A while back, I made a thread on my old computer randomly restarting. What would happen is that I'd be using the computer, there'd be no particular triggers, whether it be internet browsing or playing a game, in which the computer would suddenly turn off and boot up again. I replaced the power supply from some CiT ATX 500W PSU to a B3 450W as suggested by someone. This worked for a while then 2 months later, the exact same thing happened again.
Eventually, I started using my Dad's computer which was based somewhere else rather than my room and that worked absolutely fine. I transferred his computer to my room and about a month later the exact same thing happened again. Rather than the computer being bought off a website, my Dad's was built over the summer.
Ryzen 5 1400 (w/ Stock Cooler)
8GB DDR4 2133 RAM
GTX 750 Ti 2GB
CXM 450W PSU
128GB M.2. SSD
2TB P300 HDD
Windows 10 Home
Currently, I've run an Antivirus scan and done a memory test. Just some very basic things so not sure on that point but my suspicions point to the wall outlet in my room. Currently, there may be too many things connected into the wall outlet (PC, 2 x 1080p Monitors) although I find this unlikely. It's a strange situation as the computers which I've plugged into this outlet all do fine for a while then they start shutting down randomly after a time period without any warning. Here is a link to my previous thread https://www.bleepingcomputer.com/forums/t/648976/random-restarting-psu/
The difference between my old computer and this one is the old one would shut down randomly whereas this one would shut down when the GPU and CPU were stressed. It's been stressed before in my room but there have never been any problems. Now, whenever I stress test both the CPU and GPU simultaneously, it shuts down after several minutes then reboots. Temperatures get to about 62C under load then stabilise there CPU wise and GPU gets to 66 - 67C so it doesn't look like an overheating issue.
