Win7 product key disappeared

I have a 2 yr old HP with Win7 Home Premium SP1 I bought from retail store with OEM software installed. All of a sudden, I am now getting the messages that my Windows o/s needs to be validated. Of course, the OEM CDs I got with the system are missing. I used Belarc Advisor to find the Windows Product Key, but when I try to reneter it on the Windows Activation screen, I get error message:

"Code: 0xC004C008

The activation server determined that the specified product key could not be used".

So, do I need to contact Microsoft maybe or ??? I get messages that the 30-day period has expired, but I can still (for now) use the computer.

Any help would be greatly appreciated! Thanks in advance.

btw - I did need to do a lot of cleanup tasks on it after that started. I ran a full MalwareBytes scan, deleted some stupid web browser toolbars and other general cleanup tasks. There are several free games that have been installed, so I'm guessing one of them had some nasties in it that caused the problem.

Yeah. I have to remote into the system in question and they are away for the day. Hope to have that info up tomorrow. All I had was a few screen prints from they system info that are not as detailed as the MS Diagnostic Tool output.

Here's that diagnostic output.
