When Turning Off Computer & Turning It Back On Again Screen Is Blank

Dec 31, 2012

when my computer goes to sleep after it's on for a while when I move the mouse to get the screen back up it shows the backround no icons or anything to click. Same if I turn it off and turn it back on. I have to turn it off and on many times then go to safe mode and shut down then turn it on again for it to work. Just now I had to turn it on/off 4 times for it to show the icons and task bar. Usually it is left blank with nothing to click having no choice but to turn it off. Norton says no viruses. My computer is HP with windows 7. I bought it in 2011.

Monitor Stays Blank When Turning It Back On

Dec 16, 2009

I am going to preface this by saying that this has *nothing* to do with restoring from sleep or hibernate modes. In searching for an answer to this issue, I found way too much related to that.

My problem is simple. Occasionally (~50% of the time) when I turn the monitor back on after shutting it off, it will stay blank and not really turn back on. It makes no difference how long the monitor has been off. After turning it back on, the power light is green, indicating there is a signal, but the screen is black.

Again, the computer has not slept or hibernated. I simply shut off the monitor and later come back to turn it on. The same thing will happen occasionally if Windows shuts the monitor off after the configured time. (I did that last part as a test; I typically do not automatically shut it off.)


OS: Windows 7 64-bit

CPU: Intel Core i7 860

MB: Asus P7P55D

Memory: 8GB - Corsair CMX6GX3M2A1600C9 (2 x 2 x 2GB)

Graphics: NVIDIA GeForce 8800 GTS 640MB

Monitor: Chimei CMV 221D

NVIDIA Drivers: (11/20/2009)

I originally thought it was the OS that was hung. However, I was able to go into the start menu and restart ("Start" -> "Right" -> "Right" -> "R"), so I know the OS was there responding to my commands.

Attempts to fix:

- Restart the computer. This worked.

- Shut off the power to the monitor and turn it back on. This works most of the time.

- Lock and unlock Windows. This works after a few tries.

- Hit CTRL-ALT-DEL followed by ESC. This works after a few tries.

So, I have a fairly simple work around now. So this is only a minor annoyance. Hitting CTRL-ALT-DEL then ESC does seem to work. I don't think it is a placebo because I waited 5 minutes and it did not come back, but after 2 cycles of that, it came back. I think that fixes it because it causes full screen refreshes.

Does anyone have any ideas or has anyone seen this before? The drivers are recent, but I noticed this with the clean-install Windows 7 drivers for this card as well. This is a very clean and very recent install (3 days). I never had this problem with Vista 32-bit, the same graphics card, recent drivers, but different CPU/motherboard/memory.

No Log-In Screen When Turning On Computer

Dec 16, 2012

Today I have been experiencing some problems with my computer with trying to turn it on and I am noticing 3 things that are unusual

First of all, I am noticing that when it turns on, there is no where for me to log-in. The blue background shows up like normal and I have a cursor to move around so it is not frozen-just no user image and nowhere to put in my password. Also, I am noticing that the size of everything on my screen (what actually shows up), is larger than usual, including the cursor which is much larger than normal.The last thing that I am noticing when turning on my computer is that if I leave my blank screen sit for a minute or two, it will automatically start to restore the system, so I don't know why it would be doing this if i never made a command for it.

Turning Off 1 Screen Disables The Other Too

May 2, 2009

Just installed 7100 and was setting up. I have a Toshiba HDTV on DVI (display numbered 1) and an Acer lcd on VGA (labeled 2). The acer is set as the primary display and all appears fine but when I'm not using the hdtv I'd like to turn it off and just use the lcd. When I turn off the hdtv I hear the sound for disconnecting hardware and the signal is cut off from the lcd putting it to sleep.

I tried the latest nvidia drivers (oh yeah, 8600GT) and it made the system super crashy with bsod's and everything. Can I disable plug and play, which I suspect is the problem, on just that monitor?

Screen Keeps Turning On/waking Up By Itself (Windows 7)

Dec 29, 2011

Windows 7 laptop set to turn off screen after a few minutes of inactivity using Windows 7 power options. Sometimes the screen turns on/wakes up while in this state seemingly randomly for no reason.

It's running an Opera session, gadgets for weather, CPU monitor, and calendar. Sometimes runs other apps but that doesn't seem to affect this behavior at all.

No notifications pop up when this happens, no errors. No viruses, CPU usage is very low (single digits). No new applications installed, nothing really installed besides windows updates and Opera update (this didn't change anything). Nothing obvious changed since before this started happening besides these updates. No graphics driver updates. Windows 7 install is about 5 months old.

Computer Turning Itself On During Night

Sep 13, 2009

Just wondering if anyone has any solutions to this other than a complete shutdown.

