    There is no way that is system memory related that is a graphics controller problem or video signal problem.
    Does it look the same in windows or is it just in boot?

    Demand they replace it... now. Threaten small claims court if you have to.

    You are aware that most on-board graphics chipsets steal memory from the main system memory.

    It is not unknown for onboard graphics to fail. I have seen many cases of the above being bad onboard chip, connector or cable. I have never seen bad RAM produce that, blue screen would happen if the ram was that corrupt, also it would be more intermittent with RAM where as this seems to be happening the same each time it boots from the sounds of it.

    Yes, and you would have a bluescreen at some point rather than a consistant video corruption.
    As you said it is system ram so you would expect additional system problems.

    The chipset may reserve the last xMB of memory , which would mean that the ram ( especial on a 2 or more stick system) may not be addressed by the O/S for some time. There may also be ram timing issues or other access issues between the GPU and RAM that are not affecting the running of the system.

    It is however an issue for the vendor to rectify.

    I would stick the monitor on another machine and visa versa
    If it happens on the machine you changed monitors with, it is the monitor.

    If the original machine does the same with a new monitor it is the PC.

    That should be enough Diag to be honest as the fault is intermittent and they presumably don't supply diagnostic software.

    It's easy enough to try RAM from another machine... There is no way in hell it's a monitor problem because monitor controllers are not capable of outputting that on their own or misinterpreting what comes from the graphics controller/system in that state. Onboard GPU could of course be faulty - if it's an Intel though, it's highly unlikely to be that.

    I can't understand why everyone is trying to swap out components of a brand new machine that doesn't work. It needs to go back. It's not up to OP to work out why it doesn't work, he just has to have the evidence that it doesn't... and the photo he took is pretty clear.

    I cant agree with that, they covert signals they are more than capable of doing that, a bad connection, dry joint could easily cause it.

    It is reasonable to find out if it is the monitor or the PC on a new machine, it is not changing the memory IMHO. Especially when they could accuse the OP of damaging it.

    I'm more aware of the signal processing capabilities of monitors than many would imagine. I do agree with you @elsiegee40 but it depends on the individual IMO; it's a 2 minute job and all of our suppliers would be happy to accept our diagnosis and arrange return/supply of replacement parts. Something you may already have some of, and lessen the involved downtime.
    Some suppliers may be less happy about it though; in all honesty it sounds like yours might be one of them. Keep shouting at them.

    No, I supply them. Just that we supply ones with Diagnostics SW.

    I agree the mem is an easy job, but on an intermittent fault I would rule out the external factor first (monitor and cable). That is the only bit with a seperate warranty I presume on his PC's (Monitor warranty is usually direct) if he can rule that out he can just boot the PC back at them for them to sort out without delving inside.

    On a new build it should be treated as a DOA IMHO.

    Agree with above, swap monitor and cable for known good items and if it still doesn't work get it fixed under warranty.

    It's not your problem to diagnose or worry about, if it doesn't work out the box get the manufacturer to sort it.
