well since i installed the New sound card the system doesnt crash anymore, it just doesnt produce any sound.
I checked bios and it assigns the IRQs automatically. I tried manually assigning one, and i still didnt have anysound.
Nothing on the system is muted and the speakers are connected correctly.
Did sound work out of game? Or was it just loading up a game that would crash the computer/ not produce any sound?
Try uninstalling everything
sound cards. You may have some drivers still installed and allocating resources to a card that isn't there.
This is a strange case, but it sounds like physical failure of a device (obviously not sound card since the new one doesn't work, either) as opposed to misconfiguration.
If you have other computers at your disposal try testing the sound cards just to make sure they work. Hope you have some luck.
