Black screen on computer bootup

July 24, 2016

My computer wouldn’t boot up this morning. The lights were on, but the screens were black. I’d seen the manufacturer’s logo, but then nothing. No Windows login screen. Nada.

I tried a second reboot — same result. Then a third. No joy.

And then I saw that I still had my fancy Parrot Zik bluetooth headphones plugged in to a USB port to charge. Hmmmm…. Every time I’ve plugged them in, I get a message about a new device and do I want to open files, etc., so the computer thinks they are an external device. My husband has an external drive that won’t allow his computer to start up if it’s plugged in on bootup, so perhaps the headphones were the reason?

I unplugged the headphones, rebooted the computer, and everything booted up as it should. The headphones were the culprit!

Interestingly, I have an external hard drive that’s always plugged into this PC, but it’s ignored on bootup. I probably need to talk to my PC Guru guys to see if I can alter the startup sequence to look for the hard drive first, instead of any external drives.

Update 25 July 2016: I checked the BIOS boot sequence the next morning, and found that my hard drive is listed second, in front of USB storage devices, CD/DVD, onboard NIC, and the external HDD (last). However, ‘Diskette Drive’ is listed first (who’s used a floppy drive in the past 10 years???), so I’m pretty sure the PC thought the plugged in USB headphones were a floppy disk! Also, a quick Google search of “usb headphones boot sequence”gives many articles from others who have had this problem with various headsets/headphones.
