Meanwhile, graphic cards have big and easy-to-access rotors, which can be easily broke if touched while running, for instance, by the user much earlier before the malware injection. Malfunctioning cooling system, together with the very high load caused by Bloom.exe virus can easily lead to graphic card failure3. GPUs are also tend to have increased wearing when used for crypto mining. It is likely an unwanted case when the performance of your video card plunges 20-30% only after several weeks of being exploited in such a way.
