This is an old Dell latitude e5510. Spilled something on the keyboard. Thought I got it all off before any damage occurred. left the system alone for a couple of hours came up perfect. Walk away for a few minutes and returned to a blue screen with a white bar flashing in the upper left corner. Tried to reboot several times. Dell screen comes up with f12 option right top. At first I got the f12 screen and reboot options, but all took me back to the same blue screen. Now I press f12 and it goes directly to the blue screen.
All my data is on this system I have to get back in, please help. Not technical, but can follow clear directions. I cannot sleep until I get this thing started.
