Win7 RC Build 7100 x64


I've got a similar problem running the official W7 RC x64 (build 7100). BSOD occurs when my PC resumes from sleep and my monitor is off. Actually, the BSOD doesn't happen until I turn on the monitor. The monitor is connected using a HDMI cable and a DVI converter to a 9500GT. I've tried all sorts of NVIDIA drivers including the ones from windows update. I didn't have this problem in beta build 7000 so I'm beginning to think something changed between the builds.

So, any news on this?

Researching this issue, I came across this. Easy Lai signed off the EC Directives Compliance Statement for this monitor. I wonder if he has posted in Profile Pics.

DDC, Display Data Channel, does support a serial link over VGA (pins 9, 12, and 15). My shot in the dark is this: Using the monitor menu icon shown, disable DDC/CI support - this a comm path from the monitor to the PC, and as such, may have an affect (no, I do not mean effect).

Disable this even if using DVI-D.

windows 7 64 bit and dual boot Pinguyos

Just resolved a similar issue with my setup.
main culprit was the HDMI lead, i have a 3m lead which works fine on all other equipment(skyhd, blurayplayer etc) but on my pc every time i switched sources or the display went to screen saver it would BSOD or not come on again or force a restart. changed the HDMI lead and all was fine.(for now).
It seems that some leads have an issue with power supply so that when your video card switchs to a low power state and then when you want to wake up the monitor it cant because it cant find the correct power supply(switching the monitor off then on again sometimes works)this is due to the lead not carrying the power correctly either because the lead is too good(sounds daft i know) or it has an internal problem, apparently most other TV, bluray etc, dont rely on this so much as they are permanently in a high power state, also the longer the lead the more likley the problems, i know this after spending a large amount of time in various PC stores(the consesus was that HDMI/dvi is still not properly supported), Electrical suppliers this morning, i ended up buying a 3m lead from Lidle for 4.99 works fine, my 80 monster cable was a no go.

I also rolled the video driver back to the original install driver and didnt use the update that windows update downloaded after my install.

Hope this makes some sense.
