Lost all video

Ok so, I'm at a loss. I have no video whatsoever. I have a MSI Gtx970. I tried replacing it with an old r7 240 that I know works and nothing. Even the on board video doesn't work (tried hdmi and vga.)

I am at a loss here. I know my way around a pc, I built this one myself. And I am totally stumped.
,
I get NADA for video anywhere. I did notice however, that when I turn it on; it goes on for about 1 second, then off for 2 or so seconds, then on and stays on . It was just working fine then froze. It was frozen (I wasn't using for at least 10 minutes) and when I came back it wouldn't do anything.

I have an Asus z97-pro motherboard. I tried to upload a photo but it says it's too big.

Oh boy... tell me I haven't stumped everyone... otherwise I'm SCREWED!

Are you sure it's actually a video problem? Can you remove all of the cards and use the iGPU?

Do you have a PC speaker to set up to hear any POST beeps? Usually a system that won't pass POST won't display any video but will 'look on' since the fans spin and LEDs turn on, but it might not be a video problem.
 
The PC speaker is different than your audio speakers and is just used for diagnostics.

There should have been one that came with your case, and connects to this port on your board:

I'd probably start removing other parts to see if you can get it to POST again including testing with different sticks of RAM and disconnecting hard drives or other peripherals and also resetting the CMOS (which will likely do nothing if you observed freezing behavior before it died completely).

Ah gotcha. Hmm I'll have to see if I can find that. Unfortunately I don't have anymore ram to test it with. The other computers in the house are laptops. I have a sneaky suspicion it's the motherboard. I'll see if I can find that piece for the sound.
 
I can't seem to find the PC speaker :oops:
I am sure it is lost forever. I moved since I rebuilt everything and much of my old PC stuff seems to have disappeared.
 
If you moved you have probably dislodged some RAM. Re-seat GPU and RAM and make sure all is connected including power to the GPU.

Tried that. :( I tried taking out my GPU and tried each stick of ram individually as well. I recently had a problem with my GPU and just got it back from MSI via an RGA. apparently per my wife, it has frozen a few times over the last month. My guess is, it probably did have something lose once I took my GPU out (after the move) and put in an old one. That was when it started, and now that I think about it, it had done it once or twice when left on overnight for my Minecraft world.

I am thinking that all signs are starting to point towards an Motherboard malfunction since I can't even get into BIOS or anything.
 
I had not... I just tried tho... and interesting thing happened.

Every time I turn it on (whether I have unplugged it or shut it of via the switch in the PSU) it goes on for about 1 second, then off for 2-3, then back on and stays on. HOWEVER, when I changed the battery, it went on and stayed on... BUT I can't get it to do that again.
 
It does NOT shut off for a moment if there is NO CMOS battery in it however. It goes on, and stays on but still no video, with video card or with on board video

That happens when the master switch on the PSU has been flicked on and off. Normal behaviour.

Ok so if you're still not posting with a new CMOS battery, could be faulty ram. Try each ram module individually.

tried that. I have 3 sticks of 4GB each. I tried all combinations then tried 1 each. Nothing.

As for the 1st part. It ONLY happens when there is no CMOS battery, or right after it was removed and re-added. I have been trying it with unplugging and with flipping teh switch and always the pause. Unfortunately I do not have the little speaker to try the motherboard POST beeps :(
 
  1. Download the latest BIOS from here and the BIOS update tool from here.
  2. Format a USB drive to FAT32 (important).
  3. Extract and put the contents of both downloads on the formatted USB. Those files and nothing else.
  4. Restart computer in safe mode by tapping F8 on start up.
  5. Follow the remaining instructions from 3-65 to 3-67 here.
  6. You'll need the motherboard support DVD that came with your motherboard.
