Kernel Power error after Win 7 and RAM upgrade

Question

Hello,
I posted earlier on the subject of win7 and ram upgrades.  I did both and it seemed to go fine.  I did the ram first ... replaced a 667Mhz 1gb with a 800Mhz 2gb.  A couple of days later the computer just shut itself down and restarted.  Since then it has done it another 5 times, seemingly at random.  Yesterday I decided to spend some time looking into it and found the 'event log'.  All the shutdowns are recorded as 'critical'.  A search on the web/here showed other occurences of the fault associated with drivers as much as anything.
After I did the win update I did update almost every driver with ones from this site.
Other than the shutdowns the only issues I have which are of very mild concern are the length of time the fingerprint reader takes to be present and that occasionally the cursor is unavailable for about a minute after logging on. When you try and control it it jumps about anywhere but where you want it to go.   I rolled back the alps driver and that seems to have sorted the cursor issue.
So, details of the shutdown from the event log are as follows.

There's more (I've shown it all below) but it's not that important.  When I looked into it I found details of the problem on the microsoft knowledge base.  Its described here http://support.microsoft.com/kb/2028504.
I believe I fit into scenario 3 for cause and resolution.
So, it seems that win7 and mixed speed ram may be a problem on some computers ... probably only a tiny number, but it looks like the HP3507 is one of them.  I did see somewhere that I could down speed from 667 to 266 which might help with memory compatability but I can't see anywhere on the the insydeH20 bios where to do it.  BIOS is version F18 .... upgraded from F15 as part of the Win7/RAM ugrade.  
Before I swap back to the 'old' memory I'll see if anybody here can come up with any ideas.  It may be that I have to sell off the expensive 2gb memory (ddr2 800mhz 200 pin) for £39.99 from maplin at a bargain price and get 2gb of 667Mhz from somewhere.
The full 'detail' regarding the fault is below.
Bye for now.

Hi DWeiland and Schwede,
Thanks for your replies. Yes I did the runtime engine registry change and also mass compiled the LV7.1 folder and my sourcecode. I still see the problem as I have set the LV adapter as Lv 7.1.1 runtime engine. Now I have changed it to LV7.1 development system. With this setting, it is not giving any error. Thus I don’t see any problem now. The older version of the code had the adapter as the runtime engine for some reason, now I have changed the setting to the development system. I hope that it shouldn’t be a problem.
Thanks again!
Thank you,
Sasi
