LCD Monitor Loses Contact With Computer
Jan 4, 2010
1. Computer, at start up, sometimes can't find my monitor. Only way is to start the computer with the monitor switched off; then turn the monitor on at a certain time during the booting process (when I here a motherboard-beep). Occasionally the connection will be broken anyway (and I'll have to mess with the 'reset/-start button). I generally get to the motherboard page and BIOS settings. But sometimes not even that and then the only solution is to leave everything off for a while (minimum a couple of minuts – but not exactly sure).
2. Computer lose monitor when it to goes into sleep mode. This only happens if I leave it inactive for a long enough time. I can usually retrieve it if the display's gone out only for a short while, as usual - by pressing keyboard or moving mouse.
My hope is to find a solution that doesn't involve buying a new monitor.

Got a PC with Nvidia GeForce 6150 graphics card with no overclocking. Sometimes the monitor loses signal and does not work. Sometimes it works just fine. I've tried different VGA cable and different monitor, situation didn't change. I've got 4 different connectors.
- 1 VGA and DVI on Nvidia
- 1 VGA and DVI built in into motherboard.
Sometimes, when the Nvidia doesn't work, I connect to built-in card and monitor starts working. Next time when it's out, I connect back to Nvidia. There have been situations when only one of the four connectors is working. This means that on one graphics card there may be only one connector which is functioning. I don't get this. Problem isn't in the display nor the cable. It also doesn't seem to be in the graphics card as the built-in connectors aren't fully functional neither.

I turn on the computer, goes past the bios screen as normal, does the windows loading screen as normal, then the screen goes black and the "No Signal" message is displayed.
Now, here is why it is different. I type in my password and press enter, without being able to see and wait for the logon sound to play, then if I unplug monitors cable, I hear the noise of windows telling me a device has been disconnected, I plug it back in again the device connection noise then plays and low and behold, there is the desktop.
I have been running Windows 7 build 7100 for roughly about three weeks until this started happening about one week ago.
MONITOR: ViewSonic VX1932wm
GPU: Sapphire HD4850 512mb
Also, I have noticed too after logging, randomly Aero will disable itself, I have to open the 'Personalize' option and run the troubleshoot to get it to fix itself again.
I assume this is the correct section, as I am experiencing visual issues. Apologies if this is not the correct section.

When I start my computer with drivers installed my monitor loses the signal when I should be receiving a log in screen. I can boot up fine in safemode and/or if I'm using Standard VGA Graphics Adapter. To my knowledge I do not have an onboard graphics card as there is nothing to plug an avi or vga cord into aside from my graphics card. I should also mention I tried using an NVIDIA GeForce 8500 GT and experienced the same problem.

i just recently built a new gaming rig and am running an SSD for boot up.
Everything turns out just fine except when after the windows logo appears, I can hear a little crackle noise from my headphone then the monitor loses signal and my g15 keyboard LCD turns off, then a few moments later my monitor and keyboard comes back to normal and i am a the login screen. It is not a big deal but am just puzzled at why it would do this.
It does slow down my boot speed by a lot especially for an SSD. Anyone know how i can speed this up? Someone told me disable USB 3.0 to speed things up. Any problems with Asrock MOBO drivers that could affect this?

I am noticing that if the OS is unexpectedly shut down then all the state data in IE is lost. I am assuming it is cookie data. An example is Google preferences. I set it to display 100 results per page, not filter my results and open in a new window.
Every time the computer is "accidently" powered off upon reboot Google reverts to showing 10 results per page, filtered results and opening in the same page (the default settings). This goes for every site that I have remember my login name.
I am runing Windows 7 Build 7100 RC1
I am curious if anyone else is experiencing this issue.

Its been like this for a while now. That is every time i leave my computer on for over a day it loses its ability to load webpages. A simple ping to [URL] gives a timeout while any other computer on the network can still access any other website (including google.com). I suspected a failure of my computers DNS to convert DN's into IPs however a flushing and reactivating of the computers DNS cache still does not solve the issue. If i still have MSN or uTorrent running they seem to be able to connect to peers over the internet which is strangely odd, however signing in and refreshing trackers no longer work. I have tried accessing websites with the latest version of IE and FF while this problem persists.
All network settings are on automatic and i use Windows 7 SP1. I have a phone that alerts me to new mail and i have suscribed to this thread.

I have desktop that is less than 2 years old and it is having two problems: First, if I step away from the computer for a few minutes and come back to the computer, the screen is black and none of the keys will wake up the monitor. Also, I am unable to turn off the tower, even when holding down the button for 10 seconds. The only way to turn it off is to unplug the tower. When I plug it back in, I get everything back on the screen just like it was before I walked away.
The other problem is that the system clock will not keep time. This just happened a week or so ago. Whenever I manually update the sync, it resets, but won't keep time for long. From reading other posts on this forum, it seems that the CMOS battery may be an issue. Since the computer isn't that old and isn't used constantly, does that still seem reasonable? Is that normally covered under a warranty? I have never had a problem with other computers.

