Random Freezing. Is 600W PSU enough?

Hi. My new build (thanks to good advice here) is working great. Lots of power. Situations where I used to have to freeze multiple tracks just cruises now! And latency problems have greatly improved. But - ever so often - Windows will freeze. No mouse or KB movements. I have to push the button to reboot. Oddly, it never happens when I'm using it. Only when I leave it for a while and return. And it doesn't do it every time. Temps are fine - around 28 deg C at idle. I have ran Prime95 (temps peek at about 58 deg C) with no errors and memtest6 for 8 hours - no errors. I can't help but wonder if I may have undersized my PSU? Although I checked at an online power calculator and it appeared to be enough.

Here are the specs:
Windows 7 64 bit
i7-2600K (not OC'd yet. Waiting on PC to become stable first)
Gigabyte GA-P67A-UD3-B3 motherboard
Mushkin blackline DDR3 RAM (1600) - 8 BG (2x4GB)
Noctua NH-D14 CPU cooler
MSI N450 GTS video card
Corsair CX600 Power Supply
Cooler Master Case with 5 case fans
3x 1 TB HD's (2 of them are SATA II and 1 is SATA III, all 7200 RPM)
SIIG FW card (TI chipset)

All drivers updated and all Windows updates installed.

One other possibility - my GPU arrived DOA so I had to RMA it. While I waited I installed a GeForce 7300 LE to hold me over. Once the new 450 GTS arrived, I swapped. Freezing has occurred with both cards. Should I have "uninstalled" the 7300? I simply swapped them out and updated drivers. Any chance those old drivers could be the issue? How would I uninstall?

I've tried with/ without FW card and interface. No effect. Tried different mouse/ KB - no effect.

Suggestions? Hardware issue or software issue?

Thanks, as always!!

    Has the machine ever locked up while posting (screen looks scrambled - a bit like snow)?
    We received a shipment of that model... and literally all were defective.

    No - so far I've had nothing like this. System posts just fine. Just acts goofy when it sits idle for a while. Normally I have it sleep after 30 mins, and - as the problem tends to take longer than 30 mins to happen - that usually eliminates it. However, I realize that is not really solving the problem, merely working around it.

    But I have to admit - a batch of defective MB's does not illicit a ton of confidence!!

    Thank you, Jim.

    What audio interface are you using and are you using it as your primary sound card for windows

    I have a Focisrite Saffire. And yes, it is my main sound card for all purposes. In fact I have the integrated audio card disabled in BIOS. I do have a Line6 USB DI, but it just acts as a Dongle for Pod Farm 2.

    What You might want to do is shut the Saffire & the line 6 down then let the computer go to sleep, I suspect the driver for one or the other is having a hard time loading when the CPU wakes up

    Thanks, but I have indeed tried that. I've tried without both interfaces and even removed the FW card. Keep in mind, it is not happening when waking from sleep. It just freezes when I walk away from the computer for a while and it is still running. It has to freeze in less than 30 minutes because that's when it sleeps. But once it sleeps it wakes just fine.

    Thank you!
