Thanks for the help.
I did not find the minidumps folder in windows, I looked at the startup and recovery settings, it is set to kernel memory dump, I switched it back to smal memory dump 128KB and waiting for next failure (hope it's not while im writing it now
I was thinking of the USB devices too, I used to have 500gb external hard drive, logitech webcam, wireless keyboard and mouse and another trackball while im working on TV. Now I have only the keyboard and mouse plugin and still getting this issue.
btw, I have the 450w power supply comes with the case, I think that should be enough?
Again, thanks for check in and have a good night!
