I am suffering from a most mysterious problem (as are other Dell Studio Laptop users.)  There is a continuous DPC latency spike every 4-5 seconds which cannot be stopped by any usual means.  This normally may not be an issue, but I bought this laptop for high-end audio usage for high-end DJ mixing and it continues to create "pops" and "skips" in my tracks.  I need to get this solved but I don't know what to do.

Here's one detailed post on this same issue (in which Dell refunded the customer his $$$) -- this is some fault inherent with the Studio line:

It went unresolved with Dell's tech support and I wanted to see if anyone can help with this here.

I have a post here which details all of my issues:

As I mentioned in the above post, I disabled all wireless equipment (which did help with a large audio cut-out.)  But I still have this continuous latency spike which causes poor audio performance for my high-end external sound card.

So...how do I get these DPC latency spikes to go away?  Or can I?  If not, I want a full refund.  This has been a continuous problem since I've had this laptop.  And Dell's tech support, so far, has not been either knowledgeable or helpful.

Throw me a bone, anyone?  Thanks.
