Title says it all. It is a bit annoying and I think that cpu might be overheating. My monitor happened to shut down 2 times and that was not happening before beeping. Cpu - i5 2400 at stock speed, rx 550 2gb, 4gb ddr3 ram. This pc is old like 5 years, and I have not replaced thermal paste ever. I'm buying a new one soon so I'm not planning on upgrading it or whatever. Btw cpu idle temp is 40°C, is that good or no?
