I recently installed a palit geforce gts 250 on my dell xps 400 computer. After the install, I noticed that when I try to open back up DVD files using iso mount and daemon tools, I get a blue screen error message. The weird part is, VLC player opens them fine, just not an actual DVD player. I can mount the files alright but when I go to play them, that's when it happens.
I updated my nvidea drivers so that's not the issue.
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?
