Maximus V Extreme rebooting

[Canuckz]

Help! After recently downloading a game and leaving the computer unattended when I came back my computer now wants to constantly reboot. I have tried the following:

1. swapped out the memory with new RAM - still reboots
2. pulled out the battery to reset the CMOS - still reboots
3. disconnected all the hardrives, soundcard, etc. - still reboots

I try to get in the BIOS to see if I can change anything but I am only in there for 5 seconds before it reboots. I notice it gets to A3 on the LED indicator before it happens. Any other suggestions before I have to rip my computer apart to try to RMA the board? Thanks for any help.

The board had all latest updates installed around a month ago when I installed it.

i7 3770k

Welcome to the Republic of Gamers forums, Canuckz.

Please list your complete system specs as detailed as possible for us so that we can help you better. 😉

updated with specs, thanks.

When you switched on your system, please verify that your H100i is working. Start by inspecting the pump for me. And are the Noctua fans on the radiator spinning?

[Canuckz]

The fans are spinning. How can I check if the pump is running? When I get in the BIOS I hurry up to go to the Monitor tab to see if Temps are high but they are at 28 C before the reboot happens

[Chino]

There are a few non-technical methods to see if the pump is indeed working.

1. If you touch the CPU block, you should feel the movement of the liquid as it is going in and out of it. Generally the CPU block should be a little hot. Also if you put your ear close to it, you can hear the sound of the liquid in movement.

2. If you start feeling the tubes, you should notice the movement of the liquid racing from the CPU block to the radiator and vice versa.

It sounds to me like you have a pump failure. Easy way to test is to swap out the water block and use your stock intel fan. If your board works normally then you know it is the cooler.

Assume you have done the basics like a full clear CMOS??

I felt the pump and hoses and there seems to be some vibration but I can't tell 100% if its coming from there or just the case in general from all the fans. I have to try to find a stock cooler as I threw it away. So to clarify, if the pump fails it will just cause it to constantly reboot?

Update:

So I just now brought the computer to work with me to see if I can resolve this. I left my video cards, WD drives and soundcard at home but plugged back in the SSD's. I get to work and realize im an idiot and I need a video card so I grabbed a new one here and plugged it in. Booted up the computer expecting it to reboot but now it is working fine.

I am really scratching my head here on what would cause the computer to constantly reboot at home but now it is fine. Thoughts?

If the pump doesn't work, then there would be no movement with the liquid to dissipate the heat from the CPU which in return will cause it to get really hot to a point where it would just reboot or shutdown depending on how hot it gets.

Did you take the whole case with the motherboard inside to your work? Or did you take out the motherboard, CPU, and RAM out of it? Also which GPU are you using to test it with?
