TV reception has noise flecks running thru' some channels. Has perfect reception in Win 8 Pro WMC. Tried changing Tuner cards, adding signal amplifier, rescanning signals, makes no difference. Currently I've saved an Win 8.1 image and reverted back to Win 8. Any suggestions ?
Resolved: Installed new video card instead of HD4000 internal graphics. Too early for updated 8.1 HD4000 drivers.
