The issue has been difficult to diagnose. The computer would spontaneously restart at extremely random times. These were not typical restarts: the screen would go black and I would hear the same clicking sound as when the computer shuts off, fan lights powered down... But then less than 2 seconds later the screen would go right back to what I was doing, without even requiring a Windows log-in. If I am in Discord when this happens I have to hang up and reconnect before I can hear anyone and before they can hear me. Otherwise, everything would be uninterrupted. A game that was running would still be running and not paused at all, for example. I researched the issue but never found anything, and it didn't happen that often so I wasn't too worried about it. I never lost any unsaved work because these are not your standard shut-offs or hanging/freezing. They don't show up in the Windows error log. About one year ago the MoBo died. One such shutoff occurred but it was permanent and didn't resolved until the MoBo was replaced. Naturally I assumed a faulty mobo was the problem all along. Then the issue continued until a few months ago when my PSU died. Again, the spontaneous shutoff happened as usual but the computer wouldn't power back on. Jumper on the 24 pin confirmed the PSU was dead, so I replaced it with the one listed above and it worked again.... But the restarts were still happening!! I replaced the graphics card (was a Radeon HD 8950) but that hasn't changed things either. What is going on?? Is there a glaring incompatibility or a part that's known to have this problem on this list? Is it even possible that an SSD could cause this issue? I know it's limiting in terms of space but could that lead to anything like this?
As a little extra information, I have disconnected the case from the motherboard to make sure this wasn't just some kind of wiring issue. The problem has been happening for years now with the case connected to the motherboard (I have confirmed this was done correctly) so I recently thought maybe the case was sending a false signal that the power button had been pressed. However, the problem continues even without the case connected. I also began to suspect electrical problems but that seems to be ruled out based on responses to a previous thread.
