Help Issues connecting to PC

[Insp.]

Got my Desire Z on tuesday, so it's pretty much new. Yesterday i plugged my phone into my computer and it worked perfectly, i managed to move photos too and from my phone's SD card and all was well, the menu came up asking me to choose a Connect to PC option and i chose drive and it worked fine. It was automatically on charge, and the preference to always ask for this menu you to come up is still on.

As for today, i cannot connect my phone to my pc, using exactly the same phone (obviously) with exactly the same cable that is placed in exactly the same USB slot, with exactly the same programs on. When i plug the phone into the pc, there is no prompt for connection choice, but the phone is shown to be charging, the phone is essentially not found by the PC, but the hardware recognises that it is being powered.

If i set the phone to debug mode i am prompted to chose a connection, but even when i chose for the diskdrive to be used, it does not work. I cannot connect to HTC Sync either.

I have been googling the issue and this forum with a couple of it's posts came up, but i really need user specific as the phone was working fine yesterday, then come 24 hours later, it's just stopped working in terms of connection to pc.

Any help would be great, thanks

Update: it's noticing a connection to the pc now, but i cannot access the diskdrive.

I had something similar happen to me on another phone. I just rebooted the PC and rebooted the phone and it worked after that. When you power off your phone, you have the option of rebooting the phone, give that a try as well as rebooting the PC. Let both sit for a few minutes after reboot and try connecting them again.

Done this several times, to no avail. The phone will notice that it's in the computer, iwill be prompted to choose a connection type, when i choose disk drive nothing happens. The PC sometimes notices the disk drive, but immediatly loses the connection
