But if there are loose parts inside the PC like you find in many clone jobs I'd only do that with the power off when I want to clean the machine.
The BSOD is a safety mechanism to stop damage to hard drive content and more. It's not a bad thing really.
Hi, just a moment ago I was opening the side lid of my computer to clean the side window of it while the computer was on.
About 10 seconds after removing the side, I look over and see the blue screen of death.
So my question is, was that blue screen of death caused by me opening the lid of the computer and something screwed up some how? (doubt it but maybe.)
