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!
 
Sounds like your going to have to reset the cmos properly and manually setup the bios.
remove the battery and put a jumper on the clear cmos pins. Using a screwdriver may not give a reliable connection for the full 30 seconds.
 
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!
 
Try removing your ram and booting. If it posts then it's a ram setting most likely.

I had exactly the same thing once when the settings for my ram went screwy.

EDIT: no I was thinking of a different situation, actually when it didn't post the ram was faulty. But it could still be the settings.
 
Is the BIOS still at defaults?

Try removing everything off the board but the CPU and cooler and then boot it. If if you don't get anything at all (I would expect a disco of beeps) then something is seriosly screwed up. I have never had a bios completely refuse to boot without at least something in the way of a clue or defaulting itself or something.
 
What PSU do you have ? Also make sure in the BIOS to set all to defaults (No overclocks) and set the BIOS to boot from the PCI-E card 1st. Try reseating the expansion cards and memory. Also make sure your monitor is set back to defaults if you fiddled with any of it's settings and make sure it is using the correct input and the correct refresh rates. Also make sure all power cables are in and tight, for the motherboards (2 cables normally 1 for CPU and motherboard) and make sure the graphics cards have both the 8 pin cables in correctly for that card. Also try the graphics card on a different PCI-E slot to rule out a bad PCI-E slot. Also if your monitor supports HDMI or DVI or VGA try these options too, but you will want to have it on DVI as your main setting for daily use.

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.
 
Can you try the graphics card in another machine ? That way if it works you can rule that out. Also do you have another graphics card you can test on that pc ? That way you can rule out bad motherboard , cpu, ram and PSU. But again you can never rule out a PSU they sometimes seem to work on different setups fine and fail on others.
 
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...
 
Maybe go threw your HDDS and find out which one is causing the fault, it may need a firmware flash. Does the pc boot up at the OC overclock without the HDDS in and only the SSD ? If it does then plug one drive in at a time and test to see which one causes it to fail, it may also fail due to the amount of drives plugged in so test for that too, don't persume the drive you just added made it fail. I would then unplug all drives and test the one that made it fail, if it still fails with only that drive in and the rest work fine, it means you have a bad drive or it needs a new firmware, also make sure to test on different sata ports on the motherboard and only use the Intel ports for now.
 
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...
