Okay, here's the deal: I've been searching all over the internet and this seems to be a common problem but here goes anyway...
My system was running wonderful! (specs are below) All was well with all my new stuff; I was modding my Skyrim game having a grand ole time, when all of a sudden, one day, it just wouldn't wake from sleep mode. Well, it would wake, I could hear the fan start spinning, but there would be nothing on the display. Also, if I happen to turn my system on before turning on my display (which is my 42" JVC TV) it will have no picture at all. I've done nothing new, at least that I can recall. My video card is NOT on auto update, I check it myself and update when I feel the driver is stable enough. (In my personal opinion, I think NVidia puts out new drivers too often. I don't think it's necessary just for the optimization of a few new games, or for TWITCH or some such nonsense when it doesn't apply to me).
I am getting concerned about having to do all of these hard shutdowns so often. So now, I have to shutdown each time I'm going to be away for awhile. BIG pain!
I have tried all the different configurations in POWER SAVING menu, including custom: Sleep: never, Turn off Display: never, Hibernate: never, etc. (I even made sure to tell my television not to turn itself off). I checked the bios, it's all good there. I went into Device Manager, checked that all USB Root Hubs were unchecked as far as "Allow the computer to turn off this device to save power" so the ports would stay on, so that my mouse and keyboard could be used to wake it. Checked the mouse and keyboard; "Allow this device to wake computer" all checked. So as you can see, I have run the gamut on this issue; all to no avail.
Does anybody have any idea why this would just stop working all of a sudden? I REALLY hate Windows Auto-update. Mine is set to "notify me and I'll decide what to download and install" . But believe it or not, these (beeps) at Micro$oft somehow manage to slip an update in there on me now and then and I can't figure out how. At any rate, I'm finding lots of sneaky little crap with this OS. Things that were taken away that were available before, along with other things that were slipped in that I don't need or want. Now I find that this is VERY common problem, and something that been going on a long time with past iterations as well. I'm starting to wonder if an update somehow did this.
Now that I'm done Micro$oft bashing, does anybody have any ideas? Or maybe some info regarding something I could have overlooked? I'm no computer wiz, believe me, but I can GOOGLE and I can read and I. Am. Learning.

The issue is essentially an inability to wake the computer from Sleep/Hibernate mode, I have found that this can be a bit unreliable at times it's not something I use on a desktop.
Form my perspective these modes are not entirely useful for desktop computer they make sense for a laptop since during startup a laptop can consume quite a few watts from its battery. Generally Hibernate and sleep are things I disable on desktop, however if you are using anything other than an SSD the startup times can be a pain!
I agree that these things are not very useful tools for a desktop. But, as you say, Agam3mn0n, startup times can be a pain, and this is one of the reasons why sleep mode WAS a useful tool to ME. I can just use the screen saver to make sure I don't get any "Burn in" on my lcd screen televion. But I still have this problem: if the display is for some reason turned off, the screen goes dark. If I then turn it back on or move the mouse, the fan whirs, the system wakes up, but the screen REMAINS dark. This just does not seem like something I should just let be, considering that it just started happening out of the blue. The worst part is, that if the mouse gets bumped (quite often by my cat, Kevin), sometimes a program will start and we don't know what it is and can't see to close it or turn it off. I would really like to get to the root of the problem and use sleep mode once again. These types of mysteries drive me to distraction.
Thanks for trying to ease my mind Agam3mn0n, but my search will continue...
Mmm, the display detection issue could be a hardware fault in the card. if it is not detecting the display then it won't put an image on it. It might be worthwhile permitting your computer to get an updated display driver from Nvidia (you can of course prevent it from downloading Beta drivers. Since most driver revisions solve bugs and include profiles for new games (this is why they are released frequently).
It is possible that an updated driver may solve that problem. If not it could be a hardware problem, with either the display or card, if you have another display you could try the card out with it, otherwise it may be possible to RMA it if you get the same issue on a different display with an updated driver..
