Strange glitches on the screen Lenovo Z51-70

Hi,

I am happy user of Lenovo Z51 laptop which works fine just some time ago screen started to show some strange flickers when computer is working. They are best seen on white background of browser but they also appear while I'm looking at desktop. They appear and dissapear after a second, I found that they tend to show up in larger numbers when computer is under higher stress (like gaming or doing some calculations). 

 

Here's the photo, I managed to make a screenshots when those flickers are visible: http://prntscr.com/bj4xxo

http://prntscr.com/bj5632

I'm using WIN 10.

 

Any ideas?

Hi Walt27 , 

 

Welcome to the Community Forums. 

 

As the screen show more of the "=" marks on your screenshots , check if the same would show up on an external monitor as this manifest as GPU issue. 

 

You may also try to run in safe mode to check if the display would do the same. 

See if the BIOS and driver are updated from the support site

 

If same issue goes , run the hardware diagnostics and temperature test for isolation. 

 

Update us as it goes. 

 

Regards

Thanks, I don't have possibility to plug external monitor at this moment so I am going to try diagnostics.

Temperatures are okay, while on standby they are between 40-50 celsius, also I am using cooling pad.

I am using Driver Booster 3 to manage drivers and seems they all are updated.

I think this is video card issue, while lenovo solution center tested video card on high stress, flickers covered whole screen and stopped after the test:

Diagnostic showed error with integrated intel graphics card:

Should I contact support?

Hi Walt27  , 

 

Greetings. 

 

If even after updating both drivers directly from Intel and AMD would fail , best to call in technical support so that they would be able to decode the error message and provide needed recommendation .

Set expectations for doing your back ups and possible repair service as needed.

 

Our diagnostics may have just answered the reason for the glitches on the display. 

 

Regards
