Choppy video/audio on Modern Warfare 2 after SSD install

Howdy,
I recently cloned my OS and a few other things to a Samsung 830 128GB SSD. I went back to play MW2 (hadn't in a while) and have problems. If I set the video settings to 'optimal' in the game setup screen, the sound is choppy and there are video 'artifacts' (black lines that go from me to the horizon hopping in and out) and if I set the game to my monitor's native resolution, the FPS goes in the dumper so I can't tell if the sound is buggered still or not (that was a solution that I found online). Previous to the SSD, it worked fine. Drivers for the video card are up to date, even tried the latest beta driver to no avail. Most of my applications are installed on my D drive (always have been), the only thing I migrated from old C: to SSD what what was on C: already (OS, Office, a couple of games and utilities) I'm using about 75% of the available space.
Anyway, if this rings a bell for anyone, please post. I'm going to try running other Steam games esp. the other MW/COD games to see if the problem is more global
Cheers!

I have reinstalled the current driver post transfer, installed beta drivers over that, then rolled back. Audio drivers not reinstalled post transfer. I'll uninstall both and reinstall. Shouldn't be a hardware issue, the system is about as stable as it ever was and I tore it apart and reseated everything (except the CPU) when I added the SSD. Dusted it out really well, etc. Might be that I'll have to reinstall windows and everything else, but we'll see about that. Thanks for the reply, I'll report back with results.

As AstaLaVista mentioned about to re-check everything is seated properly is a good idea but if the problem still exist after re-checking everything than your best bet is to Re-Install everything that will surely remove all doubts and eliminate the issue :)

Quick update: I decided to do a clean OS (and everything else) install. It's gone rather smoothly and quickly, I was up until 1AM babysitting the last of the Windows updates. System has a higher 'Windows experience' value than with the same hardware last week. I haven't tried any games yet (still downloading). As a side note, I've been playing Battlefield 3 online for several weeks and had no issues related to the machine other than the graphics driver 'blink'. So anyway, tonight I will try MW2. If it's still icky, I'll reinstall it. More to follow and thanks for the replies. I'll start wiggling hardware if all else fails.

I went through my Steam games and of the MW series, only COD MW worked. BFBC2 worked, Black ops broke, MW2 broke, MW3 broke. I uninstalled them all and am reinstalling MW2 to see if it works. I'll update when I know something.

blew away Steam, reinstalled MW2, no joy. I will wiggle hardware tonite.

All,
I tore down my machine to the bone, cleaned up the video card (guess I didn't do such a good job last time) cleaned up the wire rat race and now it plays fine. case closed, I dont' think it was the SSD.
