Random red pixles on laptop screen

[chea1337]

So I have a msi gt70 2pe laptop the motherboard died so i replaced it (ms-17631 REV: 1.1) it works fine but since I started it up for the first time I have been having red pixles randomly appearing and disappearing on the fly...and it only does this on the laptop display I plugged in an external display and it doesn't do this on the other display only the main display.  so I thought it was the display connector I checked it was fine I even wiggled the connector to see if the pixles would stop flicking or change picture and no change so thought it would be a faulty bios I checked it it has the latest bios: E1763.ims.11D for that motherboard so I checked the vbios: 80.04.F7.00.07 it was up-to-date so I re-seated the gpu and heatsync still no luck so I thought it might be thermal issues but I can say I've have it happen when the GPU is at 60c or 91c and on desktop 2d mode or in game 3d mode so I'm kinda stumped on what to check for next...it hasn't had this problem before I replaced the motherboard so I did some research and found out most likely my motherboard may havecame from a msi gt70-20c/gt70-0nc/gt70-2pc/gt70-2pe so I've looked into everything I know about computers and have no luck...also my quick launch touch bar also stopped working after I replaced the motherboard no turbo fan or nothing...also I've replaced the wifi/bluetooth card from original one to atheros AR9462 AR5B22 because I broke the original one but I don't think this would cause an issue..so if anyone has any ideas on what it could be a replay would be awesome..my system specs are (msi gt70-2pe with i7 4810mq and gtx 880m running on ms-17631 REV.1.1 motherboard)
