|Sounds like it may be a mixed die off. Most systems i have seen (old ones at least) have the pwr button hooked to the PSU directly. The newer (2007+) computers, however, I have yet to open one up. I have no idea how those pwr buttons work BUT if I assume they may hook through the MB. The fan means you still have 12v most likley. Try plugging in the power then plugging in a USB device (thumb drive, MP3 player, etc.) into the computer. If it has a little light and it lights up, means you have 5v too. Then you probably have a bad MB, and not PSU. There is a limited amount of diagnostic work we can do from here though. At this point, you might want to find someone in your area that knows what he's doing inside a comp case (preferably without pay) to get your HDD out and copy/wipe it, put it back in, then you can take it back to whereever you got it from and complain.|
P.S I forgive you for being a noob, not everyone can open a comuter case and find the problem in 8 minutes ;-)
EDIT: Yeah, what did you plug directly into the power supply? i'm having a ard time fol.owing you.
