First, I checked and noticed that I had my C: drive on automatic defrag and it last defragmented my drive a few days ago so no problem there.
Next, I checked and I, very ignorantly, already had 3 restore points on it already...the last one from just a few days ago.
Well, I did find one folder that is huge..my old Windows.old folder. I have had Windows 7 Ultimate for a while so getting rid of a 32.5 gig Windows.old folder will really help.
I do need to, and will, check on that page.sys file for sure.
I do have large hard drives but I partition them so that I can have all similar files in one space, for example all my videos on a D partition, photos on a E partition, etc., etc. I usually make the C: partition strictly for Windows and so I do not make it too large. That was the primary mistake as I was not thinking about backups, restore points, etc.
And, evasive, I completely agree about being given a notice when a restore point gets kicked off. My computers run pretty good but I guess I am just paranoid about installing something like a virus/trojan/worm,etc. protection program breaking the connection with my wifes job.
Also, Karlsweldt, all good points..especially that last sentence. I am going to have to investigate that one for sure. Of course, I am going to follow the instructions in the other sentences also.
