Hi,

I'm a new member to this forum and I hope someone can help me out with my issue. My cpu lags randomly especially while playing audio and video. I followed the link here to get to the solution of my problem. But I'm kind of lost as to what I should do next...

Some snapshots of the Windows Performance Analyzer are attached below:

Oh I'm sorry I didn't see the reply. I thought I'd be notified via email. My bad.

I'm attaching the pic 3 expanded node.

I've experimented with all kinds of power modes, it lags even on high performance.

I can't download the trace. Can you upload it to mediafire.com or rapidshare.com?

do you use a Microsoft Live ID? It includes a SkDrive where you can upload 25GB of files

the NDIS driver causes some huge spikes:

Quote

Total = 3968 for module ndis.sys
Elapsed Time, > 65536 usecs AND <= 131072 usecs, 1, or 0.03%

Update the Dell Wireless 1702 802.11b/g/n drivers and test it again.

Yeah it's already up-to-date. I thought it WAS the driver cause it keeps dropping wireless connection back home. So I believe it's a faulty driver... I guess i need to get it replaced. I've disabled it for now.

Okay, so new problem... 0.0

My fan has been running very aggressively for the past two days.. I didn't know what the issue was so I go into Task Manager and discover svchost.exe is taking up about 30-50% of the CPU memory. Once I kill that task, the fan stops with its loudness.

I did a trace for it and attached it HERE. Is this also related to my wireless driver? Or have I been infected with a malware or virus of some sort? =/

AARgh this Dell is really driving me crazy.

no, it's one of those 4 services:

Stop one service after the other with the Services MMC Snapin (services.msc) and check which services caused this issue.

I tried stopping the services, the fan would still go on - some of the services such as Function Discovery Resource Publication didn't stop...

Now I have System Interrupts taking 15% of the CPU, whereas none of the processes are taking up any CPU memory in the task manager. Please see attached. =(

can you make a new trace? This also captures DPC/ISR issues.

Okay, ran the DPC interrupt. But the file was too large to put on SkyDrive so uploading a snapshot instead..

Btw, it is my Wireless cause when i disable it the system interrupt goes away.
