    so, old computer bits been recycled to nephew. had problems booting, cpu swap did nothing so figured was mobo, bought new one and boom booted and had been working great.


    it seems that its now gone back to not booting properly. they turn on the power and the fans all light up but monitor gets put to standby.

    does this mean its the gpu dying? this is similar to what was happening to me before and a gpu change never helped any.

    could it be a wonky psu having killed the onld mobo and now killed the new one?

    i have to leave the county at the end of the week so time is pressing

    Bad PSU can kill any part, so was that also some old cheap PSU?

    if i recall, it was a 430w corsair.

    however they brought the thing to me today an it powered up fine so it seems as if crisis over and its working.

    balls, so its doing it again. its not posting. swaped the gpu no difference and it can be ram as it wouldnt have been working fine when posting, this is just like before with the previous motherboard.

    i had tested another cpu with the old mobo and was doing the same so the only thing left is the PSU, is it possible the psu could cause the mobo to fail to post but otherwise powerup all the fans? im running out of ideas

    is it worth me buying another psu to try in it?

    I've run into thus before and it was because of my ram not being seated properly
