HP Pavilion 24-b212na. I now cannot switch my desktop on without first unplugging it from power supply and rec-connecting. I have replaced the power lead (with transformer) twice- not cheap, bought from a computer shop- without curing this problem. Any ideas please?

How old is your computer? Is your HP warranty still in effect?
Since you have changed the power-supply, without a solution, the most-likely cause is a failing motherboard.
HP may sell you a replacement "original-equipment" motherboard -- probably at a very-high price.
It may be time to purchase a new computer.

If you've replaced the power brick, then there's not much else you can do without replacing internal parts.
If it's still under warranty, then log a hardware warranty call. If you're in Australia, and it's outside of the 12months, cite the Australian consumer law. This should still get you a warranty call.
Otherwise, you'll just have to accept it as a new feature.
It's cost prohibitive to buy parts from HP to repair this unit.

This PC is an All-in-One -- and runs on DC current. The "transformer" is precisely that -- it is the same kind of power "brick" that laptops use.
I replaced one of these for a 4-year old AIO a few weeks ago, but it only cost me $30 USD -- so that's not a lot of money to get the PC working again.
