I decided to download the newest version of the k-lite codec pack since I had a video file that I couldn't watch on my laptop. I decided to go ahead and download and install in on my desktop(the computer I'm having the problem with) as well. I uninstalled the previous version with no problem. I installed the new version and also had no problems. When I watched a .flv file with media player classic, I noticed there was no sound, so I went into the sound options to adjust some things. Then all of a sudden my computer restarted automatically and I got a message saying something about recovering from a serious error. I went to the event viewer to get more information, but the info and links I was given didn't seem to pertain to my situation directly. One thing mentioned was the error might happen when using diagnostic programs, though it only mentioned things such as regedit. Also, it mentioned it could be related to the sdbot and haxdoor viruses, though I doubt that since I downloaded k-lite from free-codecs.com and my system is clean( I just scanned yesterday). So, is my problem related to media player classic and the k-lite codec pack? I'm using the Full version of the codec pack, FYI.
