Plague of Bugchecks

I suspect its my faulty RAM causing many reboots, but I wanted to get your opinions on it. I have attached 4 of my most recent minidumps for your review.

Thx kim, heres an update:

Downloaded most recent nvidia drivers. though problem still persists. also now have had instances during gaming were computer would freeze and not respond (though mouse cursor still moves). In these occasions I've had no choice but to power off.

You need to download (or re-download DirectX updates and install them)

By the way, are you using any external joysticks or anything like that?
And are you using the onboard sound or do you have a PCI sound card plugged in.
The reason why I ask is because I'm concerned about IRQ conflicts (basically how and where Windows has set up your hardware.
If you have any internal hardware not required (other PCI cards so forth) please remove them (I was going to say disable, but prefer remove)
