Massive amounts of BSODs on boot, multiple errors; BE, 18, 7E, 0A

Yes, if the other image does not work, try supplying crash reports from more than one machine. For the possible USB issues, you may look into USB Driver - General Fix for Problems for the machines.

I did not see anything in the reports you uploaded to indicate a USB issue, though. These are usually pretty clear cut. We would have to analyze more reports to be sure, but the one machine that has been analyzed does not seem to have a USB problem.

How was the original image created for the machines?

As far as I know the images are all created on virtual machines. Mind you, I'm aware that doing it this way may cause issues due to HDD drivers and sometimes other driver issues as well.
After this however we usually throw a bunch of software packets on it so it'll have any missing drivers or software.

Anyway, I'll be able to ask my colleagues on tuesday. About the AV and see if the new image works, seeing we had it installed on a newer machine that crashed a whole lot.

You are right that creating an image as was done for those system can cause headaches. I wonder if doing a clean install of Windows 7 on a machine is a possible test that could be run, as well. See if the system behaves any differently.
