Hi there.
I have a weird problem I can't seem to diagnose, so I'm asking for help, see if any of you have found out something like this.
The system is an i7 4940 with a Gigabyte H97-HD3 mobo, and 16 Gb of RAM (Kingston Hyper-X DDR3, 2 modules).
Upon booting, everything works just fine... but everytime power goes off (due to power failure, or whatnot), the system won't boot up till I clear CMOS, remove one of the RAM modules, and boot again... after that (I get to the UEFI screen saying to load optimized defaults or enter UEFI), I can just shut it down, plug the RAM module again and it'll again boot just fine.
At first I thought it could be some power issue... I don't have any spare PSU, but the one installed is a Tacens 800W relatively new (~ 1 or 1.5years), and unplugging everything from it (just keeping the mobo, RAM, Processor and using the integrated VGA) will not boot, so I'm ruling that out.
When I say it doesn't boot, I mean it bootloops... I heard a repeating clicking noise when booting, and I thought one of my hard-drives was going down, but after some diagnosing, the clicking noise actually comes from the PC speaker... it seems it gets to the point where the PC speaker is supposed to do the beep sound, but it reboots right after that (unplugging the speaker doesn't help either).
As I said, the system works just fine after booting (I'm writing from it), memory tests come out ok, and there's nothing "visibly" wrong.
I don't mind changing the mobo, the RAM, the PSU or anything else, but since I don't have spares and I don't want to be buying and returning parts, I thought I'd rather ask here just in case there's some specific things I could try first.
Thanks
