today I got this message when I tried to start my computer. (Windows 8.1 OS)
LogonUL.exe Application error
the instruction at Oxbf1985ef referenced memory at Ox00000014.
The memory could not be read.
Click OK to terminate the program.
I never get to logon....it doesn't get that far. Instead after clicking OK a small rotating disc comes up and my mouse can give an arrow. Doesn't matter where I put the arrow even outside of edges...no help.
Rotation continues and screen loses intensity of dark bluish color and gains and loses and gains. Rotating disc continues all the while.
I have tried what some other thread suggested Pressing f5 and f8 and right shift key and f8 multiple times.
I have tried closing the computer and trying to start again, several times.
No luck. There is no disc for booting that came with the computer (an HP 14r032TU) and I wonder what else I can try. The computer is 8 weeks old.
