I have fixed a friends Dell Optiplex 745 computer. All is working well except it will not boot directly to windows, I get the "press f-1 to continue then it boots up. When I go to the bios, it looks different than any bios screen I have seen. I don't know how to fix things there, there are not a lot of options..In the BIOS you could select "RESTORE defaults" and that may get normal operation back. Does the "F-1" warning contain any INFORMATION as to what is prompting it such as a fan failure,etc.? truenorthSounds like the F1 to continue is just telling you the system checked out OK and is ready to boot. Some MOTHERBOARDS have this setting in the BIOS, and it could be the default setting. I would SEE if you can look around the different BIOS menus and see if you can find something that sounds like this option. You will not change anything the BIOS unless you select the "save and exit" command when done and then confirm it again. Just looking around doesn't hurt anything, and if you don't save any changes when done in there, that also won't hurt anything.
