Hi guys.

I have recently built my new rig and everything was working fine. However now when I turn my computer on everything seems fine (I can see the BIOS etc. Can change settings) but as soon as the graphic drivers kick in (after the Windows floating orbs loading screen) both of my monitors (hooked up by DVI) go black and say "No Signal".

I can boot successfully in Safe Mode and the screen works okay. And I can log in when I boot normally (I can hear the sounds), my displays just don't turn on.

Any idea's?

At the minute, my plan of action when I get home is to update all of my drivers.
 
Full system specs?

In safe mode, uninstall the graphics drivers with Device manager, then try the latest ones.
 
Here are my current system specs:

2x Samsung HD103SJ Spinpoint F3 1TB Hard Drive SATAII 7200rpm 32MB Cache - OEM
SAMSUNG 128GB 830 Series SSD - 2.5" SATA-III
OCZ 60GB SSD SATA II
Intel Core i7 3770K 3.5GHz Socket 1155 8MB Cache Retail Boxed Processor
Asus P8Z77-V Socket 1155 VGA DVI DisplayPort HDMI 8 Channel Audio ATX Motherboard
Antec Kuhler H2o 920 - Mainstream Cpu Liquid Cooling In
Corsair Vengeance 16GB (2x 8GB) 1600MHz DDR3 Memory Kit
NVidia GTX 460 Cyclone (768MB)
OCZ 600W Modular PSU (Can't remember exact model)
 
Left computer on last night and went to bed. Screens went to sleep (Computer didn't) and the same issue occurred. The screens would not turn back on; this continued upon reboots.

I have checked my motherboard and the default graphic device is on "Auto" I change this to PCI/PCIe and when Save and Reboot, I check again and it's back on Auto.

I'm wondering if this is the issue? When I get home from work tonight I'm going to boot, if the screens don't respond I'll unplug one and put it in the on-board DVI connector to see if it loads on that one (I'm thinking Windows might be thinking the on-board graphics are set as default?)
 
The on-board DVI connector works fine.

I did a logged boot up and it is definitely the NVidia drivers crashing (or conflicting with another driver) as they fail to load.

I have tried several different versions of drivers now and believe it's just a conflict in one of the other drivers.

Going to try installing the drivers one by one tonight and see exactly which driver is causing the grief.
 
I've had a couple of black screen screens brought to me over the last 3 or 4 months. All have been power related.

Try re seating the PCI-e power cables and if you can, check they are supplying adequate power by taking readings from a multi-meter. It might also be worth testing your system without un-essential devices, like disconnecting all your supplementary HDDs except the one with the boot partition. If that works fine, then start connecting them one by one.. If the problem re-occurs, then you have exceeded your power requirements. The test will at least illiminate power for the time being.



Are all your other BIOS settings being retained from a cold boot?
 
I had a similar problem I initially thought that it was my monitor+displayport or driver problem that was causing the issue as it is a known problem (Samsung S27a950d). However it turned out to be bad bios setting somewhere, I removed my GPU's did a bios reset and reinstalled the drivers again as a matter of course and we have been good ever since.

Yes all other BIOS settings are being retained. I will try removal some stuff tonight just in case of a power issue.

Thanks
 
After hours of trying different things this is finally "working".

I tried a different graphics card in the x16 PCIe socket and it worked perfectly fine, rebooted several times with latest drivers. So tried my card again and it didn't work.

I then tried my card in the x8 socket, installed drivers and it was working fine! It still is working fine, and I'm not quite sure what would cause it to stop working in the x16 socket (As it's x16 capable) but at the minute I'm just happy it's running at all.

I know no GPU can actually use the full potential of x16 right now, but does anyone have any idea why this might happen with just my GPU and not a spare I had lying around?
