I have an Asrock Z87 pro4 board with an i5 4670 cpu , 2x4gb corsair DDR3 and a Geforce GTX 1060 3gb running Win10 64bit on a Kingston 120gb SSD with storage on 2 x WDC 500gb drives.
For the first year or so the system worked perfectly . For the last two years I have been unable to use 2 of the sata slots. Devices plugged into these slots do not work or even show up in the system. For the last 6 months or so the computer often gives the 3 beep signal at startup indicating bad ram . I have swapped in other ram from a known good computer. I have used one ram stick at a time in each of the different slots and still get the same 3 beeps randomly at startup. It goes on to load perfectly and run faultlessly after it does the beeps with no delay or restart.
In the last month I have had problems with the bios appearing to change itself. The boot disk changes to the storage WDC and will not start. If I go into bios and change it to the SSD with the OS on it , it will load properly. After a day or two it changes back again. It has now lost another sata slot so I'm down to 3 and I'm using all of them and have no spare for the DVD burner. At the same time as the latest sata slot stopped working I started getting the 3 beep signal repeated twice before it would start.
I have run the system with the PCIE card out and using the onboard video with exactly the same results.
I suspect the motherboard is dying but I cannot get a new socket 1150 board to replace the one I have and it is running beautifully apart from these issues.
I have tried to flash the bios but have not been able to get the Instant Flash program to work and the windows procedure tells me it can not work with my system. Is it possible to get a preprogrammed bios chip and install it myself .,They are advertised on Ebay, are they any good ?? Do you think bios could be the problem or is the board just dying ??
Many thanks Owen
I have also changed the onboard battery with no effect.
