What I could understand from your question is that your Driver softwares are not installed in your system.
Go to this site and click on 'Download drivers and software'
You will now get an option 'Select Operating System'. Click on the OS that you have installed in dc7700
Now download the following drivers Driver - Audio Driver - Chipset Driver - Graphics Driver - Modem Driver - Network
and install the same on your dc 7700. Now you will be able to play sound and also browse internet after you configure the LAN (TCP/IP) properties.

HELP!! My New Probook 4530s Notebook, Audio & Video Glitches n Hangs Making Annoying

OFFICIALLY ()? fixya is never ever OFFICIAL, only at is.
  1. sure get it fixed
  2. or learn how your self?
since you are here and not at my guess.
is you cant get it fixed? (in PC repair shop)

why not just tell what you do exactly and then the bad effects.
what audio are you playing,???
files (like MP3)
windows sounds.
what video's we cant guess this nor the formats (100s)
is it store bought DVD>?
is it a video filie
is it online video streaming like netflix or youtube.
what? we can not know what you are doing unless stated. clearly.

why not do simple things first
like playing MP3 file using windows, media player.
get any MP3, play it,

more simple.?
does the CP control, selected SOUND ) (CP = control panel)
then tab to SOUNDS
then click default beep, and test.?
sound ok? repeat 10 times, ok now.
if not make sure there is only one sound chip in system
not 2, like inside chip inside pc, and one outside say USB headphones. unplug all USB devices, sounds work now.?

look is CP+ DM device manger, for sound chips with errors.

down grading the HP software was a bad move.
sorry. why not use the corrrect drivers off
why not?
or even reload the OS.
using HP way.

there can be many CAUSES OF failed sounds, buzzzzz
ill not go to video, due to sounds bad , is first.
did you try using ear buds in the speaker phone jack to see if the buds sound ok>? (as opposed to the speakers )

1: not using HP drivers from
2: virus infected.
3: sound chips bad, (very very rare)
4: kids stuck sharp objects into speakers, wrecking them, try buds yet?
5: windows 7 corrupted, run "SFC scannow"?
6: 2 sound chips trying both both run same time (with head phones uSB)
7: PC is overeloaded, and running so slow it cant run sound correctly by having too many startup fails running, clean them out.

your tech can do this, step by step.... let him?/her?

My com has best defence against online threats, so i can't access internet, i tried basic connection like reset but it didn't work.. I couldn't make Lan network connection eather.. what...

Are you still having this problem? If so, uninstall Norton 360 and restart the system.
After restarting then setup Norton 360 do not add any additional apps into your computer until
it fully is installed and it tells you to restart the system.

If that doesn't solve the problem then get AVG Internet Security 2011 and it will help you to secure your system from hackers and viruses.

Let me know if the problem persists. Then the other thing is total format of the system and all data has to be backed up in Safe Mode. Do not do any thing other then backing up and formatting the system to a fully brand new partition and install Windows back on and do not connect to the internet till you get Norton or AVG installed once there installed then connect to the internet and see if that solved the problem.

After that install on the applications and then restart and login into your system and your all set.

Sound problem

This is fairly common after installing new hardware or software.

There are several easy fixes, but the one that works best is to:

Uninstall your Sound devices, reboot, and your system will automatically reload them either from your System drivers or from the Internet/Microsoft.

There are many other simple ways, but this has the highest positive results and usually removes problems and reverts back to the working defaults.

Hp dc7700

verify you device manager if there is modem or network card installed, if you see a device with yellow question means you need to install the right driver

network card are built in to motherboard...maybe the right driver is not installed.

you can verify the original configuration by going to hp web site support and type the product number..

My Hp pavilion tx2000 cant play audio files,cant connect to net

Hi James

First, Sound drivers:
HP Pavilion tx2000 CTO Notebook Realtek High-Definition Audio Driver A from HP notebook

and video drivers..
HP Pavilion tx2000z CTO Notebook NVIDIA GeForce Go 6150 Video Driver A

Now network:
HP Pavilion tx2000 CTO Notebook NVIDIA nForce Chipset/Network Driver 5.53 A

and wireless!
This is an older WIFI driver that only works in XP, and in certain HP Pavilions, but try it.

and this is the Vista one that is correct for your laptop, it probably doesn't work in XP but if all else fails, you could try it. (You should really run Vista on it, I reckon)-----------------
HP Pavilion tx2000 CTO Notebook Broadcom Wireless LAN Driver 7.0 Windows Vista

All support you need is here at HP Tech Support:

Good Luck

Merry Christmas
