Got my new kit from OCUK today:
Krypton G1 Killer Intel Core i7 960 3.20GHz @ 4.00GHz DDR3 Overclocked Bundle
Asus GeForce GTX 580 DirectCU II 1536MB GDDR5 PCI-Express Graphics Card OCZ Vertex 3 MAX IOPS 120GB 2.5" SATA-3 Solid State Hard Drive (VTX3MI-25SAT3-120G )

Removed the old mobo, mounted everything and launched. Nothing on screen. Plugged in my old HDDs as well, rebooted, a new message came up on screen saying the overclocking had failed and it had gone back to defaults. Woohoo everything worked so I installed windows etc.

Noticed the i7 was running at 3.2 Ghz so went back into Bios and chose the optimal settings preset. Rebooted.

Nothing on the screen. Not even Bios. I rebooted several times- still nothing... It makes it into windows though because I can hear the windows startup sound. Everything works except the display.

Removed the graphics card, stuck my old 240GS in a different slot. Same thing- no bios, nothing.

Pressed del to go into bios at next boot. F6 to load defaults, pressed y then enter then f10 then enter. Still nothing.

Took power cable out and joined the CMOS plugs with a screwdriver. Waited, rebooted... nothing!

I'm at my wits end here- any help would be very much appreciated!

thanks!
 
Yeah no post, absolutely zilch output on screen. Monitor is fine, cables are fine.

I'll try the battery/cmos trick and see if that works. First to find a jumper though... thanks for the suggestion- will post a reply if it works!
 
PSU is antec 1000- so plenty of power. I cannot see the post/bios screens as there is Zero output to the monitor- but if I leave it to boot it does go straight to windows. My case doesnt have a speaker and this mobo doesnt seem to either so never get beeps.all power cables tripe checked. Everything has been taken out and re-seated. have tried 2 different graphics cars on all 3 slots.

Just did the cmos reset- no joy.

To repeat- when I first started it it didnt show anything on screen at all- then after a couple of reboots came up with overclocking failiure and went back to defaults and I had display- installed windows, everything was fine, but when i set the bios to optimised defaults the display output stopped again completely.

I have been resetting the bios to safe defaults blind- but that doesnt seem to work. Have reset the cmos using jumper pin- that didnt work. The bios boots, it makes it all the way into windows, but there is no display output from any of the slots or with different GFX cards.
 
I tested my old gfx card and that doesnt work either.

I have just managed to get display back- I unplugged all the hdd's and it booted no trouble. Reset bios to defaults and it is now working fine. The bios is at defaults though and not recommended settings. I am loathe to try and change them again- what the hell is causing this though?

I paid a lot of money to OC for the pre-overclocked bundle. I'd like to figure out what is wrong as my PC is running at a very much sub-optimal level...

Why do the HDDs cause the display to fail when I st it to optimal? Any ideas anyone? I have 4 HDDs- the new OCZ SSD, which works fine, 2 500Gb ones for storage and my old system disk which is a 70gb raptor...
 
I'm wondering if it is the OCZ flash drive. I'm using it as a system disk now and it seems fine, but possibly may need updating. From what I have read though that aint as easy as it sounds if you are using it as your system drive...
