Dual Monitors Fail to retain position after Sleep

On my Win7 Home Desktop, I use two monitors in Extended Mode utilizing a NVIDIA GeForce 9500GT Dual Head video card. My main desktop is on Monitor #1 and I use #2 for E-mail as an example. The problem is when the system is awoken from Sleep Mode, the displays switch Positions. The immediate cure is to go to the “Change the Appearance of your Displays” and click on“Detect”…. The monitors then switch to the correct positions with no further prompting. The monitors show they are in the correct order on the GUI. This only happens after coming out of“Sleep”. I have disabled the ASUS onboard Intel Video card, and done all needed Updates for the system. I have uninstalled and reinstalled the drivers with no success. Inquiries to NVIDIAand Asus blame Microsoft. WEB searches reveal others suffering this same issue,but no successful cures that I can locate. I typically install a fresh copy of Windows at least twice a year, and this is definitely an intermittent issue as I have replaced all the components at least once and sometimes the issue goes away. I am at a loss for a fix on this very annoying problem, and hope a fresh look might reveal a soloution!
