hey for quite some days now i'm facing a red pixels flickering prob over the dark parts sometimes. it doesn't stay for a long , but appears suddenly. specially when i turn on my monitor after 20-30 minutes.
so is it a monitor issue (i use a dell 24 inch or a mother board)?
i know the cable connected to the monitor (hdmi) is not faulty, cause i have changed the cable but nothing happened. the only thing i noticed that going from vga to hdmi cable partially solved the prob. the randomness of that prob reduced and they started to show on screen after 4-5 days, while with vga it was a daily prob.
again my gfx card isn't faulty cause when i unplugged the card and ran with intel HD graphics the same prob occured.
so should I change my motherboard ? or just call dell customer service?
thanks for helping in advance.........

That sounds like a problem with the monitor. I would call Dell as you suggested.

A faulty graphics card can cause video artifacts. But as you stated that it occurs with both integrated graphics and graphics card, that points to the monitor.

I don't think the motherboard is a problem.

thank you.
i have called the dell customer care service and they have said to send it for rma.
anyway just asking, how often a motherbaord gets damaged ? does changing the graphics card a lot can do anything bad with the mobo?

You can damage them with a static charge. But if you are careful to ground yourself to the PC case, you should be fine. And a surge suppressor will help with preventing some of the electrical surge damage.

Motherboards do get damaged occasionally. There are quite a few here on this forum, but of course they come here to help them with their problems.

dat means mother board doesn't make any display prob! dats quite satisfying.
cause i don't want any trouble with my sniper m3 mobo. its pretty expensive.
and if its was dat , what u said. then with a damaged mobo pc won't even start i think.

In this case the motherboard is probably fine. The easiest way to test it is to swap out the monitor with a working monitor. The try to reproduce the display problem.
