For the computer ask for f1 key to start

Its asking you to Press "F1" key because may be its having a hardware problem,

which should be checked or need to adjust the settings in BIOS. It also an

indication to replace the CMOS battery.

Try this 1.

Go to your BIOS and load default settings. Also check the date and time in BIOS.

If you don't have a floppy drive then Disable the Floppy Mode option in BIOS.

Look for the option "Halt On" and set it to "No Error".

Save the settings and exit from BIOS.

If the problem still exits, change the CMOS battery --> Go to BIOS and load

default settings --> Make sure to disable the floppy mode if you don't have a

floppy drive --> Set the first boot device as "HDD" and save the settings and

exit from BIOS.

Good Luck.
