Did you cook something on your PC?
I was attempting to increase the clock speed and was following some overclocking guides. I expected a stable performance at around 4.9 ghz on an i7 7700k with auto voltage. My machine started up and ran for several hours initially, but as time went on it began to black screen and would restart from BIOS. Eventually I lowered the frequency to 4.8 to achieve stability. However, the crashes persisted, so I returned everything to the default BIOS settings. It continued to crash during boot. Unbeknownst to me, I had set the overclock too high from the start and shouldn't have pushed it that far. Now my system shows lights on the motherboard, fans are spinning, and the GPU is also active, but all peripherals fail to connect and the monitor displays nothing. A friend suggested something might have been damaged internally and mentioned a possible GPU failure. I previously resolved an overclocking problem by removing the battery from the motherboard and resetting the BIOS, but I doubt this will fix this current issue. I plan to try again tomorrow, though I didn’t sleep well last night.
I attempted it once but I can try again when I get home. I believe there might be a more significant issue.
Did you verify the temperatures and voltages during this build? It's possible you might have damaged the CPU. Are there any BIOS beeps or error codes when you power it up? You could also try disconnecting the graphics card and using the built-in display to check if that helps.
