Well, sometimes my Dell Inspiron likes to randomly shut itself down mid-game, but it seems like it doesn't fully shutdown, and I say that because the keyboard will stay lit up, but the blue internal PC LEDs are off as if it is off. I will have to then pull the main power cable from the PSU and re-plug it in to power on the unit.
The power issue happened randomly today, so when I booted back up I tried using Dell's SupportAssist tool to see if it would turn up anything, but I immediately got a BSOD crash once starting the first diagnostic step. Clearly something is up.
I'm fed up with this Dell PC and looking to never buy one again. I will admit though that I did upgrade the GPU and PSU on this thing and Dell's are reportedly a pain when it comes to customizing, so some of this may be my own fault, BUT this PC -no joke- has had issues since I ever bought it and even had some parts swapped while under warranty by Dell early on.
