Roxio is the CD burner software. Who knows what happened, but with Vista all things are possible.
Dump Vista.
It recently took me three days to figure out a small button on the bottom of my mouse was preventing me from using the taskbar. Actually there are three buttons which push, switch and flick. I don't don't even know what they do nor which one was the problem.
Stop Roxio from loading at start up and see if you still have the problem. That dll maybe shared by other programs if I recall.
Weird it would blue screen and shut down.....sounds hardware related.
Do a web search on ‘px engine blue screen’ and you’ll see that others have had this problem or similar. And on more than Vista.
You might want to use a different program to burn CDs.
Am currently running O(bama)S(oftware) Version 08, never have a problem as my computer doesn’t work at all and my bank account is always full of other peoples money...
I happened to notice that there was a hardware upgrade for my Dell monitor, so I included it in a round of custom updates..
all hell broke out after that - blue screens, conflicts, errors, “reload windows” prompts - somehow I got it to boot into safe mode and backed out of the update...
moral of the story - if it’s all working, do not upgrade hardware or firmware....
