There a number of problems that you might encounter on your workstation. This page is an attempt to catalog the most commonly encountered problems, and fixes as they are found.
This list is by no means exhaustive, and may not contain a solution for every problem.
Windows
-Mouse and Keyboard Not Working?
--This can happen pretty frequently, especially if you start building new workstations. Most of us use wireless USB keyboards, and newer motherboards have options in their BIOS to enable/disable drivers for USB 3.0 ports. If these options exist, you'll generally want XHCI Hand-off enabled, and EHCI hand-off DISABLED. This is particularly relevant if the keyboard and mouse work in the BIOS and GRUB but not in Windows.

Linux
Updates not working Correctly? Check your sources list. Some of us are running Debian 7 (wheezy) and some are on Debian 8 (Jessie). If you notice that updates are not working, or dependencies can't be resolved because of broken packages, it could very likely be your sources list. An excellent discussion can be found on the debian website. Link: https://wiki.debian.org/SourcesList
