"What do you suggest I do"
After 8 years your current computer is telling you what to do - it's time to buy a new machine.
You can't transfer 'Mt programs' onto a new hard drive because each installation writes keys into the Windows registry, and the new machine will have no information about all that. You'll need to do fresh installations of anything you need.
Your new machine will be running Windows 7, or depending on when you buy it, Windows 8 may even be pre-installed. You'll probably find that there are newer versions of much of your software, specifically designed for those versions, but older versions may still run.
AVG and so on will be no problem, you can just download new versions to the new computer.
Make the move - you'll be amazed at the difference it will make.
