So this just started happening today. I was playing a game perfectly fine, no issues since booting up my computer a few hours prior. Randomly out of nowhere my computer boots down and boots back up. I figured it was probably from a brown out or something that we've been having lately (Like 4 or 5 in the last 2 weeks alone) and proceeded as normal when it rebooted. A few minutes later it reboots again but this time the troubleshooting LEDs kept switching between the CPU and dram. This proceeded on for a few minutes before booting in for a split second and then going back into that cpu and dram loop for another 30 seconds. After successfully booting again, it started to repair my drive and at this point I was just letting it do it's thing. A few minutes later it's up and running... for another 10 minutes. It does its reboot thing again and once it brings me to the log in screen I shut my computer down and flip the power supply off for 5 minutes. Turned it back on and it works fine. 2 hours later it did the same thing but didn't repair my drive. I repeated what I did, shut off my power supply for a bit and also reconnected my cable for cpu power just in case it wasn't connected properly (which I don't think it could've been since it's never once done this for the 10 months I've had it built). A week or so ago I did have to do some rewiring because the power supply was getting a little noisy since me and my dad didn't realize we installed it facing upwards so I flipped it over but it worked fine all the way up till now. I'm baffled on what's caused this. Could it have been the multiple power surges leading up to this and something might've fried in the motherboard? A faulty connection? Maybe the drive? Any help is appreciated and I'll leave my parts list in the description below. Thanks in advance.
