Hello!
This computer runs Windows 10. It was booting fine until a couple days ago. Now when I try to boot it goes from BIOS, to the Splash Screen, and then the circling White on Black screen, then a circling small blue sand dollar, and then eventually to the error message
"LogonUI.exe-Application Error. The instruction at 0x00007FFC83D2A263 referenced memory at 0x0000034600000445. The memory could not be read."
This whole process takes about 30 minutes.
I have tried reseating memory but that did not help. I have tried RAM from another identical computer that is booting and that did not work. Thanks for your help!
