Glad to hear that your PC is working better. Right after the first couple of posts my thoughts were on Spybot as well. The symptoms that your PC was having are classic to adware. some files work the CPU very hard which in turn heats it up. This will of course heat up your keyboard. If the CPU heats up to much, it will shut down or short out to the blue screen as you found out. One thing you might want to do is to open it up and blow out any debris that has acumulated over time, especially on the fan.
Did your machine come with a CD writer? You can download all of your music onto CD's if you wanted to reformat your drive. It really isnt that hard to do. I like to reformat quite often to be honest. You will need to reconfigure your e-mail settings and stuff which is probably the biggest pain.
AS far as antivirus goes, I cant stand Norton. Mcafee is a good step above Norton, however, I am very partial to Panda. Panda doesnt slow your system down and it has great features that come with it.
As far as building a PC goes. Its fun to do.
