does any body now why, when i was working with win xp sp2 so normally i pluged the power suppy to a sata disk ( i didnt plug the data bus cable, only the power supply cable) a blue screen of dump of physical memory appeared, i suspect is the PSU the one who isnt giving the necessary wattage, am i rigth?
 
Normally I would say power supply

But if you plugged the sata drive power in when the computer was on, and in Windows, then it may have been the powersupply adjusting for power loss, and momentarily causing your main drive to crash. All computer parts are sensitive.

So I'm not sure if it was just a quick adjustment to a loaded harddrive, or the powersupply faulting.
If you plug the sata in whilst the computer is off, then turn on the computer, does it blue screen then ?
If so, power supply fault.
 
Ok, i cheked it and its keep doing the same blue screen, only when i unplugged some other devices as CD dirve, and some pci cards and it worked, so, i think im replacing the Power source

Thank you very much

Just to double up on that

Please reply back - one day - when the new power supply is fitted and working.
