Hey guys, I received my Asus Xonar Essence STX yesterday, but I am having problems with it. When I cold-boot with it in my PC, regardless of which of my three available PCI-E slots it is in (two are 1x and one is 8x), I frequently get either (i) no signal to my monitor, which stays on standby indefinitely until I reboot or (ii) sometimes the PC will automatically reboot in scenario 1 although this has only ever happened with an OC, after which my bios tells me that my overclock caused system instability (yeah, right; I just tested my OC a few weeks back and it was rock-stable). (iii) If not the previous, then a BSOD after a short hang at the Windows 7 boot logo. After I have cold-booted though, I can usually get into Windows and install the driver, and once the driver is installed, the card works just fine in Windows... But even with the driver installed, it will often exhibit the above symptoms if I cold-boot (i.e. if I disconnect and reconnect the power plug into the wall socket and then boot). Occasionally, my PC will also BSOD or not give a signal to my display if I simply reboot from Windows. I first thought it might be a bios problem, so I reverted my bios settings to defaults (which included removing my CPU OC) but that did nothing to resolve the issue; even without an OC, this behavior still happens. I then thought that maybe it is due to a bad power connector or something so I switched around my cables and that, too, did not solve the issue. I also tried re-installing the ASUS driver four times after each PCI-E slot change (did I mention that I tried every available PCI-E slot?), but that did not work either. Finally -- and this next part is what makes me almost certain that the sound card is defective -- if I remove the soundcard from my PC, then with or without the driver still installed, none of the 3 problems described above occur. In other words, if I take the Xonar out of my PC, everything works exactly as normal (although I haven't tried with the OC). Is my STX faulty?? I just want a second opinion before I request an RMA because I bought it from an online store and the RMA process will take a long time if I send it away. Any suggestions for further troubleshooting or is this pretty clear? Below is a screenshot of BlueScreenView. The crash address is always the same and so is the bug-check code and the faulting address. However, I don't know how to read minidump files so I can't interpret the information I'm seeing in regards to pin-pointing where the physical fault lies if anywhere.

And before anyone asks, yes I connected the 4-pin power connector to the card, and yes, I have uninstalled every other audio driver from Windows (incl. ATI HDMI audio) and disabled Realtek ALC889A from bios.
