I got this error message or a similar one when I was using programs like Firefox or when I opened Safari and a few times when playing games. except it said the name of the program/game I was using instead of DAP.EXE
The Instruction at "0x00660fbd" referenced memory at 0x00000004". The Memory could not be "read".
Click on OK to terminate the program
Click on CANCEL to debug the program

It started about a year ago I think, but recently I have been seeing these errors more often. About a year ago my video card died, and a few months after that I added another hard drive and went from 1gb to 2gb of memory. I updated itunes and safari in XP last week. I also uninstalled a few programs I don't use anymore.
Here is a list of some of the programs an error has happened in
Firefox (usually when I have multiple tabs open)
Safari (right when I opened it)
I have also had games freeze on the loading screen sometimes
lately when I run firefox it will sometimes freeze for a few seconds when I have more than a couple of tabs open
About a month ago when I was booting into Vista it ran the chkdisk thing on the hard drive vista is installed on
I have gotten the S.M.A.R.T. warning thing for one of my hard drives right when the computer first turns on saying to back up my data, etc.
About a week ago I ran memtest86+ for 15+ hours and didn't get any errors.
I also usually leave the computer on overnight either to download program updates or to run the virus scan because it takes about 10 hrs to do a full system scan. I have about 1.5 Terabytes of Hard drive space so I don't know if this is how long it would normally take or not. I am using AVG as my antivirus.
do you have any other ram to try ?? the ocz ram is NOT on the qvl list in my manual [a8n-sli se],,although i am presently running 2x512 ocz 3500,on this board,it runs well ,,but,, will not allow any playing around at all,otherwise,,i would get the same sort of errors that you are experiencing ...
another item to keep in mind,,some mobo's do not take well to 4 sticks of ram at all,although you might try using click 1?? in the bios,in the memory timings/settings,,otherwise you might have to replace your ram..
