Slow Internet After Switching Isp?

I just switched from xfinity to brighthouse networks after moving and now my desktop internet is extremely slow. I did lower my internet speed from 15 down and 3 up to 7 down .5 up. I realize that alone will make it slower, but this is ridiculous slow and its just on my desktop. My labtop is fine, but the desktop takes 15-20 seconds to load this page.
Have ran spybot, and windows security essentials scan and all windows updates.
Speed test on desktop:
Down: 6.8m (847kb/sec)
Up: .5m (61kb/sec)
Setup:
Amd Athlon II x4 635 @ 3.2 ghz
MB: Asus m4a785td-m evo
2×1 gb kingston hyperx
windows 7 home premium
any suggestions?
Everything else on the computer runs fine, all windows and programs open normally, however I can not connect to the steam network. Makes me think it is router or modem related.
Added information:
It takes about 10-15 seconds to load google, but once I do the search it only takes the .25s or w.e it normally takes, and I can search different things just like normal, but when opening a new web page it is slow..
Sorry for the long story just wanted to provide as much information as I could think of, any suggestions appreciated.
