Hello everybody,
I've recently upgraded my system and now I'm facing a bootloop problem from time to time.
Usually it occurs when I meddle with voltages and/or clock frequencies. Sometimes the system crashes with a bsod, sometimes it doesn't. And after a restart, the system gets stuck in a bootloop. Means it powers up for half a second and powers down again and again and again and again.
So far so good. I know that can happen.
Strange thing #1:
Resetting the CMOS with the button on the back doesn't help at all.
Strange thing #2:
The bootloop occurs when I meddle either either with the CPU's or the dedicated GPU's frequencies (I don't use the Haswell's internal GPU).
Strange thing #3:
It solves itself after a while, i.e. only thing I have to do is leaving my computer turned off (power diconnected) for a while (about 20-30 minutes). Then I can turn it on again and it boots with a common double pump boot.
As long as I don't try any fancy overclocking the system works flawlessly.
During the bootloop nothing seems to help, only waiting.
What I've tried so far:
- tried booting with only 1 RAM module (tried both) - no effect.
- tried booting without any RAM - no effect.
- tried to reset the CMOS with the button on the back - no effect.
- tried to reset the PSU. I know that lots of people consider that humbug, but it can't harm to give it a try. Alas - no effect.
- tried booting without any devices/cables connected - no effect.
- tried to bridge the PSU. The power supply stayed on so I eliminate it as the error source.
Any suggestions on what the reason could be?
My system:
ASUS Maximus VI Formula
Intel i7 4470K @ 4000 MHz, 1,2 VCore
GSkil Trident X, 2x8GB @2400 (1200 MHz) @ CL 10-12-12-31, 1,53v
EVGA GTX 780 Ti SC, usually not overclocked any further.
Enermax Platimax 750w PSU
CPU, GPU, Mosfet and Chipset are watercooled.
I changed the original ASUS Crosschill for an all-copper EKWB.
Oh yes, maybe I should mention, that I've never noticed the bootloop previous to changing the Mosfet waterblock.
Thnaks in advance:)
