No problems at all with Win 7. It is very fast, and has lots of nice features. XP will not be supported much longer, and after using 7, when I go back to the laptop with XP, it seems clunky!

Agreed, DonM

Mine starting doing that and it turned out to be the HDMI cable.

That is the second HDMI cable to go bad for me - one on the TV and one on my Win 7 PC.

I have seen on the net that the HDMI cables frequently go bad.

My wife's is wireless, so cable is not the problem.

I rathered my Vista Home Premium to this Windows 8. I shudder every time I think of upgrading to 8.1, scary!!

... Win7 is on my desktop PC ... no changed wires, no loose plugs ... nothing out of the ordinary other than that it shut down ...
Lydia is using Win8 on her lap top ... took some getting used to but it is working fine ...

Tony, with all the heavy power usage around this time of the year, you may have had a momentary brownout that you didn't notice. That COULD cause it to reboot. Just a thought.

It was probably a momentary power outage which will cause a computer to re-start.

NOTE: if it went off and came back on after a short time as it was (Did not re-start or shut down) then it is probably a hardware problem, which will take more diagnostic investigation to identify, however giving all the fans and grilles a good clean will probably help. (Most case fans have filters which can get blocked)

Hope this helps

Thanks for all the suggestions guys ... perhaps it was a power supply thing ... it TOTALLY shut down and then came back up without restoring the screens I had up at the time ... I will keep tabs if it happens again ...

I have my home computers always on a UPS power back up. Not only does it have battery back up it also filters my AC power before it gets to the computers. My power is very "dirty". The UPS beeps often indicating power glitches and sometimes I see drops under 100 volts. Thank you Florida Power and Light!! (Better known as Florida Phlash and FLicker!!!!!!!! ) -charley
