Wifi hangs up on start-up, and computer hangs after using internet for 5 min.

Question

HP Touchsmart tm2, using Window's 7 64-bit. There are no error messages popping up, but what happens is I start my computer, and my wifi/internet connection icon seems to freeze while loading possible internet connections. If I turn off my wifi and then turn it back on using the button on the side of my computer, it seems to work correctly, then.
But, when I get on the internet, no matter what site I go on to, my computer will just hang up after being online for at most 5 minutes. Mozilla Firefox will go into a Not Repsonding mode, and I can't minimize it or click/open any other programs. CTRL+ALT+DEL doesn't work, and when I hover over any icon, nothing seems like it's recognizing my mouse. The mouse moves, though, and the time even keeps going (it'll change from 9:13 to 9:14 and so forth).
It ends up figuring itself out, though, after another 5 minutes (literally an entire 5 minutes) and then seems to work okay. 
Recently, I updated CCleaner to the newest version, cleaned out my internet cache, defrag my computer using Defraggler, used CClean to also wipe by free space, and updated Avast! Antivirus to the newest version and ran a full virus scan with no threats detected... :/

Hopefully No real Damage was done.
A Surge Protector works fine with items like Lights, Lamps and small electrical items.  Where the problem arises is with Computers, which are precision electrical devices.  The only real protection is a Battery Backup like an APC.

When there is a Power outage no matter what the source. can also create tremendous Power Surges. This can happen when the electricity is turned back on and can cause frying all of your Electrical Appliances.
Having an APC will save all of your Computer Equipment including your Modem, Router, Printers, Scanner, Computer, as well as Phone lines.
A simple Surge Protector simply isn't enough protection and especially the cheaper models.
Here is the simple way to check and see if your equipment is still operable.
Turn your Computer clear OFF and pull the Power Plug
Pull the Power from both your Modem and your Router.
Wait a minimum of 5 minutes. After the 5 minutes Plug in your Modem and wait a minimum of 3 minutes.
Now plug in your Router and again you must wait 3 to 4 minutes.
Now you can plug in your computer and restart it and don't touch anything.  If your computer starts up then you got lucky If not you will probably need to take it to the genious bar at your closest Apple Store. Chances are that your computer has components that have been fried from the power surge. Good Luck and hope your computer restarts.
