Ok so this PC was my first build so I'll apologise in advance for any noobie comments or mistakes.

Now I'm not sure if the issues are related so I'll just post it all here.

I've been gathering parts for this build since last September (2014) and finally managed to get it built over the summer, it worked fine for 3 months until in September I shut the PC down one night and it wouldn't turn on in the morning.

I'm talking no life at all really, the lights on the mobo would flash when I turned the PSU on but after that it stayed dark. I ended up replacing the PSU and the mobo and it worked fine. 3 weeks later it happened again.

I found out that other people with that mobo were having a similar issue and that there were some issues with that mobo and Corsair PSU's (which mine is) and there fore it changed the Gigabyte mobo for a MSI mobo.

Now I put it all together again and it worked fine. now 3 days after putting it together and while it will power on and that issue hasn't returned I'm having the following issue with my rig.

It started with me having to make sure the TV was turned on before the PC or i'd have to restart the pc as the TV wouldn't detect an input signal. now I'm having the issue that it wont detect a signal at all, the mobo has a debug code of 26 which i think is to do with 'early southbridge initialization' but not sure. I've tried my RAM and PSU in another PC and they're fine.

I'm really worried my Rig is a MOBO Killer. not really sure where to proceed from here. any advice?
See specs below.

CPU: intel I7 4790K
Cooler: Noctua NH-L9i LP
PSU: Corsair Hx1000i
RAM: 16GB Corsair Vengeance 2400Mhz (running at 1800 on Gigabyte Mobo and 1300 on MSI mobo - hadnt got round to setting up the RAM speed yet)
Original MOBO: Gigabyte z97x SOC
Current MOBO: MSI z97A Gaming 7
GPU: Sapphire R9 290
OS: Windows 7 ultimate
SSD: Kingston 120GB (OS)
HDD: 2x WD Green 4TB (Raid 1)
1x WD Green 6TB
Then a HDD from my old laptop for me to rip the data from think it's a 750GB (none permanent)
Disk drive: ASUS BC- 12D2HT Blu ray DVD combo
 
Solution
Ok so i've fixed this, it seems that with MSI dual BIOS boards if you update the BIOS (even if you use MSI's Software to do so) it causes faults if the 2 BIOS aren't the same version. resetting the BIOS to default via CMOS button fixed the issue.
