    Upgraded GTX660 to GTX1070, now Lenovo K430 won't boot

    Hello All,
    I've been trying to upgrade my Lenovo K430 from a EVGA Nvidia GTX 660 (not stock) to a EVGA Nvidia GTX 1070. The system operates fine, I just want to upgrade my performance.
    Current specs:
    Win 7 64 bit Pro
    24 GBs RAM
    Intel i7 3770
    CIZ75M Motherboard (stock lenovo)
    Thermaltake Smart 650w PSU

    When I put in the new gpu, the screen shows the Lenovo title screen and the gpu fans spin for a second, and then it stops. The system then has 3 spaced out beeps and the screen goes black. The Hard drive will spin up for a split second the the bootup never begins.

    PS. I have narrowed it down to a BIOS/MOBO issue. Lenovo hasn't supported this platform since 2012 and is unflashable (Lenovo Says). Would upgrading to WIN8.1/WIN10 fix this problem is the GPU too new for my out-of-date (4yrs old) system. Please Help..........

    try and disable secure boot.

    Assuming that you've checked the obvious like power to the gpu etc ??? However if your bios is un-upgradable you may be sh!t out of luck. I had this issue with my R9 290 and old motherboard that hadn't been updated to a UEFI bios. Luckily for me there was a newer bios that fixed the issue, once the newer bios was flashed the motherboard would boot with the new card.

    Re: Upgraded GTX660 to GTX1070, now Lenovo K430 won't boot

    When i googled 3 beeps i got a few different results, but depending on how easy it is i would try the 1070 in a different pc to make sure its not faulty. But ive run newish cards like the 960 on hardware as old as that with no issues before. If you have a spare hdd try doing an install of windows 10 on to it just to try.
