A couple of weeks back I suddenly started getting a PAGE_FAULT_IN_NONPAGED_AREA BSOD. I have run tests on the RAM, chkdsk /f on the HDD, and changed the page file to a large fixed size. However every day I am getting a bout 2 of these. I can leave the computer idle for days and not have a problem, but if I start using it constantly early in the morning after about 5 or so hours I will get a couple. Thanks for any suggestions.
