My Faster PC recommendation

I think of myself as someone who know a little about computers.  More than the average user.  I can change a hard drive or a power supply, run msconfig, and I am pretty good with a lot of software packages.  However, when it comes to trying to speed up a PC that you have had for a while I find the best solution so far is to use My Faster PC.  I have bought it for 3 different computers and I have been really happy with it.  The cool part about it is you can download it for free and they will tell you how many problems they have discovered.  After that if you want the program to fix the problems you buy it.  I have had really good luck with it.  The only problem that it didn’t solve so far was the HP laptop that I have.  I think that is just a memory issue so I am going to buy some more and see if that helps it.
