Since a couple of weeks my PC sometimes gives 6 short beeps before giving 1 bios beep and continuing to boot. 6 Beeps meaning "The keyboard controller IC has failed, which is not allowing Gate A20 to switch the processor to protected mode. Replace the keyboard controller" I ignored the problem as my pc was booting. Last weekend I got 3 sequences of 6 beeps without posting. On resetting the pc I managed to get it booting again. I decided to investigate the problem a bit closer and now I got continuous sequences of 6 short beeps without booting. I removed all usb devices and I get 2 short beeps: Memory parity error A memory parity error has occurred in the first 64K of RAM. The RAM IC is probably bad I tried following steps to get more info: - removed all the RAM modules: continuous beeps indicating no memory - tried various combinations of RAM and RAM banks: 2 bios beeps as I don't have spare memory modules I have not been able to swap memory and test again. - removed graphics card: beeps that no graphics card is present - reinstalled everything: 2 beeps but no post The rest of the hardware is: - Asrock Z97 pro 4 - Kingston 16GB (2x 8GB) 1600MHz DDR3 HyperX Fury White - Intel Core i5-4690K - Corsair 520W power supply - ASUS nVidia GeForce GTX 750 Ti 2GB GDDR5 graphics card Is the motherboard or RAM at fault? All input is appreciated |

Is this a new build, or one that ran ok previous to this? -- Also, I'm guessing a gaming keyboard and or mouse. 1. Is the gaming KB/M using the latest FW and drivers? 2. Is the boards BIOS flashed to the latest NON-BETA BIOS release? 3. Do you have a plain jane USB or PS/2 KB/M to try with. A BIOS reset prior to swapping would be in order here in this instance should you. 4. What specific model number Corsair 520w, and how old is it? The 750Ti can draw150W plus some. |

Hi, - This build has been running fine since May 2015 - The keyboard is some cheap/standard logitech keyboard - The mouse is a logitech Performance MX (1ste generation) - All latest firmware and drivers were installed (as my pc doesn't boot I can't tell what the exact versions are) - The motherboard has been updated with the latest bios (again I can't recall or check the latest version) - I cleared the CMOS in my debugging session - I would love to get into the CMOS, but I don't get that far... - The PSU is a Corsair HX520 Modular power supply. It's 8 years old, from my previous build. |

A motherboards ancillary "devices' will usually be the first to act up in a low power situation. Seeings your eight year old psu is now long in the tooth, do you or a friend have a newer or larger wattage psu to test with? |

And again, seeings you will be changing out a major device(PSU) due to possible problems relating to it, a BIOS clearing, not a simple reset, would be in order. EDITED FOR CLARITY |

I've used this PSU calculator; http://outervision.com/power-supply-calculator It seems I would need a 367 Watt psu. My 520Watt PSU should suffice, but of course it's 8 years old. I don't have spare parts (memory, psu,... around... so it's really difficult to debug, I know...) I have cleared the cmos by shortening the 2 pins on the mobo, as well by removing the mobo battery.... |

What I'm getting at by hinting about your current eight year old PSU is ........ Is it Dual railled? Does the PCIe graphics power have its own rail, or shared on one rail? etc etc As I'm sure you're well aware, eight years ago things were very very different in terms of what and where a PSU's power output was designed. I'd still like to know what model number of PSU you have, but I'm of the opinion you first need/should upgrade your current one, regardless. Not that it will necessarily solve this problem you have, yet it surely is not helping either. Consider. The PSU is the foundation upon which everything else is built atop. Anything built on a weak foundation is bound to give you problems sooner or later. |

And BTW, that's the PSU Calculator I rely upon too. |

I will look up the exact model number when I get home. But from memory, I think it's this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139001 |

Knowing 8yr old PSU's loose some over time .......... That'd be ~216W on each rail, with your video card eating up 150w plus. When new. Good news it is a Seasonic manufactured unit. http://www.realhardtechx.com/index_archivos/Page447.htm JohnnyGURU review of that particular PSU you linked. Reviewed on Tue, Aug-15-2006 http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=18 No friend that would "lend' you one for a short time? hehehe I'm near Kalamazoo if you are near and need one to test with. All Seasonic too. |

