Ot - computer won't boot

[Phil]

I don't know if this will top-post or not, it's the first time that I've repied to a post with this tablet. Anyway, thank you for your replies
I have more thoroughly tested the power supply and all voltages are present and within spec. There are no beeps from the computer and there is no video so there aren't any fault messages. I have unpluged both the hard drive and the DVD drive just in case. I have connected the computer to the TV hdmi port in case the monitor is faulty. I have not located the reset link for the bios yet. It's a crowded ITX board.
So, it looks like I may need to seek professional help (as some unkind people have suggested). Just how I might do that, because of my remote location, is unclear to me at the moment.
I'm thinking that a replacement laptop might be the best solution.

Are there any beeps, when powered up? If yes, check motherboard manual
to decode them.

Disconnect all hard drives, CD drives etc. Try booting and see whether
you still get "no bootable device" or alike.

Find the BIOS reset jumper on the motherboard. Reset BIOS.
