I have a rack-mount PC which has a Seagate 160GB SATA drive in the unit. This PC has a very sturdy case and the rack is grounded.
I placed a very old Panasonic 9″ black and white security monitor on top of the PC. (basically an old TV)…it weighs about five pounds or so.
With the monitor on there, powered up, the PC would not boot. I moved the monitor and PC booted right up.
Coincidence?
Wrong alignment of moon and stars?
Time to buy a spare HDD for that PC?
Don’t put old video monitors on PCs???
