1622 Views 20 Replies 4 Participants Last post by  Cookiegal
hi all,

my pc is running really slow. it gets stuck whenever a new program is launched. have video and audio stuttering. and have had to delete all games.

i have a desktop running windows xp. after much troubleshooting and searching online forums, i am trying this as the last recourse.

i have an unknown device under sound, video and game controllers. the device instance id is root\media\006.

there are no drivers installed for this device.

i had nvidia video card which i have removed. have also removed the modem card.

any help would be really appreciated.

thanks in advance.

You appear to have a HP/Compaq brand computer with a very outdated version of Windows XP Professional.

What's the model name and model number of that computer?

What's the part/product number on it?

my comp is compaq presario SR5160IL.

the unknown device has a device instance id as 'ROOT\MEDIA\0006.

the unknown device is under 'sound, video and game controllers'

my 2 bits of knowledge - had logitech rumblepad installed which is now removed, but it still works when i connect to the comp. could the driver for logitech have taken over my system device?

have service pack 3 but have changed the cds key through regedit to 200. this makes my machine really fast.

also removed malware on the comp.
sorry, meant 'had logitech rumblepad installed which is now removed, ...'

Here is the support site for the Compaq Presario SR5160IL (GG003AA) desktop.

It was introduced in May 2007 and sold in India.

It came with Free DOS and did not come with any Windows operating system.

It lists full driver support only for Windows Vista 32-bit for these primary devices:

Intel 82945GC (Intel GMA 950) graphics

Realtek ALC888 high definition audio

Realtek RTL8201E 10/100 Mbps ethernet

It came with only 512 MB of RAM, but you appear to have maxed it out with 2 GB(2048 MB) of RAM. :up:

It came with a 160 GB SATA hard drive, but you appear to have replaced it with a larger capacity one and set it up in H, I, J partitions.


Please do the following:

Download MGADiag and save it to your desktop.

Double-click on MGADiag.exe to launch the program.

Click "Continue".

Ensure that the "Windows" tab is selected (it should be by default).

Click the "Copy" button, then leave the MGADiag window open.

Return here, then paste the log in your next reply.

The bottom part of the MGADiag log appears to be missing.

I've requested a qualified person to examine the log that you've submitted.

There's an older installation of Office that's not genuine so you should uninstall it.

Microsoft Office Professional Edition 2003 - 114 Blocked VLK 2

As for the OS please explain this statement further:

"have changed the cds key through regedit to 200"
have service pack 3 but have changed the cds key through regedit to 200. this makes my machine really fast.

There's an old registry hack that makes Windows XP believe it's running SP3 when it's actually running SP2.

The value of 200 is for SP2.

The value of 300 is for SP3.

I don't remember what registry key it's done in.

It's probably the registry hack shown here :-

If that is the right thing I don't see why it would speed up a computer though.
I switched to sp2 through the regedit (it just makes the comp believe it's sp2) to get the audio working again.

chanced upon the machine becoming faster when I had switched.

One more thing, I can't uninstall this device as it says it is required for booting the system. also, it has no drivers installed
Since it's a System Builder's license feel free to continue if someone can help. But I would reformat and reinstall with SP3 and all subsequent updates. Then, if there's still a problem with audio I would troubleshoot that rather than using registry hacks that may cause other problems.
My install guide in the "Windows XP" section may be helpful to you.

Thanks to both of you for your help and suggestions. I will try and reinstall xp.
Thanks once again Frank and Cookiegal. The comp is working superb after xp reinstall. and yes, did check the install guide in the xp section.
