Try upgrade to win 8.1 - as for the comment above win 8/8.1 is very thin svchost uses about 0.24% with the rest of the 8.1 modules adding up to a total less than half of cpu % load compared to say firefox at 5.4% 750 is a mid range card and will run applications and entertainment well but will struggle wiuth any type of 3d modelling as it is very much a 2nd class card.

NVIDIA GeForce GT 750M - gt is a baby gtx designed for entry level application graphics such as ms office.
