PC Powers OFF during 3dMark : HELP Please!

[zoopnfunk]

I have just completed my first solo pc build. Now I am in the testing phase and having a big problem. I started with the Prime95 blend test and the pc performs well. It maintains temperature and does not crash. Now I am running 3dMark and during certain tests the pc just powers off and reboots. The event viewer only contains a log for an unexpected shutdown.

Ice storm - all tests run to completion with FPS in the thousands.

Cloud gate - pc powers off immediately on the first test.

Fire strike - first test runs with over 100fps. Pc powers off and reboots near the start of the second test.

Here are the components in my PC, running Windows 8.1:

Intel Core i7-4770K 3.5GHz Quad-Core
CPU Cooler Corsair H110 94.0 CFM Liquid
Thermal Compound Arctic Cooling MX4 4g
Motherboard ASRock Z87 OC Formula/ac EATX LGA1150
Memory Corsair Dominator Platinum 32GB (4 x 8GB) DDR3-2133
Storage Samsung 840 Pro Series 256GB 2.5" SSD
Western Digital Caviar Blue 1TB 3.5" 7200RPM
Video Card EVGA GeForce GTX 780 Ti 3GB
EVGA GeForce GTX 780 Ti 3GB
Case Rosewill BLACKHAWK-ULTRA ATX Full Tower
Power Supply SeaSonic 1000W ATX12V / EPS12V
Optical Drive Pioneer BDR-2209 Blu-Ray/DVD/CD Writer
Operating System Microsoft Windows 8.1 Pro - 64-bit (OEM) (64-bit)
Custom NZXT Fan Controller

Just prior to the power going I notice some sort of wheezing or clicking sound I believe to be from the GPU. I observed the same behavior with SLI enabled and disabled.

Please help me out here fellows.. I am totally lost and unsure what to do next. This pc represents a considerable investment and I really want to figure this out from both a personal pride standpoint as well as a monetary one.

Thoughts? I've read elsewhere that the pc powering off must be psu related. I am running a seagate 1000w platinum. Is that enough for my build? I thought I was giving myself some breathing room by choosing a 1000w but maybe no?

Thanks everyone... I really appreciate and advice and help I can get on this one. I'll run and suggested tests, I just want to know what is going on here. This pc should be a beast: not die on a cross platform stress test 🙁.


Thanks !

do you have your cpu overclocked? also check your cpu volages they shouldnt be above 1.25-1.3

do you have your cpu overclocked?

I have not OC'd the CPU as of yet. I do want to check how the water cooler is hitting the CPU. I don't have the highest confidence in my installation. I used the stock thermal paste applied to the corsair heatsink -- I was nervous about removing and applying my own.

It seems curious that the CPU would overheat or become taxed in only a few seconds of running 3dMark, but not overheat and shutdown running at 100% on Prime95 blend test, doesn't it? I'll also noted the max temp I recorded on the CPU while running that test was around 58C. I was getting hotter with Prime95 and the MB controlled fans weren't maxing out to keep pace yet.

I want to use my MX-4 thermal compound anyway so re-seating the CPU and applying that paste seems worthwhile even if it doesn't solve the issue. We'll see, fingers crossed!

Bad news: Crashed loading Bf4 during the cut scene just before going to the menu.

I double checked the protection setting in the BIOS while re-enabling it and it is specific to the Motherboard overheating. Seems like it could be a MB or PSU issue I guess.

im hopin for you, other than that your temps seem fine. check your voltage on your cpu though make sure it is 1.25-1.3. it is strange about p95 not crashing, it could be a faulty sensor on your mb too.

I went to the BIOS and did some more tinkering. In addition to loading the profile that comes with my RAM I changed the CPU to an overclock present with a higher voltage. I re-enabled the overheating protection for the MB and left all other settings to default.

So far so good... I was able to play Bf4 for three hours this morning. I was afraid to run 3dMark. After finishing Battlefield I loaded 3dMark fully expecting it to crash. Much to my surprise it ran through all of the tests to completion. I ran the 3dMark11 demo that crashed on me as well and it completed also.

Is there ever a scenario where overclocking the CPU could actually stabilize a PC? Does matching the voltage on the RAM matter? Stupid questions, I know...

Thanks folks!
