[apfcmpsb]

I formatted my c: drive, installed windows 7 recently and after that i have got two problems...

1. All my speakers including laptop speaker and headphones are producing heavy distortion.

2. Network tray icon is showing red cross sign though internet is connected and browsers are working normally yet Updates are not working(showing no internet connection for example bitdefender update, dell support centre updates, etc..).

Actually i am using dell inspiron n4030 and and bitdefender total protection 2012
I have tried all optimizers tuneup utility, regcure pro, and all that given in this forum nothing solved my problem....PLEASE HELP ME OUT.......?????

First off,

How did you format your C: drive?

I recommend using this method:

SSD / HDD : Optimize for Windows Reinstallation

Secondly. Have you tried manually installing all the drivers? From what I am understanding, you are unable to do a windows update?

Yes I have manually installed all the drivers from the cd provided along with my laptop
but problem was still there


And ya windows update is showing "no internet connection".

I have formatted normally using a Bootable dvd....

Well on the distortion problem, that seems like to me it would be a hardware problem.

Have you tried to use a Ethernet cable and hardwire to the internet?

Hello apfcmpsb. Welcome to the forum.

Some more information about your system and problem would be helpful. Please fill out your system specs under your Sevenforums profile.

Also would help if you could describe what your Device Manager looks like. Any yellow ! or red X's? You can post a screenshot of the Disk Management window also.

What was installed on the laptop previously? Was it W7 or was it Vista or XP?

The drivers on the laptop CD are usually old and keyed to the original operating system. If you are installing W7 for the first time on this laptop then you will need to find and download the most current drivers for your machine that are made for W7. And you need to get the drivers that are for the 32 bit or 64 bit version of the operating system, depending on the version of W7 you installed.

Installing the wrong version of the drivers can cause problems such as yours.
