Hi,

I had a USB power surge about 2 weeks ago, tried resetting it to no avail. I restarted the Laptop and now USB and sound are gone. I've gone as far as reinstalling the whole pc. Everything. From Bios to Windows.

Still nothing. I'm guessing my motheboard got messed up. If not, what else could it be?

Both USB and audio are likely controlled by the south bridge chipset. So when the USB surge damaged that chip the audio was affected too.

The only other thing might be that audio drivers need to be installed. I doubt that's it since the problem began with the surge but check in device manager and see what, if anything it says about the audio hardware. You may need to go to Dell's support page for your model and download those drivers.

Thanks,

I forgot to mention that. The whole sound device disappeared from Device manager. The USB still shows there. I installed the whole system over which included all the drivers. The guy who did this (He orginally sold me the laptop) Said he hadn't heard off a USB Power Surge.

I've also uninstall the USB from DM and rebooted. It reinstalls, but no function.

Thanks!

I assume anything related to the audio has been enabled in cmos/bios setup?

If it is the southbridge chip, or a separate audio chip for that matter, I doubt if it's practical to repair it. It'd probably be cheaper to replace the motherboard, but with a laptop that's going to be hard to do by yourself unless you have previous experience.
