In a medium sized skillet over medium high heat add shrimp and olive oil. Cook the shrimp 2-3 minutes until they are cooked throughout and opaque. Remove the shrimp and set aside on a plate.
In a large pot bring water to a boil and add the fettuccini and cook until al dente. Drain.
Meanwhile, prepare your Alfredo sauce. Add butter, heavy whipping cream, and cream cheese. Cook over medium heat and whisk until melted. Add the minced garlic, garlic powder, italian seasoning, salt and pepper. Continue to whisk until smooth. Add the grated parmesan cheese and let simmer until it starts to thicken. Add shrimp and pasta to the sauce and toss to coat.
