I change the casing with the new one, but when I pressed the Reset button, the CPU fan also started later this time, and when it starts, the system shuts down, a few seconds after that, the system starts and shuts, and starts and shuts continuously.
I had to unplug my PSU and pluged it in again, start the system, and it turned on just fine. the problem is that when I use the reset button, the above thing repeats.
Any suggesstion to solve the problem.
