No sound Dell Inspiron - Windows updates? ERUNT? antimalware

by deltaskye - 10/14/13 7:19 AM

Several weeks ago my laptop stopped producing sound. I have investigated multiple options and am wondering if there have been any recent known bugs in lost sound, due to upgrades or something else that caused problems for others. I have tried the following:

- double-checking all the keyboard "F" function keys
- using Dell's trouble-shooting tools and instructions, which tell me the sound components are in good order
- updating drivers/removing and re-installing drivers
- using Windows' and control panel's trouble-shooting tools
- Using Microsoft's trouble-shooting tools
- altering the sound "theme" offered by Windows
- adjusted the volume settings on my laptop

My laptop has IDT High Definition Audio CODEC as the default sound device. I don't use plug-in speakers or headphones.

I haven't dropped, jarred or otherwise damaged the laptop.

However, over the past several weeks I have:

- installed ERUNT as an emergency recovery utility; I received error messages when I logged on, so I removed it
- installed suggested Windows updates
- installed MS Office updates
- regularly run Spybot and Spyhunter in addition to Malwarebytes

I noticed that my browser is slow and often locking up. I have to go into the Task Manager to get things moving again. I wonder if this is caused by script problems - Java, Shockwave? Could one of these be affecting my sound?

A poster on another forum recommended I do a system restore. I've never done this and worry I could lose something valuable or cause worse problems.

I am running Windows 7 Home Edition on a Dell Inspiron N5010.

Thanks in advance for any assistance. It's driving me crazy not to have any sound.
