    Mike, first I'm going after the explanation for "modding", then I'll go to ATI and get the CCC (I'm curious to see what the functions of the Catalyst are), then I'll post my rating. So far you've been very helpful, so I'd appreciate it a lot, look for my next post after I try this fix, and wish me luck!

    My notebook model is PD726AV#ABA, HP Pavilion zd8000, but there's also one thing I forgot to ask you yesterday. In your original note you say that you used two steps, the first one was using ASO or Advanced System Optimizer, and that the purpose was to force the system to write the swap to memory instead of the HDD, but in the modder you changed the graphics memory to 128MB from the original 256MB. My graphics memory is also 256MB, but I don't understand why you reduce it?

    I don't have ASO, so it really doesn't matter but I'm still curious of why reducing it to 128?

Hi eltrury,
Here is a link to explain Modding.
You're notebook share's you're main system memory with you're onboard (Video card built into you're notebook's main board).
If you're notebook has a total amount of system memory of 512MB & you're video card is using 128MB to function. Than you're notebook will only have 128MB to run. (And that is not enough for a Windows XP system to function. It will run! Like a dog with two broken legs. You're video card is an ATI. That said, ATI comes out with newer versions of its software drivers quiet often. So upgrading you're software can be preformed once a month, if you like. ATI's catalyst control center is part of the ATI's software. CCC is a section of software where you can adjust a range of settings to you're preference. Like add more red color to your monitor. Adjust you're display screen. It's a long list. There is a Help button within CCC.
Most people never need to enter CCC. It's for people who know what to adjust & why. CCC's greatest function allows people to run dual monitors. CCC can detect when two monitors are connected to the video card & the user can adjust the color for each display separately. CCC is also acts like a software manager. It helps keep the video running stable. For those who do not have an abundence of hard drive space you can elect not to install CCC & just download the driver software.
This next link will take you to ATI's web site.
Here you need to click on three choices. In the first window you would click on you're operating system. EX: Windows XP home or pro. Than you would click on ATI Mobility Radeon. Than click on, Mobility Radeon X600. Lastly, click on the GO button.
Suggest you run the Installation Verification Software on the site. When it finishes the ATI software should start the download.

If I can help you further, feel free to post.
Suggestions & comments welcomed.

    I forgot to tell you how to adjust the amount of video memory. To do this enter you're bios menu. Go to the title Advanced.

    There are a bunch of settings within Advanced. (Tough suggesting such adjustments not knowing the notebook model.)

    One of the settings will allow you to change the total memory used by the X600. Save & exit.

    Hello again Jess,

    You ask me how to reduce you're video memory from 256 to 128!

    This was stated in you're question to me. You can read this at the top of this post.

    I never mentioned or posted this statment: ( "In your original note you say that you used two steps, the first one was using ASO or Advanced System Optimizer, and that the purpose was to force the system to write the swap to memory instead of the HDD" )!

    You can read what I posted driectly under my picture above.

    To download drivers for you're HP Pavilion zd8000 CTO Notebook PC. Click on this link.

    On another note. In my experiance, any notebook that use's 512MB of memory will run slower than a notebook with 1GB of system memory. Every notebook share's their system memory with their onboard (intergrated) video card. The video card use's the notebooks system memory to function. That video memory can be adjusted to use 32,64 & 128MB of memory to run. The more system memory a video card uses the less the notebook has to run the operating system & programs.

ATI radeon x600 128 mb video (Windows 7) driver

AMD's DirectX 9 ATI Radeon graphics accelerators are not officially supported under Windows 7. But you can install ATI Catalyst Windows Vista graphics driver under Windows 7. Some features may not be available under windows 7 but it would be worth a try.

I need to download ATI Display drivers for my Toshiba tecra S211 but i m not getting it on the net

ATI uses drivers called Catalyst Drivers. The ATI card you have is the ATI Mobility Radeon X600. Go to this link;

Select your Vista or XP or whatever your Operating System is from the first list. Then in the second list, select mobiltiy radeon. Then Mobility Radeon X600 from the third list. Then click GO.

Then on the next page use the installation verification software. Once it verifys your hardware is compatible with the driver, it should download and install it.

Try restarting the pc in safe mode by tapping the F8 key while re-booting the computer. If the lines are gone it is the display driver.

ATI Radeon IGP 340mM/345M display driver or software needed..

Go here:
ATI Catalyst 8.2 - ATI Radeon - XP

Then, near the bottom of the page, click on:
Individual driver download packages, ATI Multimedia Center, Avivo™, and Korean full package and download the Catalyst Control Centre package (download 2 of 3)

Here is a direct link, but i don't know if it will re-main active:
AMD GAME! Drivers and Utilities
Then click on "Catalyst Control Center (English)"

This package will only install the ATi CCC. I personally have found that the ATI CCC doesn't like older cards, but some people have had luck getting it to work. If it doesn't work, you'll either have to find an older Catalyst Control Center, such as the one bundled with the Catalyst 4.10, or go back to using an old version of ATi Catalyst Control Panel.

ATI Mobility Radeon X600 (PCI Express?), in an HP Pavilion zd8000 Notebook.

The Deadlock Bug Finally Solved

I had the same problem for a year or so. I used vista in the meanwhile, but after a 3D bug I got upset and decided to try fix this bug, finally succeded in it. I'm sure it has something to do with the memory, but still there's a mistery........

The solution :
It can be a little wierd, the softwares i used are : ASO - Advanced System Optimizer 2.2 and Mobility Modder 1.0 Final.

Step 1 (ASO) : In the windows optimizer at the
System Performance #2 I turned on the :
Improve Core Kernael Performance
Enable Large System Cache
(I made the cache size 1,024 - not sure if this was necessary)
Theese options were to force the system to write the swap on memory instead of your HDD

Step 2 (Mobility modder) : First download a new Catalist Driver from anywhere on the net, then the modder from :

This software is quite handy because you can use the latest catalyst on your mobility radeon.
After The modding I've set the Graphics memory on 128MB -from (it was 256 earlier) -

The only thing left for you now is to install the newly modded catalyst and enyoy the advancements of your 3D card again.

Not sure if step 1 is necessary, but my problem was solved after step 2, so my 3D card was back form the DeadLock and Infinite loops, and finally running smoothly on XP again.

Btw I have a HP zd8000 with x600 mobility.
