For the past few weeks, when I boot up I receive error messages inchlidng explorer.exe application error; the instruction at 0x35f752c4 referenced memory at "0x35f752c4" The memory could not be written; "Windows explorer has encountered a problem and needs to close. And, generally, the screen goes white, my icons remain, and the headline "Active Desktop Recovery" appears. I generally, return to active desktop and things seem to be OK, but the process is beginning to concen me. Any idea what might be going on? thanks.
