Jeff Lanzarotta Posted July 10, 2005 Share Posted July 10, 2005 Hello,I having problems with an excessive amount of DPCs!Basically, this is my systemAMD64 3200+ASUS A8V-ENVIDIA 6600 PCIx2GB Corsair DDRWireless 3com nicWireless Logitech mouse and keyboardWindows XP Pro /w Service Pack 2I'm not sure what the heck is going on. Every new seconds, maybe 10, I get a spike in DPCs. The spike ranges from 4% to 40% CPU!!!!! I can tell this by using ProcessExplorer. When this spike occurs, my mouse stops responding for a brief second or so... VERY ANNOYING Well I'm tried switching out the netword card, nothing... I've tried a new keyboard and mouse, nothing... I've updated all the drivers, nothing...Also, I just did a complete format and reinstall of XP and Service Pack 2, nothing changed...The ONLY software I have installed is:XPService Pack 2NVIDIA drivers3Com network driversFirefoxMacromedia Flash pluginThis is very FRUSTRATING :'( This system should not be doing this. Can anyone possibly give me a clue on what could be causing this and how to fix it?Regards,-Jeff Quote Link to comment Share on other sites More sharing options...
Rons Posted July 10, 2005 Share Posted July 10, 2005 (edited) Are you running PE 9.12 for 64 bit or XP ?http://www.mrtech.com/news/messages/4893.htmlLet us know. :'( Edited July 10, 2005 by Rons Quote Link to comment Share on other sites More sharing options...
Webb Posted July 10, 2005 Share Posted July 10, 2005 I had a similar problem a while back. I'm hardly an expert in deferered procedure calls but I was able to fix it - essentially, something kept trying to access the CPU but couldn't complete its task and got into a vicious loop.Here's the thread. Hope it helps. Quote Link to comment Share on other sites More sharing options...
Jeff Lanzarotta Posted July 11, 2005 Author Share Posted July 11, 2005 I'm using PE 9.12 for XP 32 bit, not the 64 bit version. Quote Link to comment Share on other sites More sharing options...
Webb Posted July 11, 2005 Share Posted July 11, 2005 PE should let you track down the offending process and correct it - probably a bad driver. Quote Link to comment Share on other sites More sharing options...
Jeff Lanzarotta Posted July 11, 2005 Author Share Posted July 11, 2005 Really? I'm not quite sure how PE would tell you where the DPCs are coming from? Any hints?I did update the AMD 64 driver last night. DPCs are down to 1.56 percent, which isn't too bad... Quote Link to comment Share on other sites More sharing options...
Webb Posted July 11, 2005 Share Posted July 11, 2005 PE will tell you which process(es) is/are causing the CPU spike.Expand the view so you can see as much information as possible. Quote Link to comment Share on other sites More sharing options...
