HI.

Overclocked my i5 6600k to 4.5GHz. Run all the tests after, looks stable.

Problem is when I'm turn my computer on.

Black screen with cursor blinking, always, just that, black screen with cursor blinking.

I then need to RESET my computer and then loads up Windows no problem?!

Check CPU-Z and 4.5GHz is running, weird.

Any idea whats going on?

Like I said, cold start, black screen with blinking cursor, then reset and works fine... every, signle time...

Is it overclock fault?
 
Solution
when you reset the bios/uefi the system will detect all the hardware. so its possible.
but it does sound like something is going wrong in the bios/eufi for it to loose the drives.
like i said mate. "NORMALLY" the flashing cursor means it cant find a boot device. but its not the only reason a bad oc/ cant find other hardware could be stopping the eufi/bios detecting the hardware properly. and resetting solves it.

try turning the ram down to default see if that helps.
if not turn the oc off completely.
basically its a process of elimination.


What average temps are you reaching on it and whats your voltage? Typically I would let the overclock stress test run for 12 hours+ to guarantee that the overclock is stable. I personally use prime 95 but other programs work fine too.
 
Used Prime95, all good, temps very good.

TUrning my comp off, then back off, black screen with cursor, until I reset and goes perfect... weird

Voltage, stock, temps max 82 when on prime95
