Yesterday i bought new grafic card geforce GT440 after my old 9800 GT stoped functioning normaly(memory failure). So here is the problem, when I start any program or do anything the computer the computer is functioning normally, but when I turn to desktop(which has black wallpaper) the monitor goes so dark that I can't see almost nothing. I tryed to find some power saving options in windows(win 7 pro, 64 bit) and on envidia control panel but i cannot find any cause for that dark screen. Even if I load a black page on my mozilla the monitor goes dark. As it cannot represent dark colors normally.

View 3 Replies View RelatedOn my monitor it seems like everything is too bright, as in places that should be pitch black are a bit too light. For example: on my iPod, even with full brightness settings everything looks normal, but on my PC's monitor it just doesn't look right.I calibrated color and setting gamma way low really helped, but my contrast is set to full, and my brightness is 75.The strange thing: when I ran Crysis 1, it fixed the monitor color! So I know the darn thing is capable, I just don't know how to.When I closed down Crysis it went back to normal.

When the screen goes dark, I have to move my mouse around to get the screen to come back on which it usually does. After a few minutes of doing this, my screen stays on. I am running Windows 7 Ultimate 64 bit. I do have McAfee anti-virus protection. I just recently ran a virus scan which came up clear of any viruses. I also tried adjusting when the screen goes dark
View 1 Replies View RelatedI have a 10 month old Acer 5820t laptop running win 7 home premium. About 6 weeks ago, the screen started going dark every few minutes and it has gotten worse. I can see the image faintly and by pressing the display brighten button can get it to come back or sometimes have to close and reopen lid it will come back. No external peripherals are connected. The Intel HD graphics card has the latest driver installed. The screen saver seems to work but the display will also go dark when the screeb saver is running.
View 1 Replies View RelatedI have installed the latest drivers, reinstalled the program, and all that jazz and the problem still persists. Pretty much when I minimize or exit from a game I play called EVE Online, my LCD remains really dark. Kind of as if someone turned down the brightness really low on the LCD. I've figured out 2 workarounds but they aren't fixes.
I simply log out and log back in and the display brightens to its usual brilliance or I hit Ctrl+Alt+Del and it has the same effect. But once I maximize the game and minimize again the screen darkens once more. Oh and in-game everything is perfect, it's only once I go to the desktop. Any ideas? I personally think its a something wrong with the refresh rate but I ahve no clue as to how to fix that.
I have attached my DxDiag results.
During the day, if we leave the computer alone, screen goes black, after a while, fans turn off. Wireless mouse wakes it up just fine. Fans startup before the screen is completely ready to go. During the night, the screen is dark, but the fans almost never stop. Why?
View 9 Replies View RelatedIf I let the computer sit unused, the screen goes black, as most monitors would; however, the screen stays dark when I move the mouse or hit buttons or something. Similarly, if I close the lid of my laptop when its turned on, and then open the lid, the screen stays black. Not only that, but when I closed the lid of the laptop, the computer never turned off. It was still running.I reset the power options to default as well, so there is nothing wrong there. Perhaps I should also mention that the screen successfully turns off and on in safe mode?
edit: Just tried a system restore to two weeks ago and the system crashed. Both times.
i havent had my laptop long but i was on it one day and it crashed on me and my screen went dark, then it started making a buzzing noise.

View 2 Replies View RelatedI recently built a new pc and installed seven as my os. I couldn't help but automatically notice that the screen dims to darker images... I have never had this problem before with my monitor. I knew it had to be a seven feature.. Yet I can't disable it... I've tried hardware device options and power saving options... This is a stupid feature... Why would you want to Dim the screen on an already dark image....I cannot play certain games because it gets way to dark to see anything.
View 2 Replies View RelatedI built a new PC about a month ago. BioStar A880GU3 and an AMD Athlon II X3 455 CPU. Also running Windows 7.
I set up two monitors and have them set to extend. Everything has been great up until about a few days ago. One morning I turned the PC on and my 2nd display was totally black. It was turned on and Windows was detecting it but I couldn't see anything. I drug a tab from Firefox over to the monitor and dropped it and the screen started flickering and eventually came on. Everything was cool for the next two days.
A few days later, it happened again. This time, I could faintly see that the screen was on just very dark because I could see the outlines of the Firefox window I drug over there. Now it happens every time I turn the PC on. It eventually stats flickering and comes on on it's own and stays on until I shut the PC off again.
I also can't even see the monitor's menu when I press the menu button on it. Does this sound like an issue somewhere in Windows, or just a failing monitor? It's a bunch of years old and was sitting in my basement for over a year until I built this new PC. I'm just curious because it worked fine for weeks after I started using it again.
Once, I saw the startup and shutdown used a black startup/shutdown with like gray or silver graphics..not the usual wimpy pale blue.
No idea how I did this--anyone else seen a different version like myself?
I am using the system spec as shown in the signature. Both monitors are connected to a single ATI 6870HD. The Dell U2311H is connected to the card via minidisplay-display port while the LG M227WD is connected via the DVI cable. The problematic monitor is the monitor over the display port (Dell). The monitor goes black randomly, sometimes during I play games. Sometimes it goes black more than few seconds, and I get a message on the screen saying power down as there is no reception from the display port.
I have updated the latest drivers, but still this problem persists. A
When I start my PC up a line of red dots appears across the monitor screen at the bottom of it. The line of dots again appears but higher up the screen when the windows screen appears. Both screens are dark in colour. Also if I have a block of dark colour anywhere with a light coloured background about 3 or 4 lines (each line directly above the other) of red dots appear across most of this block of a dark colour but none in the light coloured background. In all cases the red dots do not form a continuous line across the screen. My pc has an Intel i5 3570k processor running at 3.4GHz (not over clocked) with onboard intel HD4000 graphics. I do not have a separate graphics card.

View 2 Replies View RelatedI have a new HP dv6 laptop. The operating system is windows 7, 64 bit. I've had it less than a week. The power option I have set on it (default) calls for the system to go into the sleep mode after 20 minutes(closing the lid). I don't even see any option available to select that would shut the computer down after a certain time. The problem is, after having not used the laptop for approx. 12-14 hours, when I am ready to use it again, it has shut itself down. I don't know why it doesn't stay in the sleep mode.Any ideas why the laptop is shutting down? It's not overheating because I keep it in a cool room and the air flow around it is not restricted.
My Windows 7 hung itsself up this morning. I had to use the power button to restart. I chose Safe Mode. I now have the screen:
Start up repair. Start up repair is checking your system for problems Attemping Might take an hour
That was 8 hours ago and it is still running. I pressed the Cance button and got the answer "Cannot cancel"
Previous Windows OS's let me quickly and easily restore to a time that I wanted, however what I'm getting with 7 is "no restore points have been created". Hmmm. I've searched this forum for an explanation that makes sense to me to no avail; not yet ready to admit to stupidity but will acknowledge that I'm past middle age and well into frustration.
I'm in safe mode now; in regular mode my laptop has slowed to the point of only allowing my desktop to appear & I can't get anything else to work. Every time I click on something that infernal little blue donut just keeps running and running.
