Hangs/Freezes on X-25M Windows 7

Hey guys,

I just installed a new ssd (X-25m) on a clients computer along with Windows 7 64bit and 8GB of RAM. The computer hangs for anywhere from 10 seconds to 30 seconds+ and sometimes just freezes up all together until I restart. Sometimes, it freezes icons and I can still use the mouse, and can double click to start a program, but it won't start up until it unfreezes, then everything I've opened suddenly opens all at once. Other times, even the mouse is frozen, and I have to wait 30s to a minute before I get it back.

Things I've tried- all Windows Updates, and updated all chipset drivers for the mobo (MSI P6N SLI Platinum)
