Is the driver l160x64.sys, version 2.4.7.27 the latest driver for your Atheros L1 Gigabit Ethernet 10/100/1000Base-T? Also make sure all offloading options are enabled in the driver settings. Does this help?
No its not the latest, but I downgraded from the latest version to see if that was the cause and downgrading/upgrading doesn't make a difference. If anything upgrading makes it worse....
But, I downloaded tuneup utilites and it found some bad drivers from a program I used called sandboxie. After uninstalling it and making other changing im actually in the greens/yellows with spikes of red again. Ill go ahead and send you the trace of it.
Im actually able to play music/games now without cracking/popping sounds. Heres what dpc checker looks like :

make a new trace, please.
pm sent,
I left my pc on all last night, before I went to sleep I check dpc latency checker and it showed me in all red with some yellows.
Woke up this morning to find myself in high greens low yellows, and random spikes of red. Power went off due to a large storm here and guess what, im back in all high reds. meh...

So after uninstalling diskeeper and changing back to ahci.....computer runs much better but still left with netbt.sys and ndis.sys and usb one causing high dpc. I don't know what could be causing this.....and I don't know what to do...

USBport i still an issue, but 2 others also have huge impact. The ataport.sys causes some spikes. I can see that the Diskeeper service causes an extreme CPU usage. Your HDDs seem to run in IDE mode and this seems to cause the ataport DPC issues.

So stop Diskeeper and only use the Windows internal defrag tool which only runs if the PC is idle.
Now the interesting part is netbt.sys. This is NetBIOS over TCP/IP. it ha only 24 DPCs but all of them are horrible slow (at least 2000µs).
Try to find out which service program depends on NetBIOS. Maybe it is Diskeeper which communicates this way.
Its weird because ive had diskkeeper installed for over 2 years and no problems till 3 days ago. I know for a fact I installed windows with ahci, so I don't know why my hdds would be reading IDE.....welp time to start uninstalling one by one.

please make a trace without running DPC latency checker in background. i got wrong results when the tool runs.
sorry about that, pm sent

please make a new trace without all USb devices.

*EDIT
Disabling Atheros L1 gigbit ethernet controller reduces dpc latency into the green/yellows. Removing all usbs while the network controller is disabled puts it in green permanently, even though its higher than it should be(800us). Two days ago when I ran dpc latency checker I was in the 300-400us with everything on with spikes once every 5-10mins into the 100k+ us range.

Looks you have USB issues:

Total,this is too high. Does it occurs if your unplug your Logitech devices? The Logitech drivers (LMouFilt.Sys, LHidFilt.Sys) are involved. If this doesn't fix it, unplug your USB phone and your USB HDD.
Ive unplug all usb devices, it does lower the latency but its still extremely high.
This high DPC latency just occured overnight, when I was streaming video or playing music everyone once in a while I could hear a popping/crackling sound. So I dled dpc latency checker and found out about every 5-10mins the latency would spike to 130-200kus. So I restarted my comp and the dpc issue become even worse, more reds and yellows than before(was all green with 1 red spike every 5-10mins). Then I ran some scans and stuff and restarted my comp again and Ive always been in the red...
This is what dpc latency shows with all usb devices unplugged.

make the xperf trace please and upload the compressed (as 7z or RAR) DPC_interrupt.etl (zippyshare.com, mediafire.,com, dropbox, skydrive) and send me the link.
I pmed you that link
*EDIT
Im getting tons of "chrome could not find this page" and dns errors, theres nothing wrong with my internet I just have to keep refreshing until the page loads. Very odd, never had anything like this happen before.

Hey guys ive ran into this high cpu usage/high dpc latency issue about 2 days ago. I don't know what the heck happened but my computer is CRAZZY slow. Ive tried to disable drivers/update drivers and nothing has worked. Did trojan/virus scans nothing. Any help or info would be greatly appreciated, thanks.
Here are some screenshots:

**** that was it.....I ran the verifier.exe scan...or I thought it was a one time scan when I was having constant 400us and 130k us spikes dpc.....I didn't know it stayed on always. Then when I restarted my comp, I was completely in the red.....I feel real dumb.
My spikes are now 500us and its constant around 80-200us......great job man I really appreciate it! My computer runs much better than ever before, and just yesterday I had my windows disc ready to format this computer cause I was so irritated.
Life saver man, TYVM..
