Can anyone suggest what key combination I need to hit to access my PC set up at boot-up?

I used to know, but havnt done it in so long I cant remember.

Give us the make they are all different

I presume you are seeing nothing in the top right hand corner of the black screen before Windows starts loading. ?

The use of the delete key {Del} to enter the setup program during boot is becoming standard. AMI and Award BIOS, and some others as well now use this. Older BIOSes can use any of strange key combinations, including Esc, F1, F2, F10, Ctrl-Esc, Alt-Esc, Ctrl-Alt-Esc, Ctrl-Alt-Enter, Ins or others. If one of the above key sequences does not enter the bios setup program, you will have to seek out a manual for your system

Pressing Delete as your computer is loading will bring you to the BIOS setup screen.
Is that what you're after?

[Impret-Sir]

Yes bobjim, but I have tried delete, it didnt work. Sarah_louise, its a five or so year old Tiny PC, im not sure who the motherboard or the BIOS was actually made by. I will try the combinations you suggest. I have already tried all the F keys without success.

You could try pressing Delete repeatedly and rapidly as the system starts up. If you only press it once or twice it often doesn't get recognised. I think it's something to do with today's processors making the system shift through its startup routines so swiftly that you can easily miss the window of opportunity to press Del and have it acted upon. Just keep tapping on it during startup. Might work...

You may need to be quicker, especially with a fast booting PC. Doesn't it say on the screen as it boots up (sometimes the monitor doesn't warm up fast enough to display all the messages).
Del or F1 should work in about 80% of cases. Press them alternately and repetitively from the moment you hit the "on" button.

Thanks everyone for your answers, I will try all your suggestions!

Press any key and keep it pressed. The PC will think your keyboard's knackered and offer you a chance to ener bios setuo.
