V5 571 does not get to POST, keyboard flashes and fan starts then nothing.

I have a two year old V5 571, a week ago it stopped booting up when I pressed the power button. There are no beeps and the laptop doesn't boot as far as the POST screen.

 I've tried with battery and without and taken out the CMOS battery to reset it but still have the same problem.

 

 As it's only two years old I would hope the motherboard hasn't gone.

    Can be also bad ram sticks and faulty HDD.

    I've tried it without the HDD but not without the RAM, fingers crossed.

    Tried it with no RAM, things start to happen but of course with no RAM nothing much is going to happen.

     I've tried one stick of RAM, two sticks of RAM, swapping them over and a spare stick of RAM to see if it made any difference.

     

     Where do I go from here?

    so with one stick or swapping them, you can't still boot to BIOS pressing F2?

    No, I'm afraid not. I don't get the flashing keyboard any more so that is progress of sorts but still no POST.

    Try to boot to BIOS pressing F2:

    without HDD and ram sticks installed.......FAILED

    without HDD and just one ram stick.........FAILED

    without HDD and swapping ram sticks......FAILED

    after clearing CMOS..............................FAILED

     

    Probably the mainboard is gone.

    IronFly covered most all, but i wonder ? 1. boot to flash BIOS, might be corrupt 2. BOOTABLE media. you need at least some memory. that by passes the HDD and OS
