Blue screen when opening ISO files

Scratch that, DVD's don't work either.... I just put in a disk and tried to play it and got the same error. What the heck is goin on?

I looked at my "computer management" event log in my system info and it says "Could not attach to EL Acpi driver".... any ideas?

Roll back yor Nvidiot drivers

Installing video drivers sometimes causes unique issues. The general rule is to uninstall previous drivers then install new ones. Sometimes you have to use registry cleaners to get all of the old drivers out.

After I uninstalled and installed the newest drivers, VLC would no longer show any videos and I had to reinstall VLC and then it worked fine again.

The point is once you install drivers, you may have to reinstall the apps that "hooked" those drivers.
Otherwise think about installing the old drivers again and see if they work.

You could try running system restore and pick the point where you installed the newer drivers. that will roll you back to that point in time - and you could try going through the update again.

Ok well I just tried to update my drivers, uninstall the drivers, install the drivers on the disk, tested my RAM, and finally did a system factory restore (it's a dell).... the problem still occurs. I don't know why VLC works and the others do not. Ive tried like 10 different players and they all crash to 0x0000008E and nv4_disp.dll. What else could it be?

Im goin nuts.

Does this help anyone?

Other than showing you have an Nvidia driver crash, no not really.

I just rebooted my computer again so everything was removed.... then I installed the latest driver upon start up. I tried to open a DVD and bam, same thing, BSOD. I don't get it.

Have you tried the 195.81's?
