Hi. Currently I am experiencing very slow video playback on all kinds of
videos, home movies, n online tv shows. I have done several troubleshooters
and it appears I have a video card whos driver may not be functioning
properly. It is a REALmagic video card, however repeated searches have
yeilded me no proper drivers to reinstall. And driver programs report the
current driver is up to date. Is there a "generic" video driver i can use?
I have an older system with a pentium !!! processor using XP professional.
Has the system ever worked to your satisfaction in the past? If yes,
what do you think changed since then?
Do not rely on any driver programs - rely on yourself. Use Device
Manager to figure out what video driver you are using, then go to the
manufacturers WWW site to see if there is a later version:
To launch the Device Manger console, click Start, Run and in the box
enter:
%SystemRoot%\system32\devmgmt.msc
Are there any yellow ?s in the display and if so, where?
Click OK, expand the Display adapters section, right click your
device, Properties, check the Driver tab to see what your driver
version is and check to see if there is an update.
Reduce the number of questions, any further guessing and and trying
things that might work maybe by supplying more information:
Click Start, Run and in the box enter:
msinfo32
Click OK, and when the System Summary info appears, click Edit, Select
All, Copy and then paste back here.
There would be some personal information (like System Name and User
Name) or whatever appears to be only your business that you can delete
from the paste.
Reduce the chances of malicious software by running some scans.
Download, install, update and do a full scan with these free malware
detection programs
then resolve any remaining issues:
Malwarebytes (MBAM):

SUPERAntiSpyware: (SAS):

These can be uninstalled later if desired.
If you are using IDE drives, use Device Manager to verify the transfer
mode of the IDE channels is set to some kind of DMA mode (usually DMA
if available - depends on your hardware) and not the slower PIO
mode.
PIO is the slowest, DMA is the fastest.
This is easy to check and generally easy to fix and the mode would not
have changed by itself, so if it has changed to PIO, change it to DMA
and then figure out why it changed and fix it.
To launch the Device Manger console, click Start, Run and in the box
enter:
%SystemRoot%\system32\devmgmt.msc
Click OK.
Expand the IDE/ATA controller section to see your IDE channels. Right
click each, choose Properties, and for each channel that has an
Advanced Settings tab, determine the Transfer Mode. There are usually
4 channels to check in a desktop, maybe fewer for laptops.
The fastest selection will be some DMA selection (usually: DMA if
available). If it is PIO, change it to DMA.
If you are not sure about what you see post back for help and advice.
Follow this up with a reboot to make sure any changes stick.
What may have caused the change?
