"DVI No Signal" shows on my monitor whenever I turn on my computer, but works after I restart it.

I built my computer back in January, and I've had this issue for a while now. I would turn on my computer (usually for the first time that day) and get a "DVI No Signal" on my monitor screen. Then, I would turn off my computer, turn it back on, and everything would work just fine. The problem went away for a month or so, and then came back. Any ideas what's wrong? It's escalated to the point where it happens once I wake my computer up out of hibernate mode, and I now have to restart my computer twice in order for it to work, and it's incredibly annoying. I changed the BIOS to default to PCIe (PEG, correct?) instead of onboard graphics (and I disabled the onboard graphics as well), but it doesn't seem to help. Here is what I have:

OS: Windows 7 64-bit SP1
CPU: Intel i5-3470 3.20GHz
Monitor: ASUS VH238H
Motherboard: Gigabyte GA-H77M-D3H H77 1155 R
GPU: MSI R7870 Hawk 2GB

Any ideas what's going on? Thanks!

  1. Can you try a different card to determine if it is card or MB related? Maybe try a different DVI cable as well. I'm assuming the signal is DVI to DVI with no adapters in between.

    And yes, PEG is PCI Express Graphics.

    I only have one graphics card, so I don't think I'll be able to switch mine out. As for a different DVI cable, I only have one (when I built my computer, I didn't think I would have an issue like this).

    If it's of any help to you, my previous monitor only had a VGA cable. I had to use a VGA to DVI adapter, but I still had this same problem.

    Until you know what device (MB or Card) is presenting the problem, it is going to be mostly guesswork. You could try updating the MB BIOS and the Gfx Card's BIOS. At present, I'm leaning toward it being a MB issue. I was going to suggest that it could even be the monitor, but since you say this problem occurred with a different monitor/cable, it's not likely that is the issue.

    1) Does this happen with the card in the other PCIe X16 slot?
    2) Does this occur with the gfx card removed and the monitor connected to the on-board DVI?

    I'll update my BIOS's to see if anything is fixed. As for actually going into my computer and changing things around, I'm not going to have the time to do that until next weekend, unfortunately (school and stuff during the week and all that jazz). I'll shoot you another reply if none of your methods work. Thanks for the help! I'm crossing my fingers that this isn't a hardware issue.
