After "upgrading" my machine (I've replaced so much, it's hard to call it an "upgrade" any more), the computer will frequently reboot, almost always within a minute of loading the operating system. The reboots take the form of the computer completely and immediately powering off, followed by a few seconds' delay, before turning back on.
I should clafiry: if I boot it up, log into the OS, and then just let it sit, the computer stays on and doesn't power off. It's only after I start doing stuff (sometimes as little as surfing the web, sometimes as much as loading a virtual machine, running USB capture software, and recording using screen capture) that it powers off.
The CPU isn't overheating--temperature rarely exceeds 40C and has only once gone above 60C--and I just replaced the PSU to no avail. In my experience CPU and RAM issues lead to kernel panics, and OS issues lead to less abrupt (and more descriptive) shutdowns than this.
So that leaves... what? The motherboard? Is there anything else I'm overlooking?
Relevant Specs:
-Intel i7-4790k
-Gigabyte Z97X-UD5H motherboard
-Seasonic G-Series 650W PSU
-OS: Ubuntu 14.04
The only other thing I could possibly think is that 650W is not enough power, but that seems insane, so here's everything else being powered by the PSU
-Corsair H60 liquid cooler (thru mobo)
-nVidia GT 430 video card (using it for D3D, not currently powering any monitors) (thru mobo)
-DVD combo burner, 1 SSD, 3 SATA HDDs, 1 PCI TV Tuner, several USB 2.0 devices
-Cooler Master HAF 932 case (read: 4x case fans)
My next steps will be to flash the BIOS (I think I'm on F6 right now and there's an F8 version), then check for bulging capacitors on the mobo. So I guess I'm wondering what to check if/when that doesn't work.
