  1. I posted in these forums about 3 weeks ago becuase my computer wasn't powering on. It just flickered when I hit the power button and then died. only the led fans lit up, for a second, nothing started spinning.

    I've tried EVERYTHING with my old mobo and psu, including shorting out the pins, resetting cmos, unplugging HDD, etc, I'm pretty sure i did literally everything to try and fix it.

    I bought a new mobo (p5n-e) and PSU (rosewill 550w) to replace my previous components (p5b and FSP 450w) first I got the new mobo and plugged it into my old PSU, that didn't work, so I figured either my PSU and my mobo were both fried, or my PSU was fried, so i got a new Mobo

    Perhaps the CPU is the next potential culprit.

    why would my CPU be fried? I've heard of other people talking about it, but I don't really have a different CPU to try lol.....

    is there a way to check that?

    have you "table tested" your hardware prior to installing everything into your case?

    try with only the minimum components:
    • PSU
    • Mobo
    • CPU/HSF
    • 1 RAM stick
    • video card (unless mobo has integrated video)
    • HDD (format if necessary)

    how about replacing the PSU? That should have been the first thing to replace.

    I'm sorry to sound rude, But I have clearly stated that I replaced BOTH by Motherboard and PSU prior to posting this thread, so that really sounds rather silly for you to suggest....but thanks for trying to help.

    I have done that yes, but it did not help.
