This is the case at first start...and also at restart, when computer is 'warm'!!
And when it boots succesfully it keeps running without issues?

First check for newer BIOS update on computer or mobo Support Downloads webpage for your model. If none then Clear CMOS - 3 Ways to Clear the CMOS - Reset BIOS

Then work through these steps for Troubleshooting Windows 7 Failure to Boot - Windows 7 Forums

Have you ever flashed (updated) the BIOS on this motherboard?
Is this the PC listed in your system specs section?
Do you have more than one monitor connected to your video card?
If your motherboard doesn't have an onboard PC Speaker it might be a good idea to connect so you can hear the BIOS Beep codes.
Are you pressing the correct key to enter the BIOS?
Is your keyboard wireless, USB, or PS2?

Try adjusting the Screen Resolution and/or updating the Display driver for the HDMI plasma TV.

If necessary, unplug it and use a VGA monitor to see if it stablizes.

Then add the HDMI and find a driver or Screen Res which stabilizes it via optional Windows Updates first and then the display device's Support Downloads webpage.

.....can't help feeling I'd be going down the wrong track here.

The bootup problem first occurred 3-4 days ago....until then, all was sweet as a nut!!

How is assuring you have the latest driver and best screen resolution a possible wrong track? These are best practices to begin with.

If you know when the problem began then try a System Restore point just before then.

....so the screen resolution, and driver generation, can be responsible for the symptoms described in post #1....??????

With a 50" HDMI Plasma TV connected, yes.

Unplug the plasma display from the HDMI and see if you then get your BIOS post screen on your monitor. Or turn the TV on and see if the BIOS POST screen shows up there. I don't think you can get into your BIOS using a wireless keyboard. You'll have to use a wired USB or PS2 keyboard.
