Is my PSU dying?

Hi guys,

Yesterday I upgraded my Socket 939-based system from a 3500+ to a 4200+ X2. After the installation, I noticed some weird readings in the PC Health area of the BIOS - specifically, the +3.3V rail was spending about 75% of the time reading FAIL.

Since the upgrade, I've had a couple of lockups. I've had one or two similar experiences prior to the upgrade, but it's definitely become much more frequent since the new CPU went in.

I fired up SpeedFan and took about 40 minutes' worth of readings. Here's what I got:

+3.3V:

+5V:

+12V:

Does this look like a dying PSU to you?

Would the CPU upgrade be responsible somehow, or is it just likely that the dual core processor is drawing more power and thus showing up the problem that was there to begin with?

Is there any other diagnosis I should do? Help! :)
 
There's definitely a beta BIOS that's at least one version later, but not much apart from that. I reflashed the BIOS and jumped several revisions ahead prior to the upgrade.
 
Some additional info, FWIW: the PSU in question is a 500W Seasonic. I've had it for a little over 2 years.
