Re: Are you sure?
I once plugged in an ISA card while the PC was running. I want to say it was a Sound Blaster AWE32
20+ years ago I was working on my powered on home PC, probably changing a fan or something on the go. A screw fell and landed on my AWE32 and killed the left channel permamently. :'-(
On another occasion (20+ year ago as well) I had a work computer without side panel because I was often testing different hardware with it. I inserted an Adaptec PCI SCSI card and hadn't noticed that the computer was on (noisy area, monitor sleeping), so I was amazed that Windows 2000 noticed a new card and started installing drivers without any problems.
Later I tried hot removing the same card to see what would happen and a BSOD ensued immediately.