I have an old XP computer with all my e-mail contacts. I copied the address book to a flash drive and pasted it to my new laptop windows 7 home premium desktop that uses Live mail. When I click on it it tells me it is exporting to the contact file, but nothing shows up in my live mail contact list.

my monitor exhibited signs of flickering during start-up, but only minor ones and would just stop at the 'Welcome' screen of windows so I didn't give it much thought. Iv'e been using it with the cpu the same time I bought the monitor.But after some time, the flickering got worse. It went from 1-2 second interval flickers to a whole 10 seconds of blackness before it showed anything.Now,Iv'e got a new cpu but still using the old monitor. After a day or so, the monitor exhibited the first symptoms of my first cpu, so I just dismissed it. But after a week, It got a hell worse, before I even start-up my computer, the monitor doesn't show Analog/Digital at the top-left corner of the screen. PLUS my cpu keeps restarting after I pushed the ON button after 10 seconds or so. Is the monitor responsible for the restart and what could be the reason for the flickering?

My netbook loses its IP address after it has been asleep overnight or longer. I cannot do an ipconfig /release or ipconfig /renew. It says there is no media. My only recourse is to restart. My laptop does not have this problem.

I am rebooting "Windows 7" more than any prior version of Windows for one simple reason. When my computer comes out of a sleep mode and I click to log on to an existing session, the keyboard can no longer be used. Often when I attempt to type on the keyboard, the mouse is then lost as well.
If I instead log on and then immediately do a restart - everything is fine. So, now I have fallen into the habit of restarting every time. It takes less time for me to do that then getting something started with the mouse and then freezing the system by trying to type something. So I just accept the restart and avoid the reboot. But, essentially the restart is a reboot.
Very frustrating! Then a few times I have gone directly to the Microsoft website and they do not even mention the issue in their database. It's like no matter how many people mention the same "windows 7" "loses keyboard", Microsoft just does not care. It goes against all the other facts that say "Windows 7" is the most stable version of Windows.

I have a new Dell laptop running W7. The screen tint is far too blue and I have found the controls in the display section where I can modify the colours (and gamma etc).
I can adjust everything with no problems, but much to my annoyance, when I boot up again, all the settings have reverted back to the factory, too blue settings.
(I think that the settings even get lost if the laptop powers itself down through the various hibernate/sleeps etc; although I'm not that familiar with all of those options so am not sure.)
So, my question is how can I get W7 to remember these settings?

All of a sudden Snipping Tool is losing anything I try to save in jpeg format. It says it saves in the folder where I asked it to but nothing is there. When I redo the snip it tells me that file already exist. When I do a search the file shows up as being in as a Recent file used but nowhere else.

Whatever modem/router I use (except my old 2Wire that died in Dec. 2010), I lose connectivity after I resume/wakeup. The tray icon says "connected", but my browser (Firefox) or my email client (Thunderbird) say "no"!

Fujitsu M1450G is losing its internet connection after a few minutes of internet browsing, the wireless connection says it is still connected, but internet doesnt work. I also do a repair on the connection but it doesn't solve the problem. I have to restart the laptop each time to have internet again, and it will only last a few minutes usually. What can the problem be and how can I solve it?PS Laptop location doesn't seem to be the issue, tried it just a metre away from the router and it has the same problem. Other laptops in the house have no problem at all.

Windows 7 keeps minimizing every hour to desktop no matter what is running. I ran process explorer just before the time it should lose focus and only one program launched a minute before it does so, taskhost.exe. I tried to run with all processes killed (including explorer.exe) and that also gave good result, it didn't minimize, however I know not which of the processes does this.I first noticed the problem as screensaver quits on it's own after a while (despite the fact it has to quit on click or key press)

