It could be a false reading. You have so many DMPs and they are all over the place. Shintaro wanted you to run driver verifier because the DMPs don't pin it down.

This thread has been running so long I don't remember what all you tried.
Have you checked the BIOS settings for your RAM? Make sure the timings and voltages are set correctly for your RAM, don't assume the default is correct. Does your RAM meet the MOBO requirements? Are you using matched pairs if your MOBO recommends it? Did you run Memtest86+ for at least 6 passes?

There is a utility to check for driver updates which I only recommend as a last resort because it's not perfect. The problem is that it is only as good as it's last driver database update so there could be more recent drivers. Also the IDs devices give off aren't always exact and it can sometimes install the wrong driver; if that driver is a video driver or something critical you may not be able to boot into normal mode so, getting your driver from the manufacturer is what I always recommend if at all possible.
That being said, it can be used relatively safely if you follow some simple guidelines.
1. Download and install
Device Doctor 2.0
2. Create a Restore Point (type
Restore Point into Start-search)
3. Run Device Doctor and if it finds any drivers allow it to download
ONE driver and install it.
4. Reboot and verify your system is working.
5a. If it is working, Go back to step 2 (create another restore point) as long as there are drivers.
5b. If it doesn't work then ...
- boot to safe mode
- restore from the restore point
- Reboot and go to step 3 but skip over the driver that did not work

If you can't pin it down to a driver or a hardware problem then at some point you might just have to say this isn't working and you have to back up your settings and data with Windows Easy Transfer, format the hard drive, and try starting fresh with a new W7 install.
