Just built a friend a new system. Specs are ASRock Z87 Extreme4, 4770k, 2x8GB GSkill 2400, Samsung EVO 500GB, SeaSonic 650W, and GTX660.
Edit: OS is Windows 7 x64 SP1 updated
It was up and running just fine for about two weeks (with a mild overclock to 4.2 @1.195vcore, most everything else full auto). Today he called me and said he was working on it, and it just suddenly turned off - in his words it 'wouldn't wake up from hibernation'.
It's very strange. The system appears to turn on fine, but will not output anything to the display no matter what. Here's what I've tried:
-(Before I gave him the PC I ran memtest86+ for 24+ hours with 0 faults).
Since getting the PC back from him today I've....
-Cleared the CMOS. I actually have done this multiple times at different points by various methods - by both the jumper and the ASROCK quick cmos clear button. At the very end I even went so far as to make sure PSU was disconnected, drained residual power, and pulled the mobo battery.
-Disconnected all drives.
-Pulled out the PCI-E graphics and tried the built in IGP, then reseated PCI and tried it again. And I also tried all outputs on multiple displays.
-Unseated/reseated RAM, and attempted with only 1 DIMM (each DIMM the system came with, and 2 other known good Corsair DIMMS were all given chances by themselves).
-Changed out the main power cord, and also unseated/reseated all motherboard power connectors.
Throughout all of this the ASRock DrDebug thing has given me various fault codes including: 6A, 61, 63, 68, 69, 71, 72 (Maybe some others but I'm pretty sure they all started with a 6 or 7). Per ASRock's DrDebug chart here: http://www.asrock.com/support/faq.asp?id=334
it seems all of these codes stand for "Chipset initialization error. Please press reset or clear CMOS."
I was going to contact ASRock support, but it appears they're out of the office for chinese Holiday, and I'd like to get the part RMA'ed for him first thing Monday if I can be relatively certain what the culprit it.
So anyone else have a trouble shooting suggestions, or is this just a bad motherboard that I can RMA asap?
