Hello, recently I upgraded my CPU ,GPU and PSU. I downloaded updated BIOS. Cleaned the old GPU drivers and installed the new ones. Downloaded the chipset drivers. Computer started up good was able to do everything like normal. When I loaded up PGA 2k25 it worked for a about 4 hours. Since then, I've been getting complete computer power loss typically when I load up a game but also happens when I stream a movie or watch a hockey game on it.
I replaced the PSU and added a NHD15 CPU cooler to eliminate a PSU issue and a cooling issue.
Temperatures sat around 59c-75c on the CPU and GPU was never above 50c and still end up with the same result. The majority of times this happens when I start up a game like Apex legends and PGA.
I can stress test the GPU without an issue. When I stress test the CPU it shuts off the computer after ~4 secs.
I checked over the events screen in windows but wasn't helpful the only thing that I see that is odd is two motherboard temps being off. One very high (temp #4 100c) and one negative. Temp 4 did slowly climb up and wondering if it's shorted causing a temp spike. Not sure if upgrading to these parts cause the motherboard to fail in some way.
Computer worked fine before upgrading to these parts. Need help! My set up is below. I included original parts in brackets and what I upgraded too.
MB - Asrock B450m/AC CPU - NEW Ryzen 9 5950x (Ryzen 5 3600 old)
GPU- NEW gigabyte RX 7800XT ( power color RX 5700XT old)
