Windows 7: Lost Sound after Power Shortage

Lost Sound after Power Shortage

Hi everyone, I forgot my laptop in sleep mode yesterday, and since my battery is dead, someone from the house removed the AC Adapter and the PC turned off, when i turned it on this morning, there was no sound, there is no red cross on the sound icon in the notification bar, that one is fully functional as i can increase/decrease volume, but there is no sound coming of the speakers, i tried with my headphones, but still nothing, I've checked my Control Panel and the speakers are already set to default, but nothing comes out, i also tried uninstalling and reinstalling the drivers, and the problem persists, i rebooted 7 times to no avail, can anyone help me on this matter ? I did however find a temporary fix, going to the bios and "Save settings then Exit" seems to get the sound back but, every time i shut my computer down completely, the sound is lost and i have to do the fix again.

I use a Intel Core i3 M380 DELL INSPIRON N5010 running Windows 7 ultimate x64 bits on 4GB of ram, Intel HD Graphics 2000, my Sound Card uses IDT High Definition Audio Codec that i got from Dell's Website. If you guys need any more info please let me know I'll be monitoring this thread by the second.

A power failure (what you had) can cause untold damage, from just a corrupted OS/hard drive to actual hardware failures.

There should be Dell diagnostics installed on the hard drive (I think accessed by F12 at power on), run the hardware diagnostics as a first step.

If the hardware diagnostics pass, the next step is to use the System Restore function and restore the PC back to an available restore date that is PRIOR to the power failure issue. System Restore can be accessed from Start/Programs/Accessories/System Tools. System Restore will not delete any user data.

If that does not fix it, unfortunately the next step is to use the Dell PC Restore (accessed by F8 at power on) and restore the PC to the original factory setup.
