Everything works, but monitor not picking it up!!!

[Eric_Milburn]

I recently built a system with the rampage IV extreme with an 17-3970x processor. The machine worked great, while i was loading drivers, but when i shut the machine off and rebooted it, the monitor doesn't seem to pick any signal up. I hadn't moved the gpu (gtx 690) and i never touched any cords. Need help!!!

When it boots up watch the drive activity light (if you have it connected) to see if it seems to be proceeding through the boot process into Windows. If it isn't doing anything then it could be there really isn't any output. If it seems to be booting then try different display outputs. It's possible that for some reason the display is out to another port. And just because you didn't touch anything doesn't mean something wasn't loose and worked its way out so I would disconnect and inspect all of the connections.

Just for the sake of completeness I would also hook that monitor up to another source and see if you get a picture to confirm that the problem is with the machine and not the monitor.

There is a VGA led that is lit red that I haven't seen when it was working. Could this have something to do with it?

[xeromist]

Possibly. I would reseat the power cables from the PSU and the GPU in the slot. You might also want to remove all but one stick of memory and see if it will POST. You could try moving the card to another slot and also make sure that the slot switch didn't get set to disabled for some reason.

Thing is all graphics cards (2x 690) are lit up meaning their on, but im still not getting any kind of response

You have two cards? You might just have a bad card or SLI bridge. Use the slot switches like Menthol mentions in the next post.

EDIT: better troubleshooting option below

Which VGA led? Are the pcie lane led's lit yellow=normal. A red led would indicate a problem, usually power related, maybe to many cards on one lane of a multi-lane power supply. You're monitor should be connected to the DVI output of the top card and I believe the top dvi port of the top card. The pcie lane switches are a very good trouble shooting tool when using multiple graphic cards. you can turn of pcie lane switch to the top card to run the second card as single to test without removing cards and swapping them

[Eric_Milburn]

The light is yellow, and the red vga led is by a group of lights grouped as boot drive

Hm... "The machine worked great, while i was loading drivers, but when i shut the machine off and rebooted it, the monitor doesn't seem to pick any signal up." - so things got worse when you installed the Nvidia drivers, right?

I'm curious how big PSU are you using for 2x GTX690?

Can you still go into BIOS? If so, then you could try boot into OS in Safe Mode and remove the Nvidia driver... then re-install it again... - which driver have you tried to install?

Pull the SLi bridge from your cards and see if your system works with one card.
