Random drop in FPS on CoD4?

THREAD BUMPED BECAUSE PROBLEM IS BACK!
Bumping this thread because the same problem has arose. Every single game is stuck and won't go above 31FPS with VSync off (including games like Minecraft and FEAR 1 and on Minecraft I was hitting an easy 500FPS!)
I'm at college now and I can't just reboot to factory settings like last time. Any help would be very appreciated!
I'm very very desperate and I can't do a clean install..


Hello everyone,
I have fallen in love with my new MX14 R2.
I have been using it mainly for FO3 and CoD4 and today I went to go play some CoD4. None of my settings have been adjusted, in nVidia it is set to run with the nvidia chip not the intel yet for some reason I'm stuck at 31fps. Never under and never over.

I had been running at 91fps without movement and it was perfect and I had absolutely no problems. I turn on my computer boot up CoD4 go to my favorite server and I'm stuck at 30FPS. I've tried tons of other servers both full and empty but I can't change my FPS. Its whitelisted in the nvidia panel, none of my settings have changed at all. I literally just booted up the Alienware and jumped into CoD4 and have been experience these problems for a few hours. I've adjusted settings back to default then to where they were, I tried running through xFire and Steam and I've tried just right clicking and choosing the nvidia chip to run CoD4 none have any affect. Does anyone have any idea how to fix this? I've been trying for the last few hours but nothing seems to work?

EDIT: I tried running Fallout 3 (the other main game) and it is also stuck at 31 FPS and its been running at a smooth 60. Help?

Edit 2: All games I have tried won't budge above 30FPS (Included games (all of which ran above or at 60FPS before whatever changed this) Portal 2, Portal 1, WoW, Call of Duty 4, Fallout 3, Fallout New Vegas)

Edit 3: I've had to restart my computer twice now since this started happening. Once because it froze up. Once because my sound across my laptop started to sound like a robot through water using both speakers and headphones. I'm really unsure of whats going on. My computer seems to run fun on the internet and playing videos but I'm locked into 30FPS and now having random sound issues? Anyone have some ideas? I believe the topic of this thread has changed to all games experiencing FPS problems but I can't change the thread name apparently. So yeah, I'm getting kinda desperate. Its been a few hours that I've been trying to figure this out but I'm not finding anything.

Edit 4: Tried rolling back to the old Nvidia drivers. No dice.

Edit 5: I'm really hoping someone will respond to this. The forum title is kind of misleading I feel at this point but for some reason it won't change ><
Anyway, I decided to drop everything down to the lowest it can go on both CoD4 and Fallout 3 (Which were running at a smooth 90FPS and 60FPS respectfully before today) and still stuck at 30FPS. The only logical thing I can think of is that somewhere in some area (I'm not sure where) there is a lock on my FPS for gaming. I'm not sure if it is something to do with nVidia or the system or something but I just don't understand. I haven't touched any settings on the laptop, haven't done any overclocking, haven't downloaded anything. I literally booted up the laptop. Double clicked the icon jumped into the same server that I've played 20-30 times before and am now stuck at 30 FPS. Everything that was plugged in is the same. Nothing changed (at least that I did). Is there some sort of locking feature somewhere? Is there way to check for this?

Update : I called Dell. They completely reinstalled drivers of both the Nvidia and Intel. Didnt change anything...

 

Bump for all new info?
Dell was surprised after running there heaven benchmark they barley got 25 FPS

I feel like there is some sort of lock because it NEVER went past 31 FPS. Is this possible?

 

you should try whitelist the game, maybe it will help you.

 

Ive done that with all the games.

I even set it to only use the NVidia GPU

 

Mine is coming in tomorrow and I am going to play CoD4MW on my AlienWare too.

I will see if I get the same problem, but for now you could try this:

Is Sync every frame ON? if so turn it off.

try to cap the FPS to 90, type this in the console
/com_maxfps fps 90

If you use Fraps or another program to see your FPS, turn it off
then type
/cg_draw fps 1
into the console

Try re-installing CoD4

try servers without PunkBuster


Also could you post the settings you are using in CoD4MW?

Sorry, this is all I can do till tomorrow
