Virus C Problem: All sounds Clips and pops

[digitalflo]

Something weird happend, all sounds clips and pops, I thougth it maybe because of the midi/audio interface, so i decided to use my headphones just to check the sounds without any audio/midi conection (with the audiotion function)...but the sounds still clip and pop, i uploades a sample in sendspace, pls take a look.

Virus C: OS6.5 352 (also i reinstall the OS but after 15 or 15 minutes the clic and pops sounds again)

Is this connected to any sequencer via midi or anything?
Maybe your sequencer maybe dropping outta sync.

At the first time i tought it was by the pc/sequencer/midi/audio interfase, but the i deside to use the virus alone with no audio jacks and midi cables, just with headphones and pressing the buttons for audition, and the clicks came again :(
