Dont turn the pagefile off, its a really bad idea. Essentially almost everything this guy says is wrong, so check before following. Better information here...

essentially let windows do its job and move the page file to another drive...
Well, I can just say from experience I have had page file turned completely off for the past 10 years or so and never had any problem. Like I said, having it enabled whether it needs it or not windows will use it and it will slow things down.
I have heard there are programs that dont like having it turned off, but I have never experienced such a program. I use photo editing/audio/video/CAD programs all the time and never had an issue. Even when I was running 2GB of RAM.
I wouldnt say its wrong to have it off or on, personal preference I suppose like most things. I prefer to get the most performance I can out of my systems. And pagefile, especially back in the day when almost every program wanted it, was a major performance killer for me. Now, I think its going the way of the dinosaur considering how cheap RAM is and you can pick up twice as much as you need for dirt cheap.
I dont base my statements I make off of google, I base them off the 13 years or so of experience I have had building computers and the various knowledge I have gained from forums such as this over the years.
If you feel that you need that stability than by all means leave it on. Im not saying for sure that having it off will or will not cause instability, Im saying that it never has for me. But every machine is different in its own respect.
