I didn't realize your were running 4 gigs of RAM with XP. The tech is correct, XP will at the most recognize 3.5. I am also wondering if the motherboard had voltage issues with 4 gigs that needed to be tweaked. But since you have XP it becomes a moot point.

You'll want those 4 gigs if and when you ever upgrade to Vista 64, but by that time MS will probably have a new OS released.

So im running 3gbs now and its running perfect. I have some things printing and the memtest running in the background..and everything is working out great. No shutdowns or anything..guess that extra gig was killing me there with the bigger projects that we print..and all of the errors and faults that we had are now gone for these past 2 days. Seems as though that was the big problem. If anything else arises..ill let you guys know. Other than that.. THANKS FOR ALL THE HELP!!!

That is RAM for you. It can cause all kinds of issues. Thanks, icedesign, for getting back to us and letting us know it has been resolved. Many people fail to tell us the good news.
