hi im trying to fix a pc but on start up it says 'hardware monitor found an error' go to power start up in the bios, so i go to that but dont say wot the problem is.
so then i load up windows and i loads but cant see the start button, and screen is thinner.
i have tested it with another power supply but still has a problem, could it be the motherboard?
i dont want to spend loads of money fixing it up.
my power supply has only 19 pins? and is abt 230 volts ( i tested it with a 20 pin cable but no luck)

its a
Sony VAIO PCV-RX406
P4

thanks
