Hi All

I got great help here for a problem before 5 years now. I am back for more good advice and help.
Asrock H87 Pro4 Bios ver 1.90 most up to date on board when i got it.
Gskill F3-10600CL9D-16GBNT
Samsung 840 120gb ssd
Western digital 2tb
Gigabyte gtx 660 2GB
Shakroon 600W psw
windows 7 home P and updated some drivers.

Now since they took it home the memory is playing up.( i think thats the issue)

They machine after taking it home turn on but straight off not getting to bios just fan spin then off.

So i took out one memory chip and booted fine. Reseated memory chip again and booted fine.

If has been on and off not booting.

So motherboard is Asrock H87 Pro4 Bios version is 1.90 which is most up to date I didnt update to this.
Memory Gskill F3-10600CL9D-16GBNT (which is not on the memory compatibility list)

We had memory in slot 1 and slot 3 then for some reason only showing 8gb.
Moved memory to slot 2 and 4 16gb showing.

Then machine went back to not booting.

I have the person running memtest on one stick for 5 hours on 1 stick at a time to see if errors.

I checked the bios i remember for the timing at all looked fine on default detect but never saw the volts i dont think.

Any help and advice on this would be good.

Found this link on Gskill and H87 Pro 4 is on the list of motherboards

I finally got my hands on the machine.

So i cleared CMOS changed the pci-e to auto it was on Gen 1 as Gen 2 never worked before CMOS clear.

Reseated heat sink on processor.

Reseated Graphic card now all 16GB of ram showing too in windows and machine after a combination of restarts and shutdowns has no issues.

Thanks for the help

Raise the DRAM Voltage a little bit, set it to 1.550V or 1.60V and see if that is better.
