|Initially, this only happened about 10 minutes after a cold boot. The computer would just shut off. No shutdown dialogue, no error message, nothing. Just shuts off like I pressed the power button. Then, after starting it back up, it would either start up just fine and have no problems for the rest of the day or it would shut off again (either mid boot or after booting up) and then maybe one or two more times after before being fine for the rest of the day. Sometimes when shutting off mid-boot it would give me a BSOD or the screen would just be black. The computer would be on, but nothing would be showing on the screen at all. The mouse and keyboard would not be on, either. Anyways, I looked in the windows event viewer and it doesn't have the event listed as being due to an error or power failure or anything. All it said was "The previous system shutdown at <time> on <date> was unexpected."|
However, since last night the problem has changed. Now the computer just shuts off whenever it feels like it. Completely random. Seemingly no rhyme or reason to it. I just recently thought that it might be an issue with the graphics card, considering I decided to open up the chassis and take a look at it while it was running just to see if there was a problem with the fans or something. The fan on the GPU starts, then stops, then starts, then stops, and does this over and over. I've heard that this is not usual behavior for a GPU fan. Though, I'm not so sure now that the random shutdowns is a side effect of the graphics card overheating. When I look at the temps in HWMonitor, the graphics card doesn't get any higher than 65 degrees Celsius when idling. In the event viewer, for some reason the event I had previously listed doesn't even show up anymore. However, I do notice that there seems to be a spam of events listed as Kernel-Power that say "The kernel power manager has initiated a shutdown transition. Shutdown Reason: Application API".
Can anyone make anything of this?
