Titan not detecting PC..help please! Not as noobie as it sounds

[danny6514]

Hi,
I flashed my titan with DCD's 2.3.0 kitchen. (added some OEMs myself)
Everything went well, until it finished.
Whenever I plug in my usb, my cellphone does not detect my PC at all.
Here are the things I have done in attempt to fix it:

-Tried syncing my titan with three PCs and three different wires, all with no luck.
-I hard reset two times and still no luck.
-I have tried both ticking and unticking "advanced network functionality"
-On my PC (Vista-32bit) I have unticked and ticked all possible options in Windows Mobile Device Center.
-Tried to relock it with Titanrelocker, however it just says no device detected.
-Went into bootloader mode and flash a new ROM from there. It went as if it's flashing like normal; however, once i got it started up i found out it wasn't even flashed...still the old broken ROM.

All these and no luck. Normally when I plug in my USB, there syncing icon will appear on top of my today screen, but now..it remains "EV"
Any help please?
