Hi,

So I've been having LiveKernelEvent 141 black screen crashes during gaming during these past few months or so. I would be gaming and within 10-20 minutes in, suddenly my monitors go black, and I can hear something disconnecting, which I suspect is probably the GPU. I've had this custom built PC for about 5 years now and this issue has only started happening within the last year or so. What I need some help diagnosing is whether this is a GPU or PSU related issue. What's strange is if I run MSI Afterburner and reduce the power limit to < 90%, I don't get the crashes as often... which makes it appear as if the GPU isn't getting enough power but 620W should be more then plenty - is the PSU just getting old? What does the community think?

Current specs below:
  • GPU = EVGA GeForce GTX 980 FTW ACX 2.0
  • CPU = Intel Core i7-4790K 4.0GHz LGA 1150
  • Motherboard = MSI Z97S SLI Krait Edition LGA 1150
  • PSU = Antec HCG M Series HCG-620M 620W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS BRONZE
Thanks
