DPC (Deferred Procedure Calls)

Same problems exactly.  Just bought a Dell XPS 600, Pentium D 940 w nvidia 6800 geforce, 256MB PCI-E (problems started out of the box) .  Dell (lack of) support, as someone put it, had me scan for viruses, spyware etc then format drive and reinstall everything.  Needless to say after several frustrating hours on the phone and in front of the cp, the high CPU usage, choppy sound and video, studdering mouse movements are all still present.  I find it almost always starts after opening MEDIA CENTER.  They are sending a new video card.  I suspect, according to this forum, that replacing with the same card will not solve the problem.  I may just return the entire system (I will have to eat the shipping costs - my 2005fpw 20" flat panel is faulty too - backlighting leakage around edges).  By the way - don't buy a Dell dude!

I will have to decide if the shipping costs to return the machine are less than purchasing an ATI card!

Has anyone had any problems yet once they changed to an ATI card?

What ATI card is comparible in quality (assuming the 6800 worked

 

Before changing for a 7900 GT I tried an ati sapphire X800 GTO² with no problems too - no more dpc's so my advice is that you can take any card but the 6800 !!

 

Here is my last contribution for this topic about dpc's ,some will change their hardware as I did others won't . I talk about my own experience and what I think about dpc's and 6800 .

do what you want and good luck if you think that resolving problems by running some third programs to make dpc's disappear, is satisfying ...

 

cheers

I have the same problem as everybody else. Has anybody found any solution or is changing the card only thing that I can do?

...and add me to the list as well. My system:
- Dell Dimension 9150
- Geforce 6800
- Windows XP professional
I have tried everything I could think of, short of replacing my video card.  One remark I haven't seen before: when I play MPEG files , the DPCs fall back from 50% to 1~2 percent. E.g. run Media Player with an MPG-2 file. Even when I pause the movie and minimize the player, the DPCs stabilize around 10~20%, which is workable. When I play the movie, DPCs drop slowly. When I close Media Player, DPCs go back to around 50%.
I'm afraid the only option left is to buy an ATI card...

I guess I'll chime in here too.

I've been fighting this problem for days and I updated to 84.21 today and I'm still having the same problem (showed back up immediately after reboot).  I have a EVGA 6800 GS (PCI-E) in a HP a1250 system.

I'm starting to wonder if there is still time to return my card to NewEgg because this is just insane.  My old built-in ATI X200 was slow, but at least it didn't pull this junk.

I wish they'd just fix it because I'm quite happy with WoW and it would only be better if they'd fix this performance drain.  :(

At least this answers my question on why the crap my mouse does not seem smooth at all.
