Hi Deadmano, were you able to fix your issue by adjusting TdrLevel or by any other means? I have similar problems with my 5080; my PC never crashes unless it wakes up from sleep (not hibernate). When I wake it up, I see the fan spinning but no signal goes to the monitor. Yesterday, I unplugged my display cable after I got a backscreen and plug it in my motherboard and I was able to get a signal, so it was the card that failed, but a few minutes after my whole system froze.
Hey! Thanks for the reminder, I actually wanted to update this thread in the event anyone comes across it via a search!
So my issue, FINALLY, has been resolved, or at least, I want to believe it has, since in over 2 weeks I have not experienced the dreaded freeze I mentioned throughout the thread.
I haven't tried any hardware changes, no reseating, no software reinstalls (no Windows updates/reinstalls) etc. Literally the only changes I've made last were;
- TdrLevel set to 3. (Enabled). It was previously 0 (Disabled) by default for some reason.
- TdrDdiDelay set to 10. (Default is 5).
- TdrDelay set to 4. (Default is 2).
One thing I noticed that didn't seem to occur before, is that after resuming from hibernation I will get a temporary freeze of 1-2 seconds, and then not again until the next resume from hibernation. My assumption is that is what would have been the hard freeze that causes the system hang, but TDR is preventing that? I thought a message pop-up was meant to appear when that happens, but there's no notification, nothing in the event viewer. This could all be purely speculative and perhaps nothing has changed, but I've been using the system the same, gaming about the same, with the same titles, and no hard freezes since then touch wood, even in the VR game which was causing me issues every time, no hard freezes in 3x 3+ hour sessions over a 2 week span.