I place my computer in either stand by or hibernate and for some reason in the early ours of the morning it will turn itself on and sit on the login screen.

I think it must be some kind of back system operation which is sheduled but I have no idea what or where to find it.

Any ideas?

No Bootscreen When Turning On Computer?

Feb 19, 2012

I recently built a new rig and have had no problems so far, but just the other day (even up til now), when I turn on the computer I do not see the standard post screens or even the Windows 7 loading screen. However my computer DOES boot into Windows 7 just fine and everything works as usual. But this is bothering me because if I need to make any changes to the BIOS I can't. Does anyone know how to fix this? To clarify though, computer is not hooked up to a monitor, but to an 32" Toshiba LCD TV. It's been hooked up this way since I built the rig though.

Computer Keeps Turning Itself Off And Also Resetting Date And Time

Nov 7, 2012

The problem I am having is that whenever I log onto my computer, I can see that the date and time at the bottom right of the screen always seems to reset to 31/12/2006. I always try to fix this by going to the option where you can synchronise the date and time with the Windows server time, however, this doesn't always seem to work.Another problem I am encountering is that the computer itself seems to be cutting out at different times, for example I could be 98% complete into a full system scan with Kaspersky 2012, but the computer suddenly cuts out, this would also be the case when browsing the internet or completing some Word documents. One other thing to mention as well is that since these problems have occurred, whenever I turn on my computer, I never have to press the power button on, as it seems to turn itself on whenever I switch the power supply on. This is also not normal.

Desktop Computer Turning Off, Won't Stay On Very Long Either

Jul 16, 2012

Windows 7 64 bit. Installed win 7 professional fall 2010. Service pack 1. Intel (R) Core (TM) 2 Quad CPU Q965 @3.00 GHZ

Had trouble with computer in March 2011 and eventually had to ship to HP with extended warranty (which ran out march 2012). They installed new motherboard and RAM. We upgraded fan (there are 2) and took RAM from 2GB to 8GM in May 2011. Has been running great, no problems til this weekend. It will shut off like being unplugged. I can't get it to stay on very long before it does it again. I am getting the sign on screen and the desktop shows up. I can do about 1 minute of operations before it goes out.

Opened up the tower and the fans are running, nothing feels hot.

I believe it has to do with hardware, I am going to try replacing the RAM. Then checking the fans.

Mouse/Keyboard/USB Don't Work Anymore After Turning Off Computer

Nov 12, 2010

Yesterday night I turned off my computer by pressing the power button and now my mouse and keyboard do not work anymore(in Windows). I wanted to see if it was just the mouse/keyboard itself, but I noticed nothing detects when I connect a USB device. I tried plugging it in every port and it's the same. I thought it was a hardware issue, but now I realize that it is not.

I restarted my computer and tried to get into safe mode; it worked(I was able to go up and down to select which mode I wanted to enter). Once inside safe mode and windows is loaded, the keyboard just freezes. It does not work at all. I then decided to go into bios to see what is up and everything seems right. I even screwed around and messed up my overclock settings.

So now I know my keyboard still works and it's probably a Windows issue. I wanted to see if my mouse would work. I went into Windows Repair(I might have gotten the name wrong) and voila, my mouse worked!

Receiving "no Signal" Upon Turning On Desktop And Occasional Screen-freezes?

Sep 19, 2012

i recently got a new dual-monitor desktop built by a friend and it worked fine for the first week or so. a few days ago it started getting hectic whenever i tried to turn it on, in that it would frequently do one of two things:

1) the screens would both go black and post "no signal"

2) both screens would freeze in place and it would recognize no actions aside from turning the desktop off the "no signal" issue only appears when attempting to log in or right after turning the computer on, whereas the screen-freezing would happen at any given time, whether it be logging onto the computer, checking facebook, or playing diablo iii. it currently takes me 3-4 attempts to get it running properly each day. everything in the computer is new, so it shouldn't be a problem with bad cables connecting the monitors to the tower or the ports that the cables are connected to. i've tried moving the cables to different ports on the tower, and it doesn't really seem to be affecting the problem. nothing is out of place or unscrewed inside the tower, so it's probably a software issue. the same friend that built the computer suggested that i get the latest nvidia drivers since the most recent ones were available on the 14th, whereas my current nvidia drivers are slightly older. i tried downloading the most recent one, but then i received the screen-freezing problem. whenever i attempt to download anything video-related online, the comp simply freezes up again. i can play Internet videos and diablo iii fine, just not download anything significant off the internet. my friend tried working with the comp as well, but he's at his wit's end and suggests that we get outside help in diagnosing the problem, so he recommended this site.

computer specs are as follows:

windows 7 ultimate (service pack 1)
intel core i7 cpu
64-bit os
x2 gtx460 video cards
12.0 gb of ram
