PC crashing after unplugging DVI cable

post #1 of 8
Thread Starter 
Today I used my PS4 on my PC monitor, so I disconnected the PC's DVI cable and connected the PS4. Some time later when I plugged the PC back in I found it had crashed as nothing was displaying on the screen. Is this normal? Is there a way to avoid this happening, or will I need to turn my PC off before connecting the PS4 in future?

Always turn the computer off before disconnecting cables like this. The only real safe cables to unplug while the computer is running are USB cables, ethernet cables, audio cables, and other extremely low-power cables like that (but I wouldn't do internal SATA cables or any other internal cables). Higher-powered cables like monitor cables shouldn't be touched until the computer is off. You probably didn't see or hear it, but there was probably a little spark of ESD when you unplugged the DVI cable.

While it's sometimes possible to hot-swap DVI and HDMI cords, it's not recommended, and your computer crashing would be a good example of why not to.
APU what?

Right I see, wont be doing it again in future then!

However, would this still be an issue if the PC was put into sleep mode? Or would it need to be shutdown before the cable could be removed?

That's OK because the HDMI port is powered down.

I'm not sure. Unfortunately, I don't have a spare computer to test it with either. However, if your sleep mode completely turns the computer off and just leaves the memory powered up, then I would guess that it's safe because the video card seems to be completely off. However, I would be scared to take a chance. So instead of Sleep Mode (even if it turns the computer completely off), I recommend Hibernation. Hibernation turns the computer completely off. It's identical to shutting the computer down, only you'll have a Hibernation file in the boot sector.

It's a computer!

Not sure if related, but I have had cases where the computer display output doesnt reinitialize correctly after coming out of sleep mode.
