Artifacts on the built-in video card?

Question

Video

I bought a new motherboard Foxconn G41MD , built-in video card.
So even when entering the BIOS, artifacts are observed: some characters of a different color (when rebooting, other characters have a different color), incomprehensible stripes on the screen. When working in Windows XP, the stripes remain, as do the dots in the form of a loop behind the mouse cursor.
I changed the mother in the store - the same glitches.
I put the simplest PCI video card - glitches disappear.
Has anyone come across? The computer should be given to the accounting department tomorrow, it would be decided today.

Answer 1

It is quite possible with a marriage in the series, but it is still worth checking the RAM, which, in particular, is also used as video memory in the case of an onboard video, for example, using memtest86.

Answer 2

Check your operating system. Try plugging in another one and check.

Answer 3

Perhaps a problem with the monitor or cable?

Answer 4

Since glitches remained after changing the motherboard, then the main options are 2
1) If you connect an external video card with a different cable, there may be a problem with the cable.
2) A variant with a well-worn power supply is possible, and an external video card is of better quality and this does not affect it.

Answer 5

Do you have the same motherboard on which the integrated video card works correctly? Possible marriage in a particular batch of boards. There was some kind of problem with Foxconn (I don’t remember which one now), I decided to replace it with a board from another manufacturer.
