Win7 PC randomly losing power during screensaver

Hello all,
  have a real stumper for everyone.  I have a new Win7 built PC in for repair.  It was built less than two months ago.  The PC is randomly losing power during the screensaver.  I have gone in and disabled all power management features that I could find.  I checked the dump files and ran a Whocrashed test and the PC IS NOT BSOD'ing.  I swapped the hard drive into a new build with a different motherboard and similar peripheral's and the same thing is happening.  When this happens, the power light is not flashing (a normal sign of sleep mode).  And any keystrokes or mouse movements or button clicks do nothing.  Upon hitting the power button, I get normal post and boot screens.  PC functions fine while in use.
  After playing around with alot of settings, a co-worker of mine went in and completely turned off the screen saver.  Now the PC is not randomly losing power.
  Any ideas if there is a hidden setting in the power management somewhere that I am missing?  I had turned off the feature for computer sleep and monitor sleep, also went in and disabled the hard drive from going to sleep.

I got this way back in Win7, but I thought it had been fixed.

Do you use auto-hide taskbar?  

If so, turn it off and see if it fixes the problem.

No auto-hide taskbar issues.
I think it may have something to do with your video card or not enough power to power the video card if it is dedicated. I would first check for the latest drivers for your video card then I would make sure if you do have a dedicated card that any and all power connectors are connected to the card and the PSU is large enough to handle the cards under load.
have you tried to calibrate the battery? This is done in the BIOS.

Is your new built PC a brand one which has an individual power management utility?
Control Panel\All Control Panel Items\Power Options\Edit Plan Settings -> Change advanced power settings

Have you set the settings to Never under the Sleep option?

ok, i think this is all the responses i have for everyone.

  No it is not a dedicated vid card, it is an onboard vid card.  And it was doing the same thing in a different new PC build with a 500W power supply only running normal peripheral's no extra cards.  Just a SATA HDD, SATA DVD/RW Drive and the motherboard.
  And wantabe2:  I have never messed with any settings in the BIOS for the battery or is that only for a laptop?  this is a desktop.

I'm just stumped as to why this is only happening when the screen saver is on and not any other times.
And yes I have checked for the latest video card drivers and I have them installed.
Have you tried to sfc /scannow in elevated command prompt (cmd)?
check in the BIOS event log....also check your Windows event log to see what it says. What ever is happening should be logged in one of the two places.

Hello all,
  I looked into the Windows Event Viewer and found some critical errors. Not sure if they have anything to do with our problems.

thanks for the reply.  Yes I made sure that both are set to Never previously.  Customer decided they needed the PC back so hopefully they will not turn the screensaver back on.
