As Vitaliy points out, replacing the joists is completely unnecessary, however, I did look into it and came across this article: http://ifbholz.ethz.ch/natureofwood/pc/st/st5.html

Knots and holes do affect the strength of a joist but the three most important factors are: the dimensions of the lumber, the location of the hole, and the size of the hole. Best-case scenario is that you have a hole just big enough for the purpose needed, directly in the center of the joist. Worst-case scenario is that you have a hole that is too large and is located at the bottom of the beam (the tension face). As the article points out, a 1/2 inch hole in the tension face of a 2x10 joist can reduce the bending strength of the joist by as much as 9 percent!

How do I repair a floor joist which has a hole drilled less than 2 inches from the bottom?
I've been experiencing a little bit of system instability, so right now I'm going about limiting my CPU and RAM usage within Windows to see if I can pinpoint anything. I've found how to limit CPU usage in Windows' power options, and it appears as if the old MS config Window has a place where you can limit the allowance of RAM that Windows has access to:


I have 8 GB of RAM installed and I'd like to limit it to 7. My question is, what happens to the excess 1 GB of RAM? Nothing at all? I have a dedicated video card and video RAM, will it affect that at all? Will this effectively guarantee that I never use more than 87.5% of my total RAM in Windows?

Overall, I guess what I'm asking is if this would be any sort of effective strategy to increasing system stability, or would it just make it more complicated? I am using Windows 8.1 (64-bit).
