Hello Romanya,
Usually when a customer sees this, it is due to an incompatibility with our software and the current GPU/GPU driver. The first step is to look up the GPU in your system and look on either the PC or GPU manufacturers website for any driver updates. If that does not work, send an email to support@signalhound.com with information about your PC, and we will see if we can work through it.
Regards,
Andrew
