I tried to upgrade my CPU from an FX-8350 to FX-9590 on a previously stable system but now every time I boot into windows it freezes, maybe at login screen, maybe right away, maybe after 5 minutes, sometimes after a few minutes of doing nothing and not logging in. The screen freezes, the clock stops, the mouse and keyboard don't respond, I've tried leaving it for 15 minutes but it doesn't come back. There are no error logs and no blue-screen crashes.
- I tried different RAM but it was the same, XMP and default,
- I tried a fresh W10x64 install but it's the same,
- and I updated my BIOS and tried default settings.
- I even tried swapping the PSU..
- My old 8350 is back in and it's stable again.
I've ordered a new motherboard as that is the only thing I couldn't swap, arrives in a few days (ASUS 970 PRO GAMING/AURA)
If the problem persists in the new board then I'll RMA to Amazon (UK), if the problem goes away I'll presume the current board doesn't support it properly (Latest BIOS says it does)
