    Monitor goes off (black screen) Please help.....

    Hello guys, im new at this forum. I opened this account just for this unexpected problem and i can't find the solution. I request help from you all. Any reply is appreciated.

    Everything is okay with my PC, MY Rig is: i5 9600k 16gb ram gtx 1660 ti asus prime z370 P II motherboard.

    But i was trying to overclock a month ago (i was just trying the limits) and i boosted the clock like from 12000mhz to 15000mhz accidentally and i opened the fans to 80% speed. Then my monitor went off. I guess it was too much for it. Then i restarted my pc, everything was ok. Then monitor started randomly to black off and fans were at high speed (same as i made that overclock) . This happens when i play, when i watch something, even when nothing is opened in pc, just desktop.
    What i have tried : 1. I deleted the gpu tweak 2 application (where i overclocked my pc)
    2. i installed gpu tweak again and overclocked it like in so small amount like from 12000mhz to 12010mhz.
    3. i made a half format of my pc (just local disk C:)
    4. i made a full format of my pc.

    I tried all of these, nothing worked. And all i have in my mind is to detach the gpu at attach it again, nothing more. Please help me. I made a brand new PC with a monitor and this problem causes all by my fault and now i can't play any game that exists.

    Also check the additional power cables to the GPU are firmly connected.

    Check the CMOS battery voltage. My PC fails to boot if the voltage drops much below 2.8V. Try a new battery if your voltage is low and also load the BIOS defaults.

    A power glitch once corrupted my BIOS which was solved by reflashing the BIOS.
