Dead, really dead, Sapphire RX 460 4GB card. Not detected as a PCI-E device at all.

ATIWinFlash from TPU, doesn't detect any ATI discrete card, not with the command-line version, nor with the Windows version.

Device Manager in Windows 10, doesn't show any device at all.

When this card was plugged into two different AB350M Pro4 mobos, with Ryzen first-gen CPUs, I got five beeps out of the BIOS, then it would boot, just no display.

With it plugged into a 2200G APU system, I can plug the display into the APU's onboard HDMI port, and then plug in the card. I figured, if the BIOS were screwed, I could flash it.

But it's not detected... at all. Even when I go into BIOS and enabled "Multi-GFX Mode" (But not "Hybrid GFX").

I think that this mobo is an Asus B350M-E Prime or something like that.

I looked at the card, although I didn't take the cooler off. There was no visible charring that I could see, or scrape marks.

I did notice that the BIOS switch doesn't seem to be present, there's a "Mode 0 | 1" silk-screened on the back, but the tiny little switch didn't appear to be present. Is that my problem? Am I supposed to have a BIOS switch, and maybe it somehow got ripped off the board, so no BIOS boots?

I do have the 6-pin PCI-E cable present and connected.

Hmm, the picture seems to show the back of the card, and a switch present. I wonder how that went missing. :(

Edit: Btw, the back green "Nitro" logo does light up. It's not like power to the card is dead.

Looking more closely at the BIOS switch, it says "Mode 1 | 2", and there doesn't appear to be a switch present. The two solder points on each side are smooth, like there was never any switch soldered in there. So maybe my model was cost-reduced, and didn't have a switch.

(Come to think about it, when the BIOS-mod came out, that unlocked the extra 2 CUs on this GPU, there was no mention of flashing the alternate BIOS position, and then just switching back and forth. Which I would have expected discussion of that nature, had the board come with a BIOS switch.)

I didn't observe the thing "die". I just came back out in the morning, and it wouldn't wake from monitor sleep mode, and when I force powered-off, and restarted, it gave me five BIOS beeps, and no display. So I ended up swapping cards, and it worked. Then I swapped this card into another PC with the same mobo, and I got the same five beeps and no display, but it seemed like it booted the OS.

So I figured, "card died, mysteriously". Only, it seems really dead, not even detected as an unknown device, or as an AMD video card, but with "Code 10 - Device Cannot Start" or something. Nope. Just ... nothing. Although the light on the back-plate lights up, so it's getting power. Fans don't spin, but it has a zero-fan setting in BIOS.

Maybe try to RMA it if its still under warranty? Sounds like corrupted bios from faulty sleep mode or even could be a bad Capacitor.
What O/S were you originally running it on that you put into sleep mode?

Windows 10 64-bit.
Oh that figures... I have heard of horror stories from other users that have these same kind of issues with Windows 10 as well.
Thankfully I have yet to experience sleep mode issues, although I do not use sleep mode ever.
Only issue similar that I had was with Ubuntu Mate locking up in screen saver mode during installation and I would have to hard reboot to get back into the desktop.
Anyways any chance you can try an RMA?

RMA or get a better card IMO. 460 is relatively low end.
