Macbook Pro internet issues

Hey so my computer knowledge is pretty limited and i'm not 100% which information is relevant so I'm just going to be as detailed as possible.

Alright so a couple nights ago my computer stopped loading about half of the websites that I tried to reach. I use google chrome and the problem first started when trying to access youtube and gmail. My connection status is fine but my browsers refuse to load the pages. I've tried firefox and safari and cleared all my browsing data for each. I've used multiple networks with the same result from each one. I've rebooted my computer, reset all my internet setting, tried using a guest account and tried a hardwired connection through my router, all without any results. Today I haven't even been able to load the google homepage, just a couple of various sites that I thought of. Only a few sites work and a lot of them only partially load the page. Itunes will load the itunes store but not all of the images appear. The App Store app gives a "cannot connect to app store" message. Skype signs in and I can make calls without any issues.

I just booted in safe mode for the first time and everything worked how it was supposed to. Chrome, firefox, safari, itunes and the appstore all were able to acces everything just fine. Rebooted again in regular mode and it's still messed up.

Not sure if this matters but I've got a 13" mbp with 2.4GHz intel core 2 duo, running OS X 10.6.8
