Gainward RTX 4070 TI - Black screen during game and switch on with pixelised picture

[Herken]

Hello community !

Since many months i havea big problem with my graphic cards, after some hours of game (sometimes 1 hours, sometimes 4) the screen switch off and switch on but after switched on, the picture is pixelised:

Drivers updated, mother board bios updated.
Windows 10 22H2.
New installation of Windows no affected (hardware problem?).

I purchased this graphic card on LDLC (french site) but they asked me to try superposition benchmark and the problem not occuring but it's not during enought time with the free version, i suppose.

What di you suspect? Graphic card? Power?

Thank you !

That PSU is plenty for that card.
Check with another monitor and another display cable and another HDMI/DP port on your card. One of those might be failing. Or test your card on your TV. If it's ok with them you should test the card on a friend's PC.

Hello @droopyRO ,

it's come again now, i disconnected the DP port and reconnect it and the image coming good again. It seems to be the port the problem, maybe... I will try with hdmi. Is it better to be in hdmi or DP for you? Is that a way to flash the controller?

Thanks!

Depends, if your monitor is running at it's max. refresh rate and full RGB then eithe DP or HDMI are fine. Just use another port on your card if one is faulty, no need for reflash.
