    PC help required

    Son has built his own PC but it turns off after 25 seconds then turns on again. This keeps repeating. Any of you techy types got any ideas?

    Do you see anything on the screen? The sequence of beeps at the start will usually tell you what is wrong too.

    Same with the graphics card. But yeah how many beeps is the motherboard giving on boot up? Does it reach BIOS?

    Nothing on screen at all and no beeps.

    You say he built it himself... I assume he applied proper thermal paste to the CPU and cooler? The boot cycling sounds like a heat failsafe to me.

    Could be. If that’s good then check everything is seated properly. Most good coolers come with decent paste pre-applied these last days though.

    The motherboard should have come with a small speaker which does the beeps IIRC, did he connect it?

    Assuming the cpu is seated correctly (worth checking) then you will always get beeps.

    It has paste already.

    I'm not sure everything is seated properly and I don't think a speaker is attached to the motherboard. I'll check today.

    Thanks all.

    Has it got far enough to have an OS installed?

    No.

    He's just run it without the graphics card and the memory in every combination and no cigar. I've told him to start again from scratch.

    Other than giving everything a good clean, I've no idea.

    I’d build it outside of the case first off and see if you can get it working that way.

    Is he 100% sure the CPU is compatible with the Mobo?

    An IT bod checked his stuff and it's all compatible. Might be a dodgy part. We get no beeps unfortunately.

    Thanks again all.

    He's reassembled it and now it stays on. No signal to the monitor though.

    Make sure the monitor cable is plugged into the graphics card rather than the motherboard.

    I've made that mistake before.

    Or take out the graphics and see if you get a POST when connected to the internal graphics.