So. Running XP.2 (can't run XP.3; it kills Adobe's CS2 apps, which I need). Had a spare partition. Before putting Ubuntu back on it, I figured I'd install the Win7 Ultimate that'd come (unused) with another computer.
(The install was smooth enough. The updates were slower'n snail poo. But after turning almost everything back to the Windows Classic theme, it's almost bearable. Only two of my devices were unrecognized and unsupported, and they're no surprise; the tablet's nearly twenty years old (even the manufacturer doesn't support it) and the scanner's older still.)
Installed copies of my must-have software--Office 2003 (I've had to suffer through Office 2007, and will never ever ever put it on a machine I have to work on), Photoshop and InDesign CS2, Winamp .
I got my first real exposure to User Access Levels when, the first time I ran Word 2003, Win7 wouldn't let me save the new Normal.dot. I later went and copied my much-customized normal.dot from its XP location, so the file's at least there.
But: I run Word on a portrait-oriented monitor. Under XP, Word remembers the window size and position, and it's exactly where I want it, all the time. So far, every time in Win7 I've opened up an existing document, the Word window has instantly shrunk to around 40% of the size it's supposed to be.
I'm curious if this is a cling-on permissions issue with normal.dot under Win7, or a registry setting that simply hasn't gotten made (in XP, Word seemed to take care of remembering where I put and closed it by itself). Did a search, but didn't see any questions that seemed to relate to this, so I'll ask.
(I'm trying to like Windows 7, I really am. I don't much, but I'm trying. I don't mind the thought of getting a new tablet, and I've got another scanner I can use. But I really dislike having to resize my windows every time I open a document--I spend 75% of my time on the PC in Word, just writing.)
And again, I hate, loathe and despise Office 2007 and 2010. I do most emphatically not like the "death by honey and marshmallows" interface that microsoft seems to think is so great.

I have an Asus G50vt-x5 laptop (with windows 7 now, originally had vista), and my old battery was losing charge so quickly. So, i got a new one. I did everything you were supposed to, charged it up, discharged it, charged it again, etc.For some reason, i can just be playing or doing things on my laptop, and it'll randomly just lose ALL power. For example, i was playing a video game the other day and was at roughly 65% battery, and suddenly the computer just instantly died. And i don't know if any of you have seen an asus, but there is a little light on the panel with the power button for like a "quick start", and that light is ALWAYS on. but when the laptop died it wasn't. Which i take it means absolutely no power was going to the laptop.

I don't know if this is a harware issue with my SSD, disk controller (motherboard), power supply or something else, but depending on what I'm doing, the computer will operate for a few minutes then freeze and eventually reboot itself. When it reboots, I get the "Bootmgr is Missing" message until I cycle power a couple of times. I've tried booting from the Windows 7 repair disk and typing "bootrec /fixboot", but the problem eventually returns.I can't get a full image update from Acronis because it hangs in the middle of the image, even if I say to ignore bad sectors. If I run the HDTune diagnostic on the SSD, it seems to always stop after about 3 minutes and always in the same spot, at 15,432MB. Is this a problem with the SSD or the disk controller?

O/S: OS Microsoft Windows 7 Ultimate (6.1.7601 Service Pack 1 Build 7601)

i have a acer aspire running windows 7 with 500gb hdd and 4 gigs of ram on board graphics card. The computer turns on everything initiates like normal but the monitor wont turn on, im not getting any signal. There are no beep codes etc, also ive tried removing the little lithium battery to reset the bios and still nothing. Ive tried using a different monitor and its saying no signal. I have another computer which is having the same problem its a acer something 1 gig of ram 250 hdd and a readeon graphics card...cant remember the exact name. With this computer i was attempting to add more ram to the extra ram slots and the computer booted up and worked but i only had 2.50 gigs of ram rather than 5? So i turned it off and repositioned theram.which now i wished i hadnt, i now get no signal from either of the computers.

I just finished a new machine, EVGA VIDIA GeForce 9800 GTX+ card. The card has two DVI outlets - 1 S Video outlet. I'm using a Sony Bravia 32" XBR for a monitor.
Using a DVI to HDMI adapter gives me a not so good picture.
Using a DVI to VGA adapter and connecting to the TV in the "PC IN" area, give me a better picture, but still nothing all that great.
Using my Dell laptop, with NVIDIA GeForce 9400M G video and an HDMI outlet gives me a great picture when I go HDMI to HDMI.
I know I am not happy with what I have, I don't know what to do next.
My 1st thought, based on the laptop experience, is to get a video card with an HDMI outlet.
My 2nd thought is to try the S Video connection, which I would if I had a cable.
My 3rd thought was to come here and ask advice from people who probably can come up with more than 3 thoughts at a time.

I've searched the internet far and wide as well as these forums and have not been able to find the answer. Unfortunately, my sister-in-law's dog killed my 2nd monitor so I haven't been able to test on my own since installing the RC version last week. (new monitor will arrive next week)
My question:
If you RDP in Windows 7 from a computer with dual monitors to an XP computer with dual monitors is the multimon support available?
I want the session to feel as though I'm at work with dual monitors.... not just spanning the 2 monitors. My work computer runs windows xp.
Currently the only way to get this functionality in xp is to use the span command and to use add-in 3rd part software that does not work that great.

My monitor starts OK but in a few minutes the screen is either covered by a fine mesh multi colored grid or 4 verticle bars approx. 1-1/2" wide made up of fine multi colored lines similar to those seen when I defrag but running top to bottom of the screen.

Sometimes when I click start and sleep on my computer (windows 7) the monitor will go to sleep but the computer is still running. I cannot wake my monitor up so there is nothing I can do to wake it up besides manually turning it off using the button on the computer case.
