Reply to Audio issues!!!!!!

OK , I know that there many many threads with audio issues and topics, but no threads have seemed to help me solve my problem. I have a show coming up in 2 weeks and something needs to be fixed now and I'm praying somebody has the answer for me.

To start, my computer is a HP Pavilion dv7 Notebook PC. Windows 7 x64 based Intel Core i5 CPU M460 @2.53ghz, 2534 MHz. 6 GB ram.

I use a traktor Kontrol s4 with traktor pro 2 version 2.1.3. When I first got it I don't recall audio drop outs at all. But I'll also tell you what my audio settings are at.
48,000 Hz sample rate, 256 samples process buffer, 1ms USB buffer.

I downloaded the DPC latency checker and I get huge random spikes. I tried turning off WiFi and the ACPI but doesn't do anything. I also updated the driver patch 3.0.3 on traktor kontrols updates and it didn't seem to adjust it at all.

What I have noticed is my load (CPU) meter is fairly low but extremely jumpy, and at the cracking/audio dropout points, it spikes to the full bar amount. Is that my issue, is there something I can do to fix that?

I'm new to this so I don't know if i provided enough information, if there's anything else that needs to be known let me know and I'll get back to you asap. Also, sorry if there's a thread like this out there but I haven't found it through the dozens I've read.
