Hello, I have a system with; xpsp2:home 667mhz 2gb(2x1gb) Kingmax 320gb Seagate Eemail@example.com P5B-PCI-E Recently I have been getting both Bad_Pool_Caller bluescreen STOP errors, and PAGE_FAULT_IN_NONPAGED_AREA. I have run memtests and uninstalled programs/reinstalled drivers and the problem still persists. I have attatched a dump from one of the PAGE_FAULT_IN_NONPAGED_AREA errors, I could also send in a hijack this log. These errors happen randomly, not at startup but when I am using the computer and seem to happen no matter what programs I use, except they do not happen at all in safemode. I have tried system restore, but this problem has been happening maybe once every two weeks for a little over a month, it only recently really came to my attention, so unless I restored to a couple months back (I only installed windows on this machine 4 months ago) I doubt it would do anything.
