Cant active sync or hot syn my treo 755p

Question

Cant get my treo 755p to sync at all, even when setting up the palm desktop, I have the usb cable connected and then I have to press the sync button on the cable and still it wont sync. The hot sync
screen appears on my treo and it gets to the first little icon and then nothing occurrs.  The power light does go on when I connect it to the usb cable so I am assuming it is working in the very lest, the phone is getting charged by the usb cable.

When you "clean" uninstalled Palm desktop, did you do the procedure in the following instructions for the "clean" uninstall.
You should first make a copy of your data to have just in case something
happens. You can find your data files by going to C:\Program Files\Palm or
Palm One. Highlight your Palm Desktop username and right click and copy.
Then go to your PC desktop, right click on a blank spot and select paste.
For Palm desktop 6.2, look in the following location for the folders and files, my documents, PalmOS desktop. You will find the username folder in this location.
Now you want to uninstall Palm Desktop and remove everything that has to do
with Palm Desktop from your computer. Like the above folder, delete the Palm folder. Once this is done, you will need to delete some registry keys
from your PC Operating System registry.
Word of warning, going here and deleting the wrong thing can cause your PC
to not start up, crashing and deletion of programs and data. If you feel
you are unsure of yourself, see if you have a friend that can help you or a
PC technician that you can pay to help you. This will show them everything
they need to delete. To retain your current Registry settings, we need to do a backup of the Registry.
On the PC, go to start and run type "regedit" without quotes
Highlight MY COMPUTER, go to File --> export. Should pop up with a Save As
box. Current location is fine should be in My Documents or you can change to a location you will remember. In the file name box, type "Regbackup[todaysdate]" i.e. Regbackup07072008. Next, the hard part.
The easiest way to make sure your working with the correct key, highlight the key i.e. palm quick install, and press delete on your keyboard. It will ask you, are
you sure. Say yes. Do the same thing for all keys below.
If you make a mistake, stop what you are doing. And call a PC technician.
BUT do not turn off your computer.
The reg keys are as follows (Note: some of theses reg keys will not be here
but if they are delete them)
* HKEY_CURRENT_USER\Software\U.S. Robotics\Palm Quick Install
* HKEY_CURRENT_USER\Software\U.S. Robotics\PalmOne File Transfer
* HKEY_CURRENT_USER\Software\U.S. Robotics\Pilot Desktop
* HKEY_CURRENT_USER\Software\Palm
* HKEY_CURRENT_USER\Software\Palm, Inc.
* HKEY_CURRENT_USER\Software\PalmDesktopAutorun
* HKEY_CURRENT_USER\Software\palmOne
* HKEY_CURRENT_USER\Software\PalmSource
* HKEY_LOCAL_MACHINE\Software\PalmSource or anything else that says palm
Next reboot your computer
Then reinstall your Palm desktop from the CD and do a hotsync. If it asks
you for a username and you synced your device before, put in 'test" if you
did not sync before you create a hotsync name.
