internet connection problem?

[secret18233]

So, i few days ago my computer/internet was working perfectly fine. i would go on youtube or watch movies online, and it would fully load, so i was able to continuously watch something w/o any pauses. but recently, every time im on youtube or watching movies online[ i dont dl movies], it would take a LONG time to load. everything loads perfectly fine, except videos.

I have a laptop and a PC, the PC is new, just got it a few days ago, and my laptop is virus free and i did disk clean up and everything. So do you think its an internet connection problem? how can i fix it? i dont have dial-up. i dont really know anything about computer, i just have a modem and stuff.lol. HELLLPP!!!!
