hey guys and girls.

problem= this computer has worked perfectly since new the power is turned of at the wall after shut-down but when i turn it back on at the wall it decides to boot up on its own. and the monitor does not kick in to life.
but if i then hold the power button down to force a shut down and then turn it back on it starts up normally and the screen comes to life.

i have changed the POWER UNIT and the CPU fan in-case there was something wrong with either and have still got the same dam problem i have run a few diagnostics but have come back blank?

any help or information on this would be great.
if you need the pc spec's please post on here as im currently at work and don't have them to hand

thanks again guys n girls

Have a look at the capacitors on the motherboard to see if any of them are bubbled up and/or leaking. If you find any like it, you will need to replace them!
