Dear all,
before installing a separate GPU (nvidia Geforce 210), I crunched also GPU projekts with the on-board AMD Radeon chip. Now, after istalling the Geforce, Boinc states "GPU not found".
Boinc: newest version 7.4.42
Eventlog at startup

Does anybody has any suggestion? Is there a menu/file to edit the use of GPUs
Would be great!
cheers,

Some motherboards don't allow onboard GPU (VGA) devices to be active at the same time as expansion cards: others allow both to be active, but require dual graphics to be enabled in BIOS. Sometimes, a GPU can only be used if it has a connection to a monitor or dummy load.

In short, this is likely to be a computer configuration issue, rather than a BOINC issue.

Sorry, problem solved by itself, the GPU was missing only in WUs requiering an AMD/ATI-GPU...now, WUs for nvidea were downloaded and everything goes well...my fault and impatience...
