![]() ![]() I know there are tons of other causes (SSDs, motherboards, etc.), but I'm hoping I've found a simpler but less well-known cause. I'd like to hear opinions on whether that is a possibility.Īnyway, this is more or less a Public Service Announcement for people having trouble with blue screens tied to sleeping the computer. That led me to ponder whether running HDMI from a graphics card with onboard audio (i.e., all modern graphics cards) to a monitor without sound capabilities might have been the cause. The cause(?): My hunch is that all of this started after I replaced my DisplayPort cable with a spare HDMI cable a few months ago. It's going to take a few days of sleeping/waking to see if I've actually found a solution, so I'll update this thread with what I find. ![]() My next step, which will have to wait until my Monoprice DP cable arrives, is to pull the HDMI from my system all together and avoid any potential for an HD audio driver to be engaged due to the presence of my nVidia graphics card. ![]() I found, however, that Windows then automatically installed the generic HD audio driver upon reboot, so I simply disabled that audio device. First I uninstalled the nVidia HD Audio driver. The resolution(?): I have taken a few steps to resolve the problem, and I'm doing further testing to see if I have indeed found the culprit. I am currently using an HDMI cable, attached to a monitor that does not support sound (hint, hint), after having broken my trusty DisplayPort cable that I'd used for many years (connector bent out of place). The culprit: Using a developer-oriented program called Microsoft Debugging Tools ( ), I've determined that all of my blue screens have been caused by the nVidia High Definition Audio driver (nvhda64v.sys), which is part of the main nVidia GeForce driver suite. So I decided to do a bit of diligence on the handy file called a "minidump". At first I thought it was my undervolted or overclocked CPU (depending on usage scenario), but resetting to stock hasn't changed anything. The situation: for the past few months, my main rig has been bluescreening about 1 out of every 3 times it wakes from sleep, but never during use. Just thought I'd start this thread as I troubleshoot a problem that others might be having, and get insights on why it might be happening. ![]()
