ARggh, I don't want to worry you debbie, after all I'm just a new guy around here too, and haven't got my status up
but invalid page faults are not too healthy.
Again, if I remember correctly: your hard disk will use a little space to pretend to be memory. When your memory fills up and needs more space it will swap older data out to the hard disk, and replace it with new stuff. If the old stuff is required, then its still on the HDD ready to be retrived, albeit a little slower.
Now, data in memory or HDD is referenced by pointers. When you want something the pointer says "ITS HERE ---->", but what happens if its not there? Data is 1's and 0's - if that data has been changed from 1 to 0, then that's bad.
just FYI, radiation from the sun will change a 1 to a 0 about once a month in a memory module, and will usually crash your machine because of it! Server use special memory to try and combat this as well as other problems... anyway - off track here...
its possible that (worst case) you have a memory problem, which I don't think because you would have a restarting machine more often. I think its better to say there may be a POINTER issue with your harddisk. If you really can't get it sorted by any normal easy way, do the drastic thing and reinstall Windows so that it purrrrs (if windows ever actually did/does).
