Slow Internet Help, Please? :)?

I have an HP 2000 Notebook PC (HP laptop) that has Windows 8.

Previously I had been having problems where it would go to a blue screen and say "windows has encountered problems and has to restart :( " And it would restart and prompt me to send the details to Windows. It happened at a crazy frequency. The tech support people blundered and never got down to what can solve it or what was causing it even.

But I switched from Firefox to Chrome, and now it only does that on occasion. So I'm assuming that's Windows problem. After all the updates it hasn't done that in a bit.

That's just some background on laptop problems.

The internet NOW. I'm using Chrome, and it keeps moving pretty slowly....if I refresh it sometimes the page I'd wanted to get to will pop right up, other times I just have to close out the internet completely and re-start it. It's getting irritating. And I don't understand why this is happening, and I have all the bars on my Wifi.

What my question is, (sorry for not really getting to the point until now:p) is, any ideas on anything to delete to make the net go faster, or just any ideas on how to get it to go faster? Or am I stuck on slow?

(I have U-verse/AT&T if that makes a difference)
