Please help with glitch in AA3.01 on 64bit Win 7 Pro/ M audio 192?

Question

This is very frustrating and it happens irregularly but repeatedly.  When recording, I sometimes get a very quick click or snap which is invisible on the waveform but can be seen in spectral view as a thin line running from top to bottom.  It can be edited out, but really slows down a production!
This sound is not caused by me.  It is far different from a mic 'pop.'   Yes, I use a blast shield, and am about a foot from the mic.   I might record 10 minutes and never hear it, or I might record ten minutes and hear it multiple times (maybe 6 to 10 times?)  Interestingly, I have never seen or heard it when recording silence,
I have a new PC with WIn 7 Pro 64 bit  I have 9GB ram, 2 x 1TB drives. Gigabyte GA-X-58A-UD 3R motherboard.
My card is an M audio audiophile 192.  There don't appear to be new drivers beyond what I have loaded.  In fact, when I load the latest driver, although it apparently loads, it does not show as such in the M Audio driver window. 5 10 0 5074 is shown, even though the driver 'says' it loaded  the new one successfully.
Any and all advice is welcome.  This is driving me crazy and maybe away from Audition but I love the program and don't want to replace it!  Thanks!

Thank you for your advice!
I use twin soundcards - one for professional audio - the other for Skype.  I
have tried moving the buffer to 4096, if I recall, but it didn't help.
Latency doesn't matter to me as I record sans headphones.
I can't really shut down everything on the computer since I must have access
to email and antivirus for email while I am recording.  My processor is an
i7 and I don't think there's any overclocking going on.  I can't remember
what the dialog was on the M Audio driver, but I seem to recall something
about several items being updated...
Would I be better off trying to emulate a 32 bit computer within the 64 bit
environment, or does that only turn everything down to 32 bit, not just AA3?
Another odd thing is I sometimes hear this glitch on playback where it IS
NOT recorded...  which I determine by playing back the audio in question
several times.  If not recorded, it'll glitch at a point, then on replay,
not.  When recorded, it's there in the spectral view, and each must be
edited out.  It's very annoying and time consuming.
Any other ideas are welcome.  I am uncomfortable with messing with the Bios
since I am not THAT technical.
