巴西采购需求：CPU散热器、风冷散热器、风扇散热器、液冷CPU散热器、水冷散热器、ARGB散热器

I'm reaching out because I'm experiencing an issue with my device. It seems that the software no longer recognizes it, and the LCD screen only displays a blank factory screen with some white dots. Could you please assist me in troubleshooting this problem? I'd appreciate any guidance on how to resolve this issue and get my device functioning properly again. Thank you!
