Realtek Hgh Definition problem

Hi, I have a serious problem. I have an Acer aspire 5570z laptop and one day i realised i had no audio. I have done everything i could and need some serious help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

It would be greatly appreciated.

 

Here are some specifics :

Operating System: Windows Vista™ Home Premium (6.0, Build 6001) Service Pack 1 (6001.vistasp1_gdr.080917-1612)
Language: English (Regional Setting: English)
System Manufacturer: Acer, inc.
System Model: Aspire 5570Z
BIOS: ZR1 v1.3505 3E05
Processor: Genuine Intel(R) CPU T2080 @ 1.73GHz (2 CPUs), ~1.7GHz

 

EVERYTHING?!?!?! Wow! That's a lot of stuff!! LOL Just kidding. Without some details of what it you've done, all I can suggest is to uninstall the driver, reboot, install your chipset drivers, reboot, and install the audio drivers. You might try a system restore to a date when you can remember the sound working before you re-install the drivers. You can find all your drivers at the Acer Support Page.

 

Very funny, i checked but i am not seeing any download for chipset or audio drivers
