Hi Guys, 

I have a strange issue I am hoping someone can help me with. I have just upgraded my PC and everything works great however when I am doing programs to reinstall or games I my speed drops to 10% of what it should be for the whole network. I can understand it dropping a little bit but this never happened before. I am on a 80mbs line and when I am downloading the whole traffic drops to 8mbs or less. 

Any ideas because this hasn't happened before and I have no idea what has caused it beause nothing has changed with the network itself. 

Thanks in advance.
