The R9 270 was sold years ago so I worry it's not "new." The 2GB 270 was shipped in 2014 so that's 5 years old right there. The motherboard had a new revision shipping in 2017 but the odd choice here is the old AMD. I'd go back to your working setup for now and ask if this is all that new.
The problem with this could be drivers or hardware. If you want to try the 270, start with a WORKING PC. Now run DDU then shut down. Now we are ready for the 270.
"GPU drivers up to date using manufacture auto-detect installation." is fine if it works but folk only bring me the times it doesn't. For the drivers we get them from the maker. Here's a primer on that:
My computer randomly reboot after I put in a GPU. I’ve reseated all components multiple times. Dust free. Bios updated. GPU drivers up to date using manufacture auto-detect installation. All components specifications set to default including bios settings, no overclocking.
I haven’t done stress testing because I’m not good with those readings yet. I thought about contacting motherboard manufacturer and graphic card manufacturer to see if both components are compatible together.
Mu guess at this point is reboot the pc over with fresh windows with default settings in case my other programs like adobe photoshop or big programs might of cause the random reboot. ——My other guess is maybe the graphic card is defect somehow. I do not think it is my tier 1 PSU causing the random reboot.
Lastly, I might just buy a new GPU to know if the current GPU is bad or my motherboard.... I might want to take it to a computer specialist and have them diagnose it in the end..basically I’m paying for knowledge.
Let me know your thoughts. Thanks.
