Reformat Hard Drive?
Your CPU apparently doesn't like what is going on and so your OSD
is turning off (freezing: software/memory bad).
A simple remove/reinsert on mouse should indicate if the "mouse was lost". In that case, you need to install a feline to catch it.
If that is the case, I would recommend installing a Margay
; not only will it go after your "mouses", but also rats, scorpions, bats, roaches, etc...
Worst case, your CPU is already fried.
Plug hard drive directly to Windoze® and see if it is recognized.
Have you tried with Hard Drive disconnected???