Modular huh? If yours is modular you might check by scrubbing the modular contacts for a good/better connection, considering its age. Without fully pulling the plastic cable end out of the PSUs connector, move them slowly in and out six or seven times, slowly so as you don't deform the soft/delicate brass terminals within the plastic plugs themselves. Oxidation on old connectors/connections(Modular PSUs) is not a good conductor of electricity. One searchable word: Caig |

Hmm, I'm reading more info on the graphics card: this should be one of the more frugal cards at only 60 watts... The GPU is ASUS nVidia GeForce GTX 750 Ti 2GB GDDR5 |

Ok, I did some more research on my pc / psu today: All voltages my psu is delivering are just perfect, BUT I heard a ticking/click noise from the psu. It sounded like a worn bearing in the fan, but it's not the fan. Probably a capacitor which is dying. Seems like you were right after all, it's the PSU. Going to order a replacement today. Kind regards, - |

Ok, I replaced the power supply today with a brand new Corsair CS550M to no avail. I get 2 bios beeps and then 6 beeps. I think it's 6 beeps, but could also be 2 times 3 short beeps. I found it very difficult to tell... I posted a little video here: https://youtu.be/B9Fsrt_fSs0 |

Did you try removing the video card and use the CPU graphics for a test? Clear the BIOS before starting the PC after removing the video card. Memory should be put in slots A2 and B2, the black slots. You should also try using one DIMM only in the B2 slot. ALWAYS clear the BIOS after making changes like this. Since the PC was working/booting at one time (right?), then something either broke or possibly a Windows update may be causing an issue. What OS are you using? You mentioned earlier beeps occurring after removing the video card, which is weird since you have onboard graphics, but perhaps you did not have a cable connected to the IO panel video outputs? You could disconnect your OS drive and you could still get into the BIOS. The progression of your problem indicates something became worse as time passed until you could no longer boot. IMO it's time to strip the PC down to bare essentials and test it at each phase of adding ONE piece of hardware. I would disconnect ALL of your drives first as well as the video card, connect the monitor to the onboard graphics, clear the BIOS before starting the PC in this state and see what happens. Trying different memory would be great, if you could. ------------- http://valid.x86.fr/48rujh" rel="nofollow">

Hi parsec - I tried removing the videocard, but this time I have connected my monitor to the onboard graphics. I hadn't tried that before. The result is the same: 6 beeps in a loop. - I tried booting with only 1 RAM dimm installed in slot A1, A2, B1, B2 - I have disconnected all other hardware like esata card reader, dvd drives, all hard drives including the OS drive - This pc runs Windows 10 - I really can't tell when the problems started. All of a sudden I got 6 beeps, 1 bios beep and the pc booted normally. The problems got worse and worse and now I'm in a situation where I can't get in the bios anymore. A RMA for the motherboard has been requested. In the mean time I have replaced the power supply as this was starting to fail (clicking sound). |

So finally, (almost) one month later and I got a replacement motherboard. Everything is finally working again as it should. Meanwhile I had some interesting times on an old Linux machine :) Thanks everybody for the input. |

Hi. I have the same problem with my Z97 Pro4. Everything has been reseated and reconnected. It is running on only one ram module. It takes forever. But if I wait long enough it will eventually boot into Windows. It has just gotten a fresh installation of Windows 7 on a new hard drive. The hardware is: - http://rover.ebay.com/rover/1/711-53200-19255-0/1?type=2&campid=CAMPAIGNID&toolid=11000&customid=CUSTOMID&ext=381258609951&item=381258609951&ipn=psmain&icep_vectorid=229466&icep_ff3=2&icep_item=381258609951" rel="nofollow - Asrock Z97 pro 4 - Kingston 8GB (1x 8GB) 1333MHz DDR3 - Intel Xeon E3-1230 v3 - http://rover.ebay.com/rover/1/711-53200-19255-0/1?toolid=10029&campid=CAMPAIGNID&customid=CUSTOMID&catId=58058&type=2&ext=191804504389&item=191804504389" rel="nofollow - 700W power supply - http://www.ebay.com/sch/i.html?_nkw=nvidia" rel="nofollow - nVidia http://www.amazon.com/ZOTAC-NVIDIA-GeForce-PCI-Express-ZT-70601-10M/dp/B00IFZ547Q" rel="nofollow - GeForce GTX 660 2GB GDDR5 graphics card I am more than certain that it is a motherboard issue. If any solution has been found. Please let me know. Current BIOS version is 1.3. And I plan to update it soon. |
