Update: my P8Z68-V PRO/GEN3 board stopped letting me get into bios, and came up lame with a VGA LED light always on. Breadboarded it (outside of case on non-static surface, no monitor, just power, cpu, one mem chip, reset CMOS several times etc etc etc), recycled through MEM OK attempts, switched mem sticks around and never got a single POST beep, and VGA LED stays on.
Dead board.
Called ASUS on Saturday.
Never, ever call ASUS on Sat if you can help it, they are incompetent and poorly trained. Took 10 minutes for the first guy to realize what I was talking about when I mentioned the board post LEDs: CPU, DIMM and VGA. He would just go silent on the other end for a minute or two. "Anybody there?" I'd ask. "Yes, I'm still here...so what board do you have?" This after the second go around. Good grief.
One tech was nice and actually apologized for the previous two guys I talked to, one of whom said he would get me a supervisor and kept me on hold for 15 minutes...though he knew there are no supervisors working on the weekends. Nice.
I may not be able to RMA the board either because it does not have a serial number sticker on it. The box does, the board does not. I took ten pictures and sent it to them by email, because they thought I was so lame I couldn't see a fracking sticker on a motherboard. I wish I knew how they train these folks.
Will arm wrestle with ASUS west coast supervisor tomorrow, danged if I'm going to eat a mobo that's been messing with my head for 5 weeks.
Bankster55 was very helpful, suggested I try a deluxe/gen 3 instead of the pro. It's on its way from Amazon along with a water cooler. If I have problems with it, I'm going to take a long walk off a short pier.
Sorry I don't have better news. Sure like the Pro/Gen3 board when it was running, between BSOD.
Bankster55 says Deluxe/Gen3 is solid, he builds systems as a pro so I'm giving that one a try. What they hay, not like I have anything else to do...
PS: could somebody snap a photo of a serial no. sticker on any ASUS board so I can make up my own from the barcode sticker on the box? That's one way I could get around their silly "policy", by making my own sticker from the one that's on the ASUS box, which has the barcode and everything, but since I've never seen the serial number on the board as it wasn't there when I got it from Newegg, I need to know how big to make it, what size the sticker is etc. Much obliged for anyone willing to do that. you don't have to even shoot it in focus, or can fuzz up the numbers or whatever, I just need to know the dimensions and the ratio of the characters to the sticker itself, and its size. Thanks!
EDIT: And where it should go on the board!
