I was having problems with my floppy drive, I opened my machine and fixed the floppy issue. But now I seem to be having a power issue. My computer won't come on. I unhooked all the power cords from the components in my machine, but left the motherboard power hooked up. Then tried to turn it on. Now the thing is when I try to turn it on all that happens is my power supply fan turns a little bit an makes a squeaking type noise. I thought it was my power supply that was the problem, so I wen't out and bought a new power supply. But that change nothing. Now I'm clueless as to what it could be. Does anyone have any pointers to share?.
