i went to the virtual memory thing first, and i found what i said. i don't know specifically what I should do in regards to that. the two links there say similar things. it says about 3x the initial size in the first link. I mentioned that i found that page files are supposed to reduce th work load.
Disk check did not show any errors at all on any disks. That is why i did not need to run diagnostics.
I am wondering if what i have reported afterwards could have been related to the errors. These sudden page file errors did not occur until today. I installed some software yesterday, and copied files at that time. I also transferred files from the external drive to the internal drive today, then i did a search.
If there aren't any hard drive errors in disk check, but the windows event log is reporting a disk page file error, i thought something in the time frame could be related.
