BSOD new graphics card

[win7user99]

A few weeks ago I bought an MSI radeon rx vega 56 for my pc and had troubles with software in it. It would give out a black screen, and checking the mini dump files would state that the AMD drivers were causing it. Eventually I found out I was using the wrong driver, and that was causing the issue. Now with the right MSI driver, the card has worked 90%, but isn't 100%. It still would BSOD periodically, blacking out without restarting the pc, all of the pc lights still on except HDD light. I want my pc to stop this, and now the mini dump files say that just the ntoskrnl.exe driver is causing it. After testing 4gb out of 8gb of the cards memory with video card memory stress test, it showed many, many different memory errors (hundreds of thousands). Help, should I just return and get a new one, or is there a fix.
also msi afterburner causes an instant crash with no minidump file.


I have a 650 watt psu and it's plugged in good.

Never got this fixed. Just cut my losses and returned the card to microcenter as I am within the return period. The card's video memory had to be the culprit. RIP vega
