I just updated my Boinc client from 6.12.26 to 6.12.33. The .26 version was working fine with my Nvidia GS450 video card running Einstein and SETI tasks just fine.

The new boinc tell me it can't find a GPU. According to Nvidia I have the lastest deivers:


Product Current Latest Driver
Installed Driver Update

NVIDIA GeForce GTS 450 275.33 Your PC currently has the
latest driver installed for
your GPU. No driver update
is necessary at this time.

Here is the log from boinc startup. What do I need to do to get the GPU oprating again? Thanks.

Reboot your system first. That may break the spell.
Else try to reinstall 6.12.26, see if that one can still see the GPU.
If that one is also 'broken', reinstall your videocard drivers.

(before other people point out the daemon thing, it's Windows XP. That one can run BOINC as a daemon/service & use GPUs).
