Since yesterday the board is looping during POST. It starts and sthen shutdowns immidiatley. After a lot of attempts (50?) I am getting a "BIOS detected unsuccessful POST attempts, this may be due to changes in the performance options or recent hardware changes" messages. I can then either try to enter BIOS or continue. Yesterday I entered the bios, did nothing, exited and then it booted in windows. Today it isn't the case. I was able to enter BIOS once, I tried to reset default values just in case (had to configure RAID on SATA1 back though). After I exited, the POST starting looping again.
Of course I did no hardware change and no change to the performance options either! And I am pretty sure BIOS settings have always been the default ones before as well (except a RAID configuration).
So, what is the problem?? What should I do? If I have to RMA the board and get the same one, am I going to have a chance to reuse all RAID configured drives without a problem?
I never updated BIOS either, version is KLZ8711D-86A.0336.2013.0516.1957
Ok, I removed all hardware, that is all drives, pci card, pcie graphics (running from oboard graphics instead). Even the RAM. Without RAM the BIOS was beeping 3 times. Put it back in, same problem. Also removed and put back the CMOS battery (after a 24hours removal period).
The LEDs sequence is following: dd26 - dd44 - 0021 - 0003 - 0010 and then restart.
So I'm guessing either the board or the CPU is at fault?? How can I know which? The CPU is an i7 4770 (standard, non k version)
The whole system was purchased (separately) in august 2013, but not active before october (motherboard was not available right away)
I just noticed the CPU HOT led turns red before the system shuts down.. I guess I got my answer? What do you think? What would it mean though? Defective CPU? Bad cooling? It's a cooler-master fan.. and the system stayed hours online yesterday after I had the problem for the first time, without any issue...
The problem is exactly the same as described here:
However, my PSU is a Seasonic X-650, which is Haswell ready.
RAM sticks are 2 of the following, and theyre not low profile either: http://www.kingston.com/datasheets/KHX16C9P1K2_16.pdf http://www.kingston.com/datasheets/KHX16C9P1K2_16.pdf
I really need help, please!
