Windows 7: Computer sound distorts then freezes, no BSOD

Hello, when the problem happens, it starts with my audio become distorted and slow, making the mouse also slow. After that the mouse freezes along with all other things going on and the audio loops back and forth, forcing me to do a hard restart. This problem happens anywhere from a day to a few week. Sometimes when windows is updating during shutdown, it stays stuck on the same updating step.


I have:
-Replaced the Mobo
-Replaced the RAM
-Replaced the GPU
-Replaced the PSU 3 times
-Replaced the CPU
-Replaced the Hard Drive
-Disconnected the DVD Drive
-Ran Memtest overnight with no errors
-Changed HDMI cord
-Unplugged front audio and USB ports
-Reformatted my hard drive many times



Please I need help or suggestions, I've had this problem for almost a year now
