Asus Maximus VI Hero Issues

[sonicbloo4]

In the past 4-5 days I have been experiencing issues with my pc that started with a simple problem regarding the system time being thrown off at times, after searching the problem I thought it may have been a bad CMOS battery so I decided to replace that hoping to solve the issue. After replacing the battery the problem still seemed to occur as well as I started experiencing my ethernet dropping, every time it has gone down I checked my wireless devices connected to the same router to find that they were connected fine. The internet connection would remain off until I would unplug the ethernet cable and reconnect (from the pc port, unplugging from the router end didn't help) The ethernet seems to disconnect at certain times as well, today for example I have noticed it disconnect at 6pm exactly then 8pm (This could possibly just be a coincidence), It also disconnected at earlier times that I did not record the exact times of. Last I have been having issues regarding an reboot without warning, this only happens once a day. I am not extremely experienced with these kinds of things and I was hoping I could get some tips on either how to resolve this or what could be causing the issue.

Here's my specs if needed (I have had this build for about a year with no issues at all)
Asus Maximus VI Hero
Intel Core I7-4770k 3.50Ghz
Dual SLI EVGA GeForce GTX 760s
G.Skill Ripjaws X Series 16GB (8x2GB)
OS is Windows 7 64-bit

Thanks in advance to anyone willing to help!

Hi sonicbloo4 and Welcome to ROG.

As your system has been running fine for some time and these issues are suddenly occurring, I would initially suspect your PSU. (Please Specify)

Do you have a way of swapping the PSU or getting it tested.?

You may have to conduct a number of tests to determine the culprit, (if its not the PSU) as these issues may not be related, (a process of elimination).

You could try to reduce the load on the PSU by just running one GPU and one stick of RAM in the first slot, to see if there is any improvement.

Take readings using CPUz HWMonitor under load to get initial voltage readings with system as is,

Then take readings after removing a GPU and DIMMs (not definitive but an indication).

We have to start somewhere, so good luck and see how you go.

Thanks for the fast reply!
I don't currently have an easy way of testing my cpu, which is a Corsair HX850, but I will try to look for a psu tester tomorrow. In the meantime I will try disabling one of my cards and monitoring to see if there is any change. After a few reboots I also realised that when the computer turns on it will turn on for a second, turn off, then turn back on and start up normally, would that most likely be the psu causing the problem?

Follow this procedure to fix the frozen clock problem: Frozen Time Clock in UEFI - The Fix

While following the above method will also have you running the latest BIOS which might or might not fix the ethernet issues too. Report back your results.

That turning off and on is the Bios assessing and resetting system parameters and is initially normal, usually associated with changes made to frequency and voltage when overclocking.
It could be the PSU and you need to check this out first. Clear CMOS and set BIOS to defaults once you have established the PSU is not the culprit.

Have you made any changes to Bios recently?

Proper PSU testers can be expensive and its easier to take to an electrician with the proper equipment, who can test under load as the PSU can appear to be operational at idle but unable to maintain proper output under load.

Should the PSU be the culprit, make sure to get a gold or platinum certified unit, and I recommend a 1000w unit as minimal for your demands.
See how you go and please report back.
