager though:)
