just looking for some feedback if it is possible to get a power surge through your cable modem (usb ,or ethenet connection) and fry the motherboard and or processor.
Your cable should be grounded at the point of entry into your home to prevent a severe surge. I'd be more worried about the TV or cable modem itself than the PC.
If you are really worried about it, you can buy a surge protector for coax.
ok thanks. even if that is true can a surge still wipe out the motherboard and or processor.
A surge is still possible through your cable line even if your outlet is grounded. I live in Florida and have to replace my cable modem 1-2x a year. I haven't had a surge damage anything other than the modem (connected via ethernet) but my cable lines into my neighborhood are also buried so they are not prone to direct lightning hits.
