Helping my son troubleshoot his PC. He has a 2012 R4 purchased new. He says it is no longer under warranty. He had a lightning storm that knocked out power to his apartment while he was gaming. He had it on a power strip along with his phone plugged in to the same strip, After power was restored he could not get a video signal to the monitor. His phone no longer worked either. He swapped monitors but didn't work. We swapped cards, and swapped power suppplies with spares from my R3 I had. Nothing worked. We get a POST, but nothing to the monitor, and I mean nothing. No pre boot loading screen at all....just a black screen The fans on both cards come on.
Buy a real UPS like APC 1000-1500 and protect for next time.
