2012 build wont post

Postby donmid94 » Mon Feb 29, 2016 6:24 pm

I have a computer that I built in 2012, this is the board: ASRock X79 Extreme9 LGA 2011 Intel X79 SATA 6Gb/s USB 3.0 ATX Intel Motherboard and CPU: Intel Core i7-3820 Sandy Bridge-E Quad-Core 3.6GHz (3.8GHz Turbo Boost) LGA 2011 130W BX80619i73820 Desktop Processor. Started out, wouldn't post or boot without retrying 2 or 3 times then 5 or 6 times and now no boot/post. I have pretty well ruled out trouble with the hard drive: OCZ RevoDrive 3 series PCI-E 240GB PCI-Express 2.0 x4 MLC Internal Solid State Drive (SSD) RVD3-FHPX4-240G, I stuck it in another machine and it actually booted to it. Took power supply and connected to other machine and ran fine. Disconnected all other hard drives and took out all but one stick memory: CORSAIR Vengeance 32GB (4 x 8GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model. I've never had a board fail,could it be the CPU? everything looks ok on the board, it has displays on board for reset cmos and power off seem to be working. Geez, just did a quick search and Mobo for socket 2011 chip not even available, so i guess I scrap CPU too? Ouch! this could leave a mark!
Any help will be greatly appreciated... Don M

One of the most common causes for a motherboard not posting is the 'bad caps' syndrome. Look over all the capacitors, if any show domed tops, excessive lean or leakage, they are bad. More info at www.badcaps.net/ .
Another common cause is the BIOS battery going dead. Typical life is about 3 to 4 years, depending on use. It is the redundant BIOS and CMOS power source when no mains power enters the PSU. It also provides power for the real-time clock, and if not functioning, maybe no life signs.
That LGA 2011 model is still available, if needed. New Egg, Amazon and eBay are sources.

So the board does function to a point. Are there any error messages or beeps? I would agree with Karlsweldt, check the board for leaking/bulged capacitors...

As far as the CMOS battery, like Karl mentioned there is a lifespan usually will be extended if the system has consistent power to it. But if the system or board has been sitting in the corner for a lengthy period of time you will likely encounter problems like checksum errrors, failure to retain date/time/settings..I personally have a tower suffering from this (battery failure). On mine it will detect drives, etc but does not have an OS so it won't fully boot. However if the CMOS battery is completely flat, I am not sure of the outcome.

CMOS battery is my bet.

That board has solid caps on it, it should not be part of the bad caps syndrome...

Remove all RAM and try to boot, if U get the usual beep errors then Ur system i going OK till the memory check routine, IF NO probably the voltage regulator circuit of the CPU is bad, look for the small caps located almost below the CPU heatsink

Ok got it down to just memory and 1 HD and 1 GPU and it boots maybe every other time. In my struggles, I must have hit to clear cmos so now by default, it goes to the Asrock "spash screen" and is looking for a keyboard command like hit delete for boot menu or f2 for something but it does not recognize keyboard. I switched to wired usb keyboard with ps2 adapter and that did not work either. Maybe I need true ps2 keyboard?

IF the BIOS pages are all reset to default, the USB "legacy" feature may not be enabled. Default would be the PS2 ports.
But whether connected to the PS2 port or USB port, same data signals are used. All AT keyboards use the same bit codes.
Check for presence of the +5 volts at the PS2 ports, and at the USB ports.
If no +5 volts present at the PS2 port, likely the fuse nearby has blown. Tiny surface-soldered component, usually tagged as "F1" or "F2" very close to the ports. The supply for USB ports is fused elsewhere. Use only a thin sewing pin to probe the PS2 socket, nothing larger!

The more stuff you remove, the better it boots -> power supply is suspect of bad caps.
