Gigabyte B75M-D3H black lines

[cottonswab22]

Hi I have a B75M-D3H mobo with a G540 processor and 4 gigs of ram.I am running windows 8 for now.
Anyways at a high resolution or highest resolution(1280x1024) the intel graphics will show black lines or bars all over.At the lowest resolution 1024x768 I will get a black bar on right side of screen.
I even get the small black lines when in bios.I have updated bios to F11.What could be the matter ?
I have a Dell VP171b monitor.

look in the bios for igpu memory freq and try reducing it slightly or increasing the igpu core freq voltage by one or two clicks,their might be an option for igpu memory voltage and try one or two clicks more

you can also increase how much system memory is dedicated to the integrated graphics

Sounds like something is overheating or OCed to much. +1 with Wazza300.

Thks for replies guys, I'll try those igpu settings.
Graphics dedicated memory is at 64 should I just do igpu first and see I already tried 96 and still same.
I have no overclocking ,cpu temp is at 26-27 c.
Even the bios layout has small black lines.

Also having trouble with uefi bootup.Should first boot device be windows boot?
Then hard drive ?
My first time working with new uefi bios.

Windows 8 keeps having problems at startup and I have had to do a systemrestore a few times.
I have my sata hard drive connected to sata port 1 on board and sata dvd on 2.

THks

Humm after that reply one has to wonder if you have a bad flash to UEFI bios, boot order should be definitely windows boot device and or windows 8 OS.

Do a web search using linux diagnostic live cd
You don't need to install Linux on your system, just boot from an optical drive.
You can run stress tests from Linux, including graphics tests.

Mobo was RMA from where i bought it online.HOpe that was the problem.It could not get the internal graphics up higher than 32meg which is the lowest.

A bad flash is not the problem ,it was doing that before the flash.I was told to update the bios and that did not work.
I am still waiting for Gigabyte to get back to me I sent a support ticket through there site last week.
Where is tech support for Gigabyte?
Phone numbers and what else I mean.
