I just built a new gaming rig (first time building my own PC) and used the Sabertooth z77 as my Motherboard. Here is my build on PC-Part-Picker:http://pcpartpicker.com/p/iS9c
Intel Core i7-3770K 3.5GHz Quad-Core Processor
Corsair H100 92.0 CFM Liquid CPU Cooler
Asus SABERTOOTH Z77 ATX LGA1155 Motherboard
G.Skill Ripjaws X Series 16GB (2 x 8GB) DDR3-1866 Memory
Corsair Force Series GS 360GB 2.5" Solid State Disk
EVGA GeForce GTX 580 1.5GB Video Card
Thermaltake VN300M1W2N ATX Full Tower Case
Cooler Master Silent Pro M 850W 80 PLUS Bronze Certified ATX12V / EPS12V Power Supply
I'm having some issues with it though, my PC randomly will restart. No error messages will come up or BSOD, just as if you flipped the power switch on and off again or hit a "reset" button. Usually when this happens it will restart AGAIN during the booting process. So, either during the BIOS loading screen or the Windows loading screen it will restart itself again. Sometimes it even gets caught in a reboot "loop" doing this over and over again. Sometimes it will bring me to the screen saying Windows was unable to start, and asked if I want to launch startup repair.
It's odd though because I am able to play Guilwars 2 for hours on end, and not have a reboot occur. But it seems if I am doing anything else it will reboot itself within a half hour or so. I've had it reboot during games, browsing the net, etc. I tried just booting it up into windows and letting it sit there idle, reboots after a certain time for that. Then I tried just booting into the BIOS, and it will randomly reboot just sitting in the BIOS too.
I don't think it's due to any overheating either, been monitoring CPU/GPU temps and they have been staying pretty low, GPU got up to the 70C range during some Nvidia stress tests I've been doing, and the CPUs have stayed in the 30's and low 40s. Plus the reboots happen when the system is just idle or just in BIOS, so probably not load/stress induced.
I'm using the newest BIOS version (1504) which was what came on my MoBo, all I did was load the drivers and whatnot from the MoBo disk that came with it, then downloaded drivers from my nVidia disk and went to the Nvidia website and got the latest driver.
Here are two pictures I have taken. One of my BIOS home screen. The other is of my components in my case. One thing I have a question about... there is a red LED that's lit up right by my USB 3.0 input that you can see in the one image... is this supposed tobe red? Or green? Not sure if it being red means there is a problem with something.
Anyways, some input or advice as to what might be causing these reboots would be much appreciated.
