Okay. So I’m really starting to think there could be compatibility issues with your RAM and motherboard. I looked up the memory and on Newegg it says it is supported at the 1600 speed, but that is overclocked.
That DQS message means that windows had to lower your RAM speed, but obviously that did not correct the problem because it is still not working. (thanks windows
I looked on Biostars website and it states that the memory you have is supported only at 2GB not 4GB, but that may not be accurate. Here is the link of supported memory for your motherboard. BIOSTAR :: TA890GXB HD :: Memory Support
You should still be able to use 4GB with no problem though.
You may need to try a lower speed RAM with a lower voltage. I’m still thinking it could be a voltage issue from what I read about in past posts. You may also want to look over that list of supported RAM and start from there. I’m not absolutely sure this will solve your problem though.
Maybe someone else on here has a better solution then me. This is just what I read about in the past on this particular issue.
