WTF is going on here? I have uninstalled Half-Life 2, Synergy, even Steam itself. Synergy doesn't work under the Cody user account, but it does work under the Luke user account. So in other words, there are 2 user accounts on his computer. I'm referring to the actual Windows user account.
Incredulously, I have found that if I log into my Windows 7 user account on his computer and try running Synergy, it works! And to be clear, Steam is still logging into his account. I checked task manager, and hl2.exe isn't running or anything like that. The problem is that whenever he tries to run a Half-Life 2 mod called Synergy (a co-op mod), the screen flashes white and then nothing happens. I installed all of the most-recent drivers, and everything seems to be working great.

Here's the story: I built my brother a brand new computer.
