Jerky graphics

[JSPIPE]

I have a problem with jerky motion that i would describe as ' 2steps forward
1 step back'.
It can affect a single object moving against a static background or the full
screen picture
in both vertical and horizontal motion.
Anything more than gentle motion is jerky.

For example: a race car approaching a corner, perspective means low speed
down
the screen and the car is in clear focus then, as the car turns into the
corner, it
immediately becomes a blur as this '2 steps forward 1 step back' motion
kicks in.
If the camera follows the car round the corner the car can remain clear and
the
background become jerky.

The picture quality is good apart from this jerky motion.

This problem first appeared in games, but has now become so
bad it affects USB tv and internet streaming as well.


It appears with different monitors.
It appears with both on-board graphics and PCIe card.

Changing screen resolution and refresh rate has no effect.
I have tried different FSB rates between 200 and 250 Mhz,
setting RAM/FSB to 1:1, both MIPS options and PCI latency settings.

I have run Prime95 in the background when the CPU temp rose from
less than 40c to above 60c.

Installing SP3 and the 2008 Dx update made no change.
The DX diag tests run correctly.

Nothing that i have done makes any difference to this condition.

All this time the computer has been stable with no freezing or errors.


Help needed.

Thanks

================
Three possibles...

Do some maintenance: Disk Cleanup,
Error Checking, Defrag...

Upgrade your video driver.

Install more RAM.

I have had this problem for several weeks and i have covered all those.

IE clears the cache at closure so there is only ever a few KB to cleanup.
I have run error checking at startup and defragged.
I have re-installed the latest driver from Intel for the 945G
integrated graphics.
I have tried all the ATI drivers from 8.2 to 8.5 (with and without the CC)
for the ATI 1650 pro PCIe card.
I have 2GB of PC6400 RAM.

I have run SFC and then gone to Windows update, but there was
nothing unexpected so i assume the Windows installation is good.
I have always kept Windows up-to-date.
I have changed the page file from custom to system controlled.
C:\ is 14.6GB with 5.2GB free and with 2GB of RAM i guess
the page file doesn't get used much.

I have re-installed the games and the USB tv software and have
a fresh installation of the BBC iplayer.

I have run it at 200MHz and just the USB tv when the CPU
was at just under 40c and the system at just over 30c.
I have run it at 250MHz with the USB tv and Prime95 when
the CPU was at 60+c and the system at ~ 53c without
any lockups or crashes or errors in Prime95.
If there was a fault on the motherboard i would have thought that
would reveal it.

I have just about run out if ideas.

===================================
Sounds like you have covered everything....but
I think I would consider a larger partition for C:\
and I would still run Disk Cleanup or use a freebie
like CCleaner. There may be more .tmp files than
you expect and closing IE may not eliminate all
of them.

It also may be worth a try to reduce your Graphics
Hardware Acceleration:

Another possible location for memory
hogging temp files is explained in the
following tutorial from Yves Alarie:

Files downloaded from the internet or e-mail
may be in a subfolder of your Temporary
Internet Files folder.

The folder name will start with OLK and
there will be a number after OLK. The easiest
way to find this folder is to search for OLK*
and once found open it and see if the files
are there.

Click on Start and Search and then:
All files and folders
More advanced options
Search system folders
Search hidden files and folders
Search subfolders

In the top textbox "All or part..."
type in exactly this OLK*
and click search

This search will take a while but should
return all folders starting with OLK.

Open the folders, select the files and delete.
They will go to your Recycle bin, delete them
from there also. Or, hold the Shift key down
when you delete them in order to prevent them
from going into your Recycle bin.

I tried reducing the Graphics acceleration, but that didn't
stop this jerky motion even at position 3 when the tv
vision had ceased and the game picture had lost its fine
detail.

I installed a game on the other computer and even with Win 98
and a PCI graphics card it was clear that these jerky movements
were not there on either monitor.

I couldn't find any OLK.* files.

I've had trouble using disc cleaners so i no longer use them.
I did a search for .tmp files and found 17.3MB.
Even if i was able to find all the superflouous, redundant and
duplicated files i would probably gain just a few MB of disc space
but i would risk damaging the system.
I found a program called Sequoiaview that revealed a 2GB
Memory.DMP file, which i have removed.

So i now have a computer with 7GB of free space on the C:\
partion and jerky graphics.

Can you think of anything else, i'm stumped.

=================================
I'm running out of ideas.

Have you tried doing a System Restore to
a time before the issue began?

Maybe you have a compatibility issue with
some of your software. Sometimes virus
scanners can cause issues.

I've been using Avast free version and Windows defender for years.

I'll try system restore.

Thanks for all your help.

Try setting up the computer with as few background programs and services as
possible.
IE
No internet or network connection and the associated software support,
including such things as zone alarm, antivirus, UP&P, etc.
As few devices as possible should be connected to the computer.
Eliminate any non necessary "services" .

In the process, task manager will likely be quite useful.
