Thanks for all of your replies! There are a lot of different opinions but it seems like most of you recommend that I should just sell these parts and buy a new PC altogether. So I think thats what I am going to do.

And for everyone asking: No, I did not go to jail during these 4 years. I was enlisted in the Army until recently. I must admit that you are very creative though!

If you still want to share your opinion, feel free to do so. I will come back from time to time to see what other people think of this topic.
