Stutter, FRH, and CTD

[banros]

Okay, so I've followed (almost) every suggestion made by STEP, the most major being not unparking the second graphics card (which we'll be calling Nvidia about on Monday since we're having trouble doing it). All of a sudden after restarting our laptop we're getting frequent CTDs (most prominently when fast traveling, but especially anywhere near Markarth and Lakeview Manor); our FPS has gone from 45-50 to 20-35 with a LOT of stuttering when moving at all even when it remains at a fairly stable 35 (went from very high to medium to try and get better FRS attempting to fix this). Graphics Drivers are updated. No other performance issues before yesterday. We could play it in high with just a few FRHs here and there, and now medium is struggling.

 

Our specs are:

 

Alienware M17x

Intel Core2 Duo CPU T9800 @ 2.93GHz

NVIDIA GeForce GTX 280M x2

NVIDIA STRIPE 298.10G

8.00 GB RAM

And three of my own mods which individually have not caused any problems. SonirTavern (just changes Sonir's clothing to Tavern outfit.) BetterMjoll (just some minor face changes.) and Maeva (basically a copy of Gormlaith, with a changed face.)

 

Even with UFO and its two addons at the bottom of the list (as is suggested by the modder), it doesn't change the problem. What gives?
