My PC is quite old and is now consistently shutting off under load (Streaming, Watching Streams or Playing a Video Game), it does not give me much time before it quickly shuts off after starting one of the mentioned loads, for example I can not even finish one death match in Valorant before it shuts off

I am suspecting my GPU is overheating and is causing the shut downs, often when my PC is idling the fan would rev highly at 3000+ RPM

I would like to isolate the problem and stretch out my PC for a few more years, If I can keep the same build that would be great but I am thinking of testing the PSU, Change the GPU, Change the thermal paste for GPU, maybe even for the CPU (No signs of abnormal temperature)

Please let me know what you think, thank you!

post a hwinfo sensor page reading on idle and load and when was the last time you dust off system and fans also case model and number and how many fans in the set up of them .

Prior is idling and latter is streaming a video on Discord

I dust it monthly so it is pretty free of dust bunnies, about a week and half ago was the last time

There are 2 fans, 3 if you include the one that is part of the 295x2
