New motherboard somehow lead to periodic frame drop in games

[Supertoaster77]

Recently I had to replace the motherboard in my rig. Unfortunately, after a short while of playing games, the framerate drops down to about ten for thirty seconds or so. It's not a temperature issue, as all my components run relatively cool. I don't think it's an issue with drivers, but it could be.

Specs:
MOBO: Gigabyte GA-970A-D3 S.AM3+ AMD 970 ATX

GPU: AMD Radeon 7850

CPU: AMD FX-8150

8 gigs of RAM

750 watt power supply

Did you replace it with a different motherboard or the same model? Did you reinstall windows if it was a different model?

It was a slightly different model, and I didn't reinstall Windows.

How different of models? A different chipset might need different drivers for the pci-e controller, memory controller, sata controller, etc that aren't working.

Barely different. My old board was a Gigabyte GA-970A-UD3, I believe.

Also, something worth mentioning is that some games experience the performance drop, while others do not. Most notably are online games. All online games experience it at different intervals. Most singleplayer games, such as Skyrim, do not experience it at all.

Just looked at the specs on both of the board and they both use the same north bridge, south bridge and network chip, so a bit puzzling. Maybe try uninstalling the network drivers and then reinstall them, I dunno. lol.
