Win7 Ultimate x64, BSOD when waking up from automatic monitor shut-off

I put my 7870 in the old computer, letting windows install just the basic driver. *it does the same thing*. PC goes idle, fans turn off, lights turn off, every minute or so they pop back on for a few seconds and then go off again.

Your 7870 card is bad, as it behaves the same for another one PC. You need to replace it.

Yeah, thats what I figured I'm apparently not the only person on newegg who has had their bad card replaced with another bad card. I'm just gonna ask for a full refund and go with another card entirely, and steer clear of MSI in the future.

Thanks for the help.

*Sigh* Apparently two faulty video cards were a totally separate issue from the freezing when idle. I just put a totally different, brand new Gigabyte 7950 in it. I did a complete driver wipe before installing the card and reinstalled from a brand new download of the drivers from the ATI site. This card works great, but I just froze when idle and managed to get it to BSOD again with a DRIVER POWER STATE FAILURE just like before. Attached is the dump/logs.

Just did it again, within 10 minutes of the same time it did it last night. I'm starting to think some software is scheduled to autoupdate or something at ~10pm and causing some sort of driver conflict.

sfc /scannow found no issues.

I've already replaced the DVI cable twice since the OP with no difference, and the monitor has worked perfectly fine for years with my other PC. Right now I don't have another monitor to test it with, but we'll see if it crashes again tonight like it has the past two nights.

It didn't crash last night at all, i'm totally stumped on this one too. Even ran an sfc /scannow to check the integrity of my windows install and it came back clean.

The odd thing is that sometimes when it does it I just cant force it to bluescreen, it hangs in that state indefinitely. The windows event viewer keeps recording events while its in that state, you can still access files shared from other computers. I did also notice that the NIC on this motherboard apparently defaults to using IPv6 despite the rest of my network still using IPv4, though I doubt that has anything to do with it. I get a lot of Microsoft Security Client OOBE errors too, perhaps Microsoft Security Essentials is causing the instability?

Windows Update: Currently set to check for updates daily, usually occurring between 6 and 8PM. All updates have been applied.

IE9: IE9 is already installed, and I use Firefox for everything that doesn't absolutely require IE to work.

I've run Chkdsk on both the SSD and the HDD multiple times worried that there was disk corruption from all the crashes, it never found or repaired anything. I'll try Seatools today on both drives.

Each time i've had to remove/replace the video card (I think we're up to 3 or 4 now) I've completely disconnected and reconnected all power cables :/ I'll reseat them again.
