R9 390 Display DVI does not work

I have a similar problem to the one described here DVI not working with R9 390 . Only difference is that i know for sure it should work just fine.


I have a MSI Radeon™ R9 390 which I have been using for some time now in a dual display configuration, 1x 27" ASUS and one 4k LCD TV. I have been using this configuration with no issues for almost 1.5 years up until two days ago, when during a game my PC just lost power.


Seeing how it started up again just fine, I thought the problem was my Intel proc finally overheating and initiating a shutdown. After that i just started my PC again and it worked with no issues.


That is until yesterday, when everything was working fine, i was not even using it at that moment, just playing a movie, and for no reason my monitor connected to the DVI port suddenly lost signal. Looking in the windows event log I can see just one GPU related error at about that time, which after a quick google search seemed too generic to investigate further...

After a lot of testing i have reached the same conclusions as in the post above:

1. Clearing all drivers and reinstalling does not work, tried older drivers as well and still no luck

2. Without any AMD drivers, just using the Windows 8.1 defaults, the card mirrors the image on the two displays no probs (although i don't see two displays in settings, just one)

3. As soon as i install any AMD driver, the DVI display dies (it has nothing to do with the displays, if i switch the HDMI between them they both work fine). The same with older drivers (initially i suspected a driver update was to blame)


As I was stuck with no further ideas i started reading the post above and I came across one explanation from warpfact0r10 saying the blame was with the PSU. Reading this, some things start to add up for my symptoms and config (i have an 8yo Sirtec 620W PSU), however, as i don't have any 650W PSU around, my question is this:


Has anybody else encountered an issue in which due to a faulty PSU the R9 390 behaved odd ? Or is it even normal for a GPU to "partially" work if it has power issues ?


I am also interested to know if my card could have been damaged in any way ?.. currently the DVI is the only issue but maybe something else lurks under the hood ... is there any way to check ?


Thank you in advance for any feedback !
