Hi all, as the title suggests, my classified started lately, when i turn the pc on to tun on only 2 out of the 5 led lights.
 
the PSU seems fine also the motherboard.
i have contacted the support as well but i was wondering if there are any advises about this?
the card is 1.5 years old.
thanks
M.
P.S worth mentioning this doesn't happen all the time , about 3 out of 10 power cycles.

    Hello and welcome to the forum. Have you reseated the GPU and your power cables on both the PSU and the GPU?
    These 5 LEDs are voltage indicator lights that can help you diagnose voltage problems with your video card. With the fan facing towards you and the power connectors facing up, the LEDs are, from left to right:
    GPU - This indicates if voltage to the video card's GPU is good
    MEM - This indicates if voltage to the video card's memory is good
    PLL - This indicates if the voltage for auxillary components such as fans, LEDs, etc. is good
    3.3V - This indicates if the voltage supplied from the motherboard via PCIe slot is good
    12V - This indicates if the voltage from the 12v input from the power supply is good

    EVGA X99 FTWK / i7 6850K @ 4.5ghz / RTX 3080Ti FTW Ultra / 32GB Corsair LPX 3600mhz / Samsung 850Pro 256GB / Be Quiet BN516 Straight Power 12-1000w 80 Plus Platinum / Window 10 Pro

    thanks for the welcome:-)
    we are talking about

    MEM - This indicates if voltage to the video card's memory is good

    left to right when card is installed , connectors are towards me

    Does the gpu work ok when the leds are not lit? If so, it sounds like you may have some faulty leds.
