ok, something reallly weird just happened, i decided id try to connect BOTH of my hard drives at teh same time and run my new one as boot one, one doesnt have a jumper and the new one is set to CS (cable select) anyway, once i booted up, both drives started up, but then i see that the Bios doesnt detect either one!!! so i shut of the comp and try again, still nothing, i unplug the old one and wala, it worked. so maybe it isnt a PSU failure after all, but a mobo issue? i also got an idea, what about the IDE cable? could that be it? mine seems to be pretty crimpled up.
