Periodic "Windows 7 Build 7601 This version of windows is not genuine"

I thought this was solved, but it happened again.
My win 7 is once again not geniune...

If it means anything, before my original post, I had just switched a 1gb ram card with a 4gb one.

Seems like a good idea to check.

Also, I recently got an error message saying "An unauthorized change has been made to windows. Please reinstall windows and reactivate, or use system restore to undo these changes."

I haven't done anything, and there has been no malicious software on my computer.

Also, I have heard a rumor (actually, I read it) that windows cannot accept two hardware changes at once. Since I removed and replaced both of my ram cards while I was upgrading one of them, could this have caused it? Is this a actual problem, or is it just a rumor?

I know that I inserted both ram cards correctly too, and I properly shut down my computer prior to changing them.

I'll run Memtest overnight, as I need to use my laptop during my waking hours.

I restarted the laptop, and the not-genuine message is gone.
However, I refuse to believe that it's really been resolved...

I'm still going to run Memtest overnight, and post the results.

As I expected, it's back.
Also, I let memtest run overnight, but it wasn't as I hoped.
It only just made two passes (the AMD C-50 processor only has 1ghz pf processing power, I'm not too surprised, but I expected at least a little more)
Eventually I needed the laptop, so I canceled the scan. It found no errors, though I can't say how accurate that is with only two passes.

And Windows is still not "genuine".
