Pacer .sys

[zebra3]

I have a Dell 8300 XPS , Windows 7 Service Pack 1 64 bit. 16GB Ram, Video Card Nvidia GT 430.  Within the last few day's I have been getting a warning in the Event Viewer that my display driver was restarted. I'm sure there was one of the ballon pop-out's warning me of the situation. (My wife is usually on the computer and probaly paid no attention to them). There has been no BSOD. I found the DMP file not in the Mini Dump File but in the WatchDog file (Don't know what this file is).

I just had two event's today. I used the program blue screen view and they both showed the "pacer.sys file" causing the error. The video card driver is the latest and also the BIOS. I ran the SFC verify program and it stated that everything is OK.

I attached the file's below. What would be the cause?

Download BlueScreenView:
http://www.nirsoft.net/utils/blue_screen_view.html
unzip downloaded file and double click on BlueScreenView.exe to run the program.
when scanning is done, go to EDIT - Select All
Go to FILE - SAVE Selected Items, and save the report as BSOD.txt
Open BSOD.txt in Notepad, copy all of the content, and paste it into your next reply

I asked you to please post the results rather than upload a text file, but okay.

Look in Device Manager - are there any yellow or red symbols? And you said you had two "events". Please describe those events.

There are no yellow or red symbols in device manager. The two event's that I described were in the "Event Viewer" They both were Warning's Source: Display Event ID 4101. Display driver nvlddmkm stopped responding and has successfully recovered. I found both of these event's in the Kernel log file under Watchdog.

Both were listed as DMP files. which is what I attached after the two event's happened.

Try re-installing your vid card drivers...or roll them back to the previous version.

Ok. For now let's not worry about the event viewer. I'm have a little trouble following everything here - are there any issues with your system? Is it running okay?

[zebra3]

As far as I know everything is running fine. About 3 month's ago I changed video cards from a ATI?Radeon HD 6450 to the current card Nvidia GT 430 the driver's are the most recent.  I usually run the Dell support Monitor which scan's all the hardware and show's everything is O.K.

For the time being I can roll back the driver's and see what happen's.

[Allan]

I guess I don't understand. Why are you doing anything? If the system is running okay leave it alone.

I didn't state that correctly. What I meant to say if the problem's keep's coming back that's one of the option's I will try.

Thank you very much for your help!
