prints skewing to minus x axis

So ive had my ctc printer for a while now and its been going fine until a few weeks ago, when it started printing with a lean to the left.

Any help would be appreciated.

bit of an update vibration has gone way up, went to my computer room to see the printer dancing off the desk. Didnt fall luckily, so imassuming there is something wrong with my x axis stepper motor.
any ideas?

i had the driver for my X motor die on my very first print. but then it just got stuck where it was jumping back and forth over a few milimeters. (the printerhead not the printer itself. Stepper motors are really reliable, as there is bascly just 1 moving part. if there is any flaws, it is usually something else. frayed wire, or as in my case, driver flaw.
