code 39

hi,

i been running windows vista for about 6 months now without any serious problem but lately it has developed a problem with recognizing the graphics card drivers,
in the device mangaer i get the message, code 39 windows was unable to load the drivers for this device or the drivers are corrupted.

If i uninstall the drivers i have trouble rebooting, and get messages saying i should repair windows that the driver kernal is corrupted, or winload.exe is corrupted, and then it boots up very slowly, maybe 20 mins to start. and then randomly after a few restarts itll work fine again, but then the problem will come back again after another start up and it will lose the drivers again.

when i first had this problem i tried a fresh install, and the system worked fine for maybe 3 days but now the problem has returned.

any assistance would be greatly appreciated

Try running chkdsk on your harddrive.
Run a memory checker.
look at your error logs;

Left Click on Start Menu.
Right click on Computer and choose manage.
Click on the event viewer.
You now have loads of options to try and pin down what is happening.
Expand the error tab.
Look for things in the last 24 hours.

Also look at your reliability and performance option.

Let us know what you found and we will start looking from there.

I don't really knw if this will work but u can give it a shot.. after a fresh install install the your graphics drivers form the cd provided with the card.. then update them using windows update n not the company site.. give it a shot n lemme know if it helps..

Hi,

thanks for your responses, the system seems to have become more stable by itself, all i have done is turn of dream scenes, but i havent had the chance to test the gfx card doing anything taxing yet.

ok so the chkdsk reports all ok, am going to start memory testing soon,

i have found a kernel-general event id 5 error which seems to be the most relevant to my problem, ill copy the details below

general tab description

{Registry Hive Recovered} Registry hive (file): 'SOFTWARE' was corrupted and it has been recovered. Some data might have been lost.

and in the details tab i get this

I am already using the windows recommended drivers for the gfx card,

is there any kind of diagnostic tool i can run on my gfx card like a memtest, to isolate whether its a hardware problem, i googled it but couldnt find anything for vista

again thanks for all your help
