Normally using my laptop last night. When i opened it this morning. I have no sound and the deadly X red mark on my volume on my lower right screen is present.

It is obvious that this problem (no audio output device installed) is very common to many. Reading through hundreds of threads saying i just have to find "sound, video game controller" and re install it. The problem with mine is that i dont even have that kind of tab on my device manager? how come?

(By the way...when i open my Device manager. I can see under Other devices that i have 3 Base System Device that has a yellow exclamation marks on it) FYI

I tried looking for sound programs in my computer (through search, through dxdiag, etc.) and i cant even find a sound driver. Because of this, i go to Realtek and installed the newest high definition audio codecs for 64bit windows 7 which version is R2.71 update 2013/4/8. Feeling confident that i can now install it to my device manager...i tried doing it. To no avail, i cant install it...this is the procedure that i am doing...

1. Device manager
2. Add legacy hardware
3. Next>choose Install the hardware that i manually select from a list. Next
4. Choose Sound, video and game controllers
5. choose Realtek. Next, Next
6. THEN...after will say...."An error occurred during the installation of the device. The extended attributes are inconsistent" FINISH

I really dont know what to do about this. If anyone can kindly help me, i would greatly appreciate it. I am not very good with computer terms so do bear with me.
