Work PC (XP) Faster than Home Desktop (Win 7 x64)

Work PC: Windows XP, Dual Core E5200 2.5Ghz, 2GB RAM
Home Desktop: see TechComet: My Gadgets

The PC at work, although much slower than my desktop, seems to launch basic programmes like Google Chrome and MS Word much faster than my faster home desktop. I have no idea why. Originally, I thought it was because I had a lot of applications installed but even after reformatting it was discernibly slower.

As an example, when I click on Microsoft Word 2007 at work it opens up INSTANTLY. Literally, right after clicking on the icon it launches. However, at home I have to wait 1-2s.

The home desktop is not really “slow” in fact it performs very well in most cases, however considering I spent so much time and effort putting it together, it annoys me that my work PC (a stock Lenovo office desktop) is so much faster.

Obviously, if I started comparing games or Photoshop my Work PC would be slower, but for the most part I do basic web browsing and documents (and play the occasional game, or edit the occasional file on photoshop), so I want to really ensure my desktop is running as well as it should.

Finally, I do run a LOT of background applications on my desktop, but even then I don’t think it should be slower than my work pc.

Any thoughts?
