Problem with unsigned drivers I can't fix

Hello,
I'm running Windows 7 x64 since October without any problems. Yesterday I had to change the CPU cooler (and I cleared the CMOS) I found out that my TV tuner (twinhan DVB-T) drivers weren't installed anymore. I don't know if those two actions are linked somehow cause I had a system update from windows update in the same day before my discovery that could have changed some kernel configuration, wanted by MS of course.
The problem with those drivers was that they're not signed so I had to enable Test Mode with a tool dseo13b.exe and everything was working just fine.
Now this! I've run out of options I don't know what to do anymore.
I tried to enable test mode from tools, command line, disable the signature control from registry and services. NOTHING they won't load. I also tried to sign the driver with this guide but it continues to be read as not digitally signed even thought it clearly is from a verification from Microsoft WDK.
So every time I boot the system I get an error that says the .sys driver could not be loaded because it's not signed and I have to either cancel the sys from system32 folder thus it won't load at all or press f8 and disable the signature enforcement control which makes the driver work, but it only applies for the current session. At the next restart I'm back to the start.
I found a "script" called ReadyDrive Plus that automatically selects that option in f8 on boot but I DON'T KNOW WHY since I have Linux installed too with GRUB after I select in this order :
1- from GRUB windows 7
2- from Windows loader ReadyDriver Plus

It goes back to GRUB loader! So useless!

Apparently my only solution is to select f8, do you know any other method to select it automatically? Or why the hell Test Mode doesn't work anymore ?

Why would you clear your CMOS when changing a CPU cooler?

What happens when the CMOS is cleared or "reset", is that all the BIOS settings go back to Default.

Did you check you BIOS settings to see if they may be affecting some things?

If you feel the unsigned drivers are the problem, you can override them like this.
Open the Start menu and type cmd.exe.
Right click on cmd.exe and choose Run as Administrator.
If the UAC pops up choose Yes. Otherwise.
In the window, type this and Enter. (This must be exact. Note the - before set, and the cases.

bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS

You will get a message that the operation was succesful

Now type this with ditto message.

bcdedit.exe -set TESTSIGNING ON
Restart the computer.

If you are using Ultimate or Pro, you can also do it like this, but the method has been reported as not always effective.

Type gpedit.msc in the Start to open the local groups policy editor.
Expand Administrative Templates (it’s under User Configuration).
Expand System.
Click Driver Installation.
In the right panel, double click on Code Signing for Device Drivers’
Choose Enabled in the window that appears.
In the options, choose Ignore’.
This disables the drivers signing in Windows 7.
Click Apply, OK. Restart your computer.

Nibiru2012 I did that because I had to unmount everything (long story) and the MoBo wouldn't load if I didn't clear the CMOS, anyway only some values I changed in the first place, nothing that could affect the driver thing!

davehc : I already did ALL THAT, it doesn't work! and that's really ODD. The first time I tried months ago enabling test mode was enough, that's why I was thinking that maybe MS changed something with a system update.

You may have to do a clean install to clear it all up.

Did you do a System Restore? It may work.

OR remove the TV tuner card. Uninstall all the drivers for it and then put the card back in and reinstall the driver. It may work.

Last resort... clean install.

I don't have a system restore point.
Do you really think that removing the TV tuner could solve the problem? It's Windows that doesn't disable the driver signature control!

IF you don't a system restore point, then you must have turned off the System Restore function.

What I'm saying is that removing the component that is causing issues and reinstalling the drivers my solve you problem. Maybe not.

What may have happened when you cleared your CMOS is that the IRQ assignment may have changed for the TV tuner card. The drivers may be all discombobulated because of that.

I don't know where you got the idea to clear the CMOS from, but it certainly wasn't necessary for merely changing out the CPU heatsink cooler. I know this from quite a few years of experience. You were just changing a piece of hardware that does not directly interface with the motherboard at all except for a 3 or 4 pin connection for the CPU heatsink fan. Even if you had to pull the CPU itself and the RAM, video card, and all other parts leaving the mobo bare; there was no reason to reset the CMOS.

If pulling the tuner card and reinstalling the drivers doesn't work then your only recourse, if I'm not mistaken, is a complete reformat and clean install.

Also, if you have separate hard drives ,the put Windows 7 on one and Linux on the other, if you haven't done that already. Everything will run much smoother that way.

As I said I didn't get the idea from anywhere, I removed the CPU for cleaning up too and I don't know why the system won't start until I cleared the CMOS!
I'll try removing the TV card but I'm getting the sense it's a software problem and I'm tired of this "windows style" solution = formatting!

Hi,
I tried to unplug and plug the tv card and unistalled the drivers
Now I don't get the error at boot anymore. This is like what happened the first time I tried to install those drivers, at this point I just had to enable test mode and everything was working ok, now it seems like the test mode won't be enabled in any way. in fact the TV card in device manager has always the warning image.
is there a way to verify why and if test mode is ON?
Cause if I press "disable driver enforcement" at boot it works!

Well, I wish I could help you more, but I am at a loss to know why this is going on.

Maybe someone else can advise you.
