I have a windows xp computer and about a month ago my computer would no longer play sound and in the control panel everything was grayed out. Im pretty sure my soundcard is built in, in a chipset. I also remember installing malwarebytes to try to clean up my computer and I remember it sayin it deleted a trojan in system volume restore or somethin like that. I system restored to a bunch of points and that didnt work. I checked the BIOS and everything is normal. I've tried to install many audio driivers.I've gone to the device manager and I dont know if my sound driver is even there anymore nor do I know what it was. Please help, trust me I've googled this topic for at least a month with no avail.
