For the past two weeks, my PC has been beeing four short beeps during normal operation (not during the Power On Self Test). The PC is on all day but is under minimal stress and the CPU is 36 Celsius when idling (I ran Core Temp). Im not 100% sure whats causing the beeps- ive tried ran Memtest and it passed with flying colours and the CMOS battery is fine.
