Had my computer on last night, tried waking it from sleep which took a few minutes and even slower to do anything eventually freezing up.

I had to force shutdown but now the pc won't boot into windows, I get a message "" reboot and select proper boot device or insert boot media ""

I can enter bios but it takes a long time, menu then works fine, no details on a failed drive or bios issue.

Anyone know why this has happened? Failed harddrive? Windows corruption?

Win 10,Ryzen 3600, 2 hdd 2.5 1.5tb, rtx 2060.
