Hello, having a bit of a weird issue lately. Occasionally when using the computer the monitor will go black and lose signal while the PC itself keeps on working perfectly fine in the background. I also sometimes have to boot the system multiple times to get any sort of signal in the first place, sometimes requiring that I go so far as to reseat the GPU before it will work properly. It can happen twice in an hour, or once a month. There also doesn't seem to be any correlation with the amount of load on the system. I can render video or play intensive games for hours on end with no issues only to have it crash a day or two later when browsing.
These are my specs:
ASUS P8Z68-V Pro
8GB DDR3 2133MHz
Corsair AX 850 PSU
OS installed on a Samsung 850 EVO 250GB.
My question is rather simple and I suspect I already know the answer, but what are the odds that this is due to the motherboard/PCI-E slot being somewhat borked? Basic stuff like resetting CMOS, changing DRAM slots, trying different monitor inputs etc yield zero results when this happen, but reseating the GPU seemingly works every time, which is why despite it being the newest piece of hardware and the most obvious point of failure, I lean towards the motherboard being the issue. I would try the GPU in the 2nd PCI-E slot or a different PC, but due to using a custom loop that would involve quite a bit of work, and as I am looking to upgrade to either Kaby Lake or Zen in the next months, I am honestly more interested in making sure there isn't some issue with the GPU, as I don't have warranty anymore after ripping off the cooler, before I go ahead with the upgrade.
