Hey Guys.....

Looking for some help.

My main machine for crunching has recently started having some issues with my dual 750 video cards.

I am getting an error in the Boinc management console saying "Unable to intialise CUDA device"

I am also getting computation errors on seti only work units.

I have recently done a fresh install of Win7 XP 64bit and have used the latest GeForce drivers and installed the basic installation with the drivers which only install the driver and the PhysX driver.

To get Seti crunching again requires a computer restart. The cards arent overclocked.

I have done all the usual things including cleaning the cards to ensure they arent overheating and their is plenty of airflow over the cards.

So if anyone has any ideas before I go and replace the cards that would be appreciated.

Everything I can find suggest it's a driver issue.

I'd suggest trying 344.11 as that's what I was running on my system when it had Win7 on it with no issues at all (or at least something not so recent, say 358.91).
And i'd go for a clean installation, selecting just the driver (you only need PhysX for games).

Thanks for that Grant...

I was thinking about rolling back to an older driver.

I am in the process of downloading the 344 and 358 drivers and will try them both and see what happens.

Just an update on this. I rolled back to an older driver but was still getting crashes so I started looking at the log files and as soon as I stopped processing the V7 work units the machine has stopped crashing.

So I am going to go back to a newer driver and see what happens.

You're not trying to use Windows Remote Access to remotely view that PC are you?

If you are then that would account for those errors that you're getting.

Windows Remote Access uses a generic video driver once it's in use it's there until you do a restart.

Cheers.
