After your computer crashes, is it blue screening or are you simply receiving a black screen followed by your BIOS boot up screen? Since it's also happening on DoDS, we can reasonably assume it's not just the CS:S files that were/are borked but also the Source engine files. In that case, here's what you need to do.
Uninstall ALL Source based Steam games (based on your description, this should only include CS:S and DoDS) from the Steam interface. After that, navigate back to C:\Program Files (x86)\Steam\steamapps. Inside of this folder, you should see several files with a GCF extension - multiplayer ob binaries.gcf, source 2007 shared materials.gcf, source models.gcf, etc. - delete all of them.
When you go to download CS:S again, these files will be re-downloaded and recreated. If there's something wrong with one of your Source core files, this could be the problem and redownloading them should resolve it.
Let me know if it still continues to crash. It very well may, in which case we'll start attacking your drivers and hardware next.
