Hi, Yesterday I've switched my current CPU(G4560) with (6700K) also added 8GB more ram(before 8GB) and the monitor was showing me black screen. Motherboard(ASUS B250M-K) was working, all fans were spinning. So I thought maybe motherboard is incompatible with the new CPU. Then I downloaded the CPU compatible BIOS update from the Asus website and I noticed there was no BIOS reset button. So I've took out the battery from the motherboard waited ~5ish minutes and put back in started the PC still nothing. Just black screen even everything seemed working fine. So I thought I'll just put back the old CPU(G4560) and then I'll update BIOS. So put back the old CPU started again. Same black screen. Then I thought maybe the new RAM's fault and unplugged that started again. Same...

Here's the list what I've done after that:

• Changed the RAM slot

• Changed the RAM

• Changed the RAM slot again

• Unplugged all the drives

• Rechecked the CPU thermal fluid, reapplied again

• Unplugged the GPU and changed to onboard display

• Rechecked all the cables, monitor

• Started PC without RAM but no beep error sound

All the result's were same PC starting fine, but no display.

Here is my setup:

• ASUS B250M-K

• G4560 (new 6700k, I've also got 7700k)

• 8GB DDR4 2400Mhz (+8GB)

• Corsair CX 500 W 80+

What should I try next? Is my motherboard dead? Should I just give up and call support?

Thanks
