Yes, sure but i need to see your website to point out what causes the conflict issue.
But i can give you this TIP.
In Virtuemart related pages, look at the "source codes" and see how many jQuery (s) are loading. You should have only 1, which must be jQuery1.6.4 (this jQuery version is being loaded by Virtuemart by default). Beside jQuery1.6.4 there shouldn't be any jQuery. If there are any, have them not to be loaded. If you are using K2 component, most likely it loads an another, open the K2 components, click "parameter" and disable "jQuery loading". If any other component or plugin loads additional jQuery, have them not to load (at least not in the Virtuemart-related pages).
Cheers.
