MDAC is part of Windows 7, so the first thing to do is a system file check which should replace any missing files. :wink:

Open a cmd window as administrator and run

sfc /scannow

i have done that twice and i have used some of the tools and utilities from tweaking.com.
all the sfc /scannow found and replaced were some log files and i then restarted the computer.

OK so the ADO files are missing.

Are you on 64 bit or 32 bit Windows 7?

OK try this.

1. I have attached the ado files from my Windows 7 64bit. Extract them and put them into "C:\Program Files (x86)\Common Files\System\ado" overwrite any files you have there if Windows lets you.
2. Once you have the files there run my mdac repair tool http://www.tweaking.com/content/page/repair_mdac_ms_jet.html
3. Once done try the mdac tester again and lets see if ADO still gives us an error. :wink:

If you cant replace them that is ok, as long as any missing files got put there is what is important :-)

Something else is wrong then if that didnt fix it and a system file check didnt fix it.

This is why in any of my database programs I have it set to use DAO and if it fails to use ADO. This way when one is broken it will use the other.

In this case what ever happened to ADO must have deleted something from the registry. But I dont know what keys it would need.

Have you ever done a repair install of Windows before? It is where Windows get reinstalled but all your files, programs and settings are saved.

IRQ equal or less than blue screen of death. And since you have Windows set to auto reboot on a blue screen you cant read the rest.

That is almost always driver related.

Not sure since I cant see the system.

I would say unhook anything that doesnt need to be on during the repair install, uninstall any antivirus or firewall software as they add their own drivers tot eh system.

And have Windows set to not restart on a blue screen so if it happens again we can get the full error and hopefuly findout which is causing it.

Oh and you can try this tool, it will report the last blue screen and which file or driver might have caused it :-)
