Asus z87-a continually restarting

[Devronicthetonicman]

Hey guys,

Motherboard: ASUS Z87-A
CPU: Intel i5-4670k
CPU Cooler: Corsair H-100i
Ram: Corsair vengeance pro 2x4gb 1866MHZ
GPU: MSI Geforce GTX 770 2gb OC/TF
PSU: Corsair RM850W

Last night I had a windows update that I decided to install while I slept. When I woke up in the morning I turn the monitor on to a page saying Overclock failed. I was using Asus's AI suite 3 for the auto-tune overclock as well as XMP for my RAM. For some reason when I Reboot my computer it keeps starting and then turning off, starting back on, and then turning off. It doesn't stop trying to restart. I pressed the MeMok! and it would restart fully but then my motherboards VGA led turned on and the screen wouldn't turn on because I lost power in my keyboard and mouse. I Then FINALLY press the bios button and it takes me to bios. I tried resetting everything to default but that didn't work. I boot up and the whole process started again with the continually restarting problem. So I get to BIOS AGAIN and I have to force start windows through my HDD. Games still play great, got internet, screen, keyboard and mouse all work.

So why in the hell is this happening every time I reboot my computer? I really don't want to put up with this anymore...help!

Chances are the automatic overclock applied is not 100% stable which is why the board struggles to POST. This can happen with some CPUs that require more voltage that the auto-tuning rules apply for a given frequency. You can either clear CMOS and set the overclock yourself (manually). Or you can try reducing the CPU ratio by one step and see if that helps.

Is it possible I just have a bad CMOS battery? and By ratio do you mean the CPU cache ratio? sorry complete OCing noob right here.

 

[raja@asus]

No, it's not the battery. I mean CPU multiplier ratio (for core frequency not cache).

Check that you have the latest BIOS, and might want to reseat the DRAM and then enable XMP and select profile 1

I'm sorry guys I'm sort of a noob at this. So by adjusting the CPU multiplier ratio I would select group tuning and then bring the ratio down from 3800MHz to 3700MHz? Also I checked for the BIOS and I'm good. How do I reseat the DRAM? Is that just setting it back to the default speed before XMP?

Also i've noticed when it's doing the restart thing if I unplugged my PSU for 5 seconds and then plug it back in I'll be able to boot into BIOS and force boot from my hard drive into windows. Just thought I point that out.

Reseat is to pull the DRAM and reinstall it firmly...the bit w/ the PSU might be it's weak or headed south, see if you can try with another PSU, (borrow one if none available)

I don't have an available PSU, however I don't think that's the problem. I reseated my RAM and my GPU. still having the problem. If I turn the system off and then press the power button it will boot up and then the VGA led will be bright red and I won't have any monitor display. If I reset my computer it will turn into a continuous cycle of restarting....

Clear CMOS and keep the system at stock for a few days - just to make sure it is stable there. Can think about overclocking later..

yep that's all I had to do. Thanks buddy.
