Has my Vega LC just died?

[calken]

Over the passed month, my VLC has been dropping the screen displays and bringing them back on and had been getting more frequent. Today, it started as soon as I got into Windows and now I get no display at all. I've checked the Voltage output of my power supply and I'm getting a 12.3V and 5.5V.

Watching the disk light, the computer is clearly booting when I power it on.

This is a VLC that has had the easiest life, no mining, very little gaming just occasional VR. Having taken it out of the case, it looks brand new and the case doesn't have any of those classic blue smoke smells.

I've been around computers for 20 years and had my fair share of failures but this seems odd.

Has anyone seen or heard anything like this before? Is my Vega really dead? or is my Corsair CX750 too weak? Bearing in mind I haven't launched a game in over a month and it shouldn't be drawing much power on windows.

Chris.

To eliminate obvious things.

a) Use DDU on safe mode to wipe out your AMD drivers
b) Install 18.8.1.
c) Make sure your AIO radiator is vertical facing with the pipes down. If you have the pipes at any other position, is wrongly placed.
d) Do not overclock etc. Let us know how it goes.

e) If you believe is your PSU, go to Wattman and set the card to Power Save mode or Balanced mode. And observe it's behaviour.
The first sets the card to 176W the latter to 234. Turbo sets it to 276W.

I have zero screen output in which to even get into safe mode.

Could it be the cables gone , had a similar proble mwith a hdmi cable that died

So I found a DSUB cable in the depths of cable hell and without Vega in, the machine boots into windows. Stick Vega it in, no display but the machine appears to boot fine.

Now, the plot thickens as I tried a HDMI cable rather than my regular Display Port to HDMI cables and suddenly I got a display. My DisplayPort to HDMI cables are quite long at 3 metres.

Just DDU'ed and reinstalling 18.8.1.

Interestingly, I didn't realise about the pipe position on the AIO - thanks for the info.

OK, Completely baffled.

Started a systematic test of all my cables, one by one they all checked out. Plugged everything back into its original configuration and it works. You can't win sometimes. I did however DDU and reinstall.
