How do I fix a glitchy Vaio touchpad?

Here's my specs:

Sony Vaio, VPCEB4LFX (bought oct. 2011)

Win. 7 64-bit

Alps touchpad

I seldom use the touchpad and instead use a USB mouse. I used the touchpad last without glitching a little over a week ago. Now when I go to touch it, it isn't stable or accurate, sometimes jumping around.

I contacted Sony tech support and followed their online troubleshooting and reinstalled drivers and driver update. No change. When I run it in recovery mode, the touchpad is stable. When I run in safe mode, the touchpad is glitchy but not nearly as bad as in regular mode.

Sony is telling me I need to turn it in for service. I am unable to do that as I am out of country on military assignment. I believe this is a software issue which I could fix myself if I could just isolate the situation. I think theres some kind of software conflict somewhere.

Recently I have installed:

Medal of Honor: Pacific Assault

Star Craft 2: Wings of Glory

Skype

Real Player

Could one of these programs be causing me the hassle? And does anyone suggest a clean re-install of windows to see what happens?

::EDIT::
I fixed it on my own. Here's how, for those of you with the same issue:

You must delete the Apls device driver completely from your system. For some reason there's an incompatibility on a 64-bit machine that even the Sony website's driver has issues with. This forces the microsoft version to kick in, and BOOM! Problem solved. The only downside is you lose the 'spiffy' functions such as zoom/two finger nav/etc. don't work with this mode, but since I hate those functions anyway (and had them disabled in Alps settings) it is not an issue for me at all.

I wrote back to Sony to give them an update and tell them Alps sucks. Lets see if they listen ::eyesroll::
