I have had this rig for the last year. This morning it was powered up but would not wake up. Rebooted to get a 0_ in lower right corner. Rebooted after pulled power five + times, sometimes POST code 00 or 69. Cannot get into Bios at this point. I pulled the battery and am letting it sit for an hour. i will relocate the usb mouse and keyboard and will retry. I have another system so i can pull parts and troubleshoot.
System has worked flawless for the last year.
msi gtx760 4gb
16 gb kingston xtream 2400mhz
samsung pro ssd
900 watt antec pro gamer power
Here is the update.
I put battery back in, it gave me a prompt for CMOS detecting no battery. Replaced with new battery and computer booted up.
Intel has a strange way of telling people that they battery is dead. Strangest part is that none of my BIOS configs are set to default. Not sure why I pulled the battery to clear anything. Anyhow, I am thankful I only lost 3 hours of work today.
