I am troubleshooting my home PC, it is failing but I can not find souce of the problem.
- Mobo: GA-890GPA-UD3H (rev. 2.0)
- CPU: AMD Phenom II X6 Black Edition 1090T, 3616 MHz (18 x 201)
- Graphics: NVIDIA GeForce GTX 460
- HDD: WDC WD5000AAKS-00UU3A0
- PSU: Thermaltake Evo Blue 550W
- RAM: Kingston 9905471-001.A00LF (2GB x 2)
The mobo manual has no information about 1 loud and non-stopping buzz sound (it's souns more like buzz then beep) seems not common situation. (sound coming from mobo speaker)
So it makes this noise and everything just freezes during this noise. This noise may or may not randomly stop. If it stops then everything unfreezes and windows continue regular work
checked HDDs, replaced one because of to many bad sectors, but second seems fine. It has some bad sectors, but just 0.2%
Tested some components with heavyload and furmark, everything seems fine under heavy resource load
I can not simulate this loud buzz noise behavior, it happens just randomly.
Sometimes computer refuse to turn on after rebooting after that sound - POST is silent. Just have to wait a bit before turn all back, then POST produce 1 short sound indicating all is fine and load BIOS and OS
Help me understand what should I try to figure out what's going on
