I there , this machine was with the grafic chip dead , so we've replaced it with a brand new chip from our usual supplyer , we solder it and all was fine , client came back 2 weeks after , complaining she had a blue screen meaning something about AMD , and complaining she had a few red lines apearing on screen . when i turned on the machine i've noticed on the windows events ,a lot of logs about the amdkmdag , and also a few DISPLAY logs , meaning the controler had crashed but had recovered . tryed first , cleaning the video driver and installing a new one , but same issue , is happening . so tryed a clean install since this windows is a bit kinky , but even with new system and without grafic driver (AMD one) i had this red lines but small lines appearing like this size - - - - - - - -- -- - - - but not all screen only in few parts , i think it could be something wrong on the soldering process so reflowed it well , until meltdown , but he keept ok for one day without error logs . this morning was giving amd error logs and the lines appeared again .i will post a photo i found on google that is pretty similar to my problem !
my question is , i never had problems with does chips and supplyer , and sincerely i dont think it can be a chip problem , but maybe a Vram problems , what are your opinions about , and how can i chek wich is the faulty (vram/vrams)
cheers
