Windows 7: High DPC Latency - Please Help

Months ago, I started having high DPC latency issues, first time in about 2 years I had this PC, and first time ever since I've used a PC (about 21 years now). I tracked down the issue to a faulty wireless driver, I deleted the driver and throwed away the faulty WiFi PCI adapter... now about a month and a halve of enjoying lagless and gapless music, the DPC issues returned from no where! Yesturday I turned on the PC and when I turned on iTunes, and started scrolling down on my browser while searching for an email on my gmail it started lagging the audio. I was amazed, that no hardware changes, no drivers install and from one boot to another I started experimenting this huge problem. Here is what Latency Monitor says:


Highest DPC routine execution time (µs): 47199
Responsible driver: HDAudBus.sys (High Definition Audio Bus Driver, Microsoft Corporation)
DPC count (execution time <500 µs): 598413
DPC count (execution time 500-999 µs): 1326
DPC count (execution time 1000-1999 µs): 1122
DPC count (execution time 2000-3999 µs): 281
DPC count (execution time >=4000 µs): 234

Highest ISR routine execution time (µs): 45623
Responsible driver: dxgkrnl.sys (DirectX Graphics Kernel, Microsoft Corporation)
ISR count (execution time <250 µs): 1308494
ISR count (execution time 250-499 µs): 274
ISR count (execution time 500-999 µs): 607
ISR count (execution time 1000-1999 µs): 897
ISR count (execution time >=2000 µs): 1713

Highest pagefault resolution time (µs): 11160
Hard pagefault count (total): 261
Number of processes hit: 2
Pagefault count of hardest hit process: 247
Process with highest pagefault count: LatMon.exe (PID: 6864, DispatchMon and LatencyMon, Resplendence Software Projects)

I get audio lags when I switch from one software to another, when I scroll really quick in a web page, when I open a new browser tab (browser independant), when I use photoshop, it's almost every where!!!!



Please help me!!!! I'm desperate!!!!
