Hi:

My PC takes about 15 minutes to post to bios when cold started. Once booted into windows 10 it seems to run fine. Its also fine when soft rebooted. I have tried removing all connected devices except the monitor, keyboard and mouse--has not helped. I have tested my ram and did a chkdsk, both report that respective components are fine. I did notice that the memok led on the motherboard goes solid red during a cold boot. My setup is as follows

Windows 10--64 Home

Asus z68-v-lx
intel Core i7 2600k
8gb Kingston hyperx
ocz vertex 3 128 GB SSD
WD15EARS HDD
WD3200ks HDD
ASUS Radeon R9 290
OCZ Modx stream pro 700w power supply

Thanks for your help.

Your RAM has right speed if it shows 800mhz, more info for the memory https://en.wikipedia.org/wiki/DDR3_SDRAM

You may try update the intel chipset driver win10 version, http://www.guru3d.com/files-details/intel-chipset-software-installation-10-1-2-8-whql-download.html
May test the ram by MemTest86 http://www.memtest86.com/download.htm

Next thing to try use the intel XMP profile (Extreme Memory Profile), check the manual for how to. If the RAM are the Kit, use one then set the XMP, shut down the pc, and add other one, then reboot the pc again.

Do you have the program(s) that you installed it ( them) into either WD15EARS or WD3200ks? If yes, try disable it to start by msconfig feature or delay its service in the computer management. I think the pc searches the program in other drive if you install it into other HDD instead of the SSD, those program like the antivirus, photoshop, etc.
Also you may check the S.M.A.R.T. by CrystalDiskInfo http://crystalmark.info/software/CrystalDiskInfo/index-e.html for all the hard drives. And you may try update all the drivers for MB, devices because you use the win10, and we know it has the driver compatibility problem.

Hi. Thanks for your suggestions. I have narrowed it down to the RAM. It would seem that the two slots furthest from the cpu (A2 B2) are the issue. The 2 modules themselves seem to be ok, as I have used them individually and now I have them together in the two slots closest to the cpu (A1 B1). The system now boots normally, but instead of running at 1600mhz they are shown as running at 800mhz. Not ideal, but I can live with it for now, unless the MBis dying. Any diagnosis\solutions for the problematic memory slots would be helpful.
