problem with Game lag after new mobo install

This is kind of a combination of things so I stuck this here. If its in wrong place I can move.

Long story short, installed new mobo and it started BSOD. I fixed the BSOD on my own, but now it is running games SLOW lots of lag despite latency being fine. Ran into something similar before with the old one when i first installed the graphics card where it was not "ramping" up but I do not think that is it. I have more than enough power and the CPU is by no means getting hot as it is idling at about 50 C regardless of gaming.

Not sure where to go from here. I am open to suggestions and will answer asap.

All of them.

You say is a new built, right? could be that a new Bios, chipset, audio and video Update is all you need?

Got the drivers from the MSI website and had to uninstall the realtek since that was the cause of the bsod. And the graphics card is up to date according to nvidia experience. With the old mobo and same hardware everything was fine. But now with the new mono this is happening. It is weird.

Well, Audio and Video drivers I usually install directly from the horses mouth, whether that be Realtek, Nivida or AMD.

Are you saying that the Mobos are the same model? I ask because of this.

With the old mobo and same hardware everything was fine. But now with the new mono this is happening. It is weird.

If so, weird that you decided to go for the same mobo instead of upgrading to something new. If not, perhaps therein lies the problem?

Sorry, perhaps I am reading all this wrong.

Its a new mobo. MSI 970a from the old asus board I had
