    Default PSU fan died now Computer won't start

    Hi, I have only a little experience with computer hardware but I was capable of replacing my PSU fan when it died. My computer wouldn't start and I found that the PSU was difficult to turn by hand. Now that the fan is replaced my computer still won't start. The keyboard flashes when the PSU switch is turned on. When ON the DVD opens/closes, both PSU and CPU fans turn but monitor stays black. There are no beeps. I have an old computer/monitor lying around so I was able to test the cords (they are fine).

    The computer is a Pentium 4 that a friend set up for me. I was running Windows XP. The PSU is an EZMAX YH-480W (115/230V 8A 50-60Hz)

    I was going to replace the PSU, but I wonder if it's the motherboard since everything seems to be getting power. I checked the 4 pin and 20 pin connections to the motherboard and they are seated fine.

    Could it still be the PSU and do I have to replace it to tell for sure?

    Thanks

    Hi Creeping Doom,

    Since the fan jammed up on the power supply unit it's possible other internal damage could have occurred too. I think the most logical thing to do first is to swap out the entire power supply and then see where we are at that point in time. Good luck!

    I figured as much, but I thought I'd check to see if it was something else. I'll go grab a new power supply tonight.

    Thanks for your amazingly prompt reply.
