The computer began shutting down repeatedly due to a sudden power failure.
Hey there! Your PC built in 2014 had a sudden power cycle this week after you frequently woke it up from sleep mode. It started acting up after you used OverLAN for at least once a week. The main parts were: a high-end MB, an I7 4790k CPU, spare i5 4690k, RTX 2060 GPU, Hyperx Fury 2x8GB RAM, a Seasonic 650W PSU with M.2 SSD and HDD. When it crashed, a wake packet failed to power it on, and it shut down repeatedly every couple of seconds. I tried disconnecting non-essential hardware, reseating cables, changing RAM slots, using only one CPU, switching the GPU, checking voltage with a multimeter, trying boot without CPU/RAM, removing the CMOS battery, and even swapping the motherboard outside the case. Still nothing changed. It seems the memory module might be damaged or faulty, but there are no obvious signs. It looks like you're facing a tough situation—maybe it's time to consider replacement parts or professional help?
Replace the CPU by submerging it in water once the board is completely discharged. If this doesn't help, you're in a tough spot.
I've repeatedly tried reinstalling. I've used both the i7 and i5 models. I'm still unclear about the "dunk in water" process. It's hard to imagine submerging your motherboard in water for help.
Remove the board without any connections, take off all heatsinks, extract the CMOS battery, remove the CMOS chip and short the power button for two minutes each. This fully drains the board. Then spray water over the board making sure everything is soaked, submerge it in a bucket of water for about an hour (or use the dishwasher), and let it dry for two days. This thorough cleaning should resolve the issues, though it can be challenging with restart problems. Most boards usually fix such dead spots after repeated soaking, but it can be frustrating.
