Dear all,
I´m a completely newbe in BOINC - so apologize for a maybe stupid question.
I´m using the lastest BOINC Client on Windows 10 64 bit with an ATI 8450G Graphik Card. (Acer Aspire V5-552 Notebook)

The BOINC screensaver started and is working without any problems. But if I interrupt the working process, I see on the top (2mm from the upper edge) of my display a line of unsteady graphic artefacts, which occur, if I am moving the mouse.

I tested serveral setups in the setting of the BOINC client and the errors don´t occur if I am using the GPU permanentely and the work of BOINC is not interrupted by user or if I switch the using of the GPU off completely, when I start BOINC.

I updated to the newest ATI driver but the problem occurs.
Even if I close the application, this graphic error ist there till the next reboot.

I looked for help in this forum and google but I didn´t found a similar description. Any suggestions ?

Greetings

Matthias

Normally when you see artifacts and they linger even after a program that seemingly caused them has left the memory, it is a problem with the hardware. Or with the cooling of that hardware.

Is BOINC using that videocard just as a videocard, or is the graphics processing unit (GPU) on it also capable of running OpenCL tasks on it? Because if so, that puts more load on the GPU than just playing a screen saver does.

Things you can try:
1. Better cooling. It's a Notebook you say, but even those can be better cooled with a cooling pad.
2. If the project(s) you run support using the ATI GPU, deselect its use in the project preferences. You still have to run through any work in cache, but will not get new work for the GPU. If then in time the artifacts diminish or go away completely, it was the GPU.
3. Not run the screen saver.
4. If still under warranty, return the Notebook and have them replace the videocard, if possible. (But since it's probably built into the CPU or onto the motherboard, not easy to do.)
