Memory fault??

Hi again,
I occasionally get a message similar to "the instruction at '0x10041261' referenced memory at '0x00000007'. The memory could not be 'read'.Prewss OK to continue or cancel to debug" The computer seems to be running OK, & nothing untoward occurs unless I click on 'cancel' to debug. Whereupon the current program abruptly closes.
My computer is running WinXP, 512Mb RAM, Duron 1 GHz CPU, and 40 Gb HDD.
Can someone more knowledgable that I, kindly enlighten a bemused old fart?

 

I gather the message is from within windows and not at the blue stop (crash) screen (BSOD). Of course it is! You don't get OK messages on the dreaded BSOD
As it's from within windows, then it's possibly not memory related.
In the tools menu of Internet Explorer, go to Internet options and under the advanced tab tick Disable Script Debugging and UNtick Display a notification about every script error.
As it still possibly could be a hardware fault including memory you may need to swap out some memory. If your 512 memory is comprised of 2x256 memory sticks then you can remove one at a time and run only 256 for the purposed of testing.

 

Thanks for a prompt response Paul. I'll try your suggestion and let you know the result
