Is this a software or hardware problem

OK, for the past month and a half, I have had severe internet problems.

1) Internet: I use wifi. On an average day, I am turning it off and on about 7 times throughout the day to get the connection back. Everybody else in my house (non Mac users) don't have the problem that severe.

2). Charger: When my charger is plugged into the computer, the sleep indicator light stays on. I have to unplug the charger for and wait 5 minutes for it to start blinking or else when I open the MBP the screen will flash to the login window and flash off (along with the keyboard lights)

3). Restart: I have to restart this machine A LOT. Once, I restarted 4 times in a row and it still was acting up

4). Trash: I just don't have the ability to empty it. It scans and says that it has 327 items to delete...but it stays still for hours.

5). Today: I have really reached to the point where I am concerned. I opened Safari and loaded Twitter. About 2 minutes later I opened a new tab and went to my YouTube favorites and the page wouldn't load. It stopped the process on Twitter and every other application that was running internet. I tried to restart my computer and try again, but it seems like after 15 minutes of browsing the web, the pages become unresponsive.

I upgraded to Lion the day it was released and I'm thinking its the software problem...then again, look at all the other stuff that is wrong.

I plan on going to Best Buy (the place where I purchased this machine exactly a year ago). I have no idea what to do. Is going to Best Buy a waste of time?

 

Whoa. Thanks so much! I'll try all of that right now.
