got a problem were the pc stopped playing sounds, any sounds at all. It just stopped while playing music. everything seems to check out on the pc side.

What ive done:-

Removed the sound cards and reinstalled them.
Restored to a earlier point.
Tried a head set.
Tried a new sound jack cable.
Tried new speekers
Ran a program from microsoft to check for problems http://support.microsoft.com/gp/no_s...ntrypoint=WHHT
Threatened it with a hammer.

Anything else ive missed that i could try??
