I have a users PC that has explorer.exe (not internet explorer) that crashes. I have Googled it and gone through many of the fixes. It is Win2k, IE6 sp1. I have applied all the latest MS patches, re-installed IE6 and several other minor tweeks. It doesn't appear to be hardware. I ran tufftest pro on the HD and memory.

One of the errors that is seen is "The instruction at '0x...' referenced memory at '0x...' The memory could not be written." Also will get a similar error saying the memory could not be read.

I have not, that is my next step, tried ripping IE out in the registry and totally re-installing. Many of the google hits refer to repairing IE.

Any other ideas?
