That baking Manchester sun is warping your brain, Tyla. Still celebrating the Reds' double a little too hard? (Oh wait - I just remembered all us United supporters live in London

)
Cough.
Anyway - you think you might have removed the sound card, but it's still listed in Device Manager - is that what you're saying? If that is the case, uninstall those drivers via Device Manager to start with.
Next step, reboot your PC to access the BIOS. There should be an option somewhere for integrated peripherals, one of which will hopefully be on-board sound (AC97 or somesuch). Enable it if it is there, otherwise come back again for more help.
Post the name/model of your PC too - we can google it, even if it's ancient.
