video card turning off amd on

[jimIsbell]

This computer is NEW.  Two weeks ago I sent my invoice to them and they were supposed to "reset" the waranty.  Didnt happen.

But that is a minor problem...maybe....The problem I am having is that the monitor blinks off for 2 seconds and then back on in a seemingly random fassion.  It is so bad that I cannot communicate on it thru the "noise" as it hurts my head!!  So I am on my old computer now Monitor is fine now but if I cannect to the new computer it blinks.  This is obviously NOT a monitor problem.   suspect its a "settings" problem. 

It looks like it is going off to work on something else and turns off the video when it leaves, turning it back on when it returns two seconds later..

Sound like a bad connection but check your power and sleep settings

Set screen to "never" just to see if that makes a difference.

If problem still exists then we need to see if the motherboard has a problem.

For  motherboard borrow a VGA cable and connect to your monitor and see if the problem is still there.

If VGA works then get a magnifying class and sufficient lighting and look for debris in the HDMI port.

Otherwise contact service

Please contact HP support for service options

The solution has been found,....maybe......

Yesterday I got a notice that there was an upgrade waiting to be installed down on the lower right of my screen under "new notification".  I figured, "what the hell, it probably wont hurt."  I installed the upgrade and the flashing screen went away!!!!  I hope it doesnt come back!
