    My Alienware M15x laptop is not booting up, when I try pressing the boot button, the keyboard lights up, I can see the CPU fan running following by the GPU fan too but then all the three lights - Scroll Lock, Caps Lock and Num Lock keep on blinking. The fans stop and nothing happens.

    I tried removing the battery, draining it but it didn't help. Also removed the coin-cell battery and plugged it back but still the same issue persists.

    I checked out the following link

    Alienware M17x R1, R2 and M15x LED Behavior Prior to Proceeding with No POST troubleshooting | Dell

    which says

    A system board component is faulty.

    How can I confirm this - also how to know whether the issue is with GPU or CPU or any other component?

    Any help would be very much appreciated.

    Have you recently changed anything in your laptop? Try reseating cpu/gpu/ram.

    I was doing some photoshop stuff for the past few days, so as expected CPU was running at its peak.

    Day before yesterday evening, after completing some post processing, I had shut down the laptop and then when I tried booting it yesterday evening, I had this issue.

    No changes to the laptop in the past few days, a month back when I was planning to upgrade to SSD, I did perform a trial(opening the case and removing the hard disk) to get comfortable with the hard disk change, but I haven't bought a SSD yet.

    The laptop is 2 years old, have upgraded the RAM an year back, so no other changes have been done to the laptop since then.

    Once I get home today, I will try reseating cpu/gpu/ram as suggested.

    It could be that.

    Have you tried one memory stick at the time?
    CMOS clear
    Power drain
    A different video card?

    Fixed it finally, I didn't go the extent of re-seating CPU & GPU.

    I tried one memory stick at a time and also tried removing the CMOS battery once again which fixed the issue.

    Thanks everyone for your support, very much appreciated.
