I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

All right I can usually figure out what's is with my laptop though forms and doing my own research, however this one has me stumped.

Sony VAIO VGN AR230G Laptop, Windows XP Media Center home edition, SP2
about 15 months old

The screen will stay up for hours if I leave it at the log on / Welcome screen. If I type in my password the OS comes up and the Apps start coming on about 1 - 2min after most things are up the screen will flicker black. If I move the touch pad during the flickering I can see a gray box as the icon where my mouse pointer should be. The desktop comes back for about .5 seconds then diappers. It does this for 10 - 20 seconds then goes completely black however the hard drive is still running. Every once in a while it will stay up long enough for me to type this thread. NOTE: I suspect the apoint.exe file that applies to the touchpad. When I move my figures back and forth over the touch pad I can delay or overcome this whole process however it is spotty at best.

What I'v done so far:
-Checked for driver updates -System Restore -Check Disk -Run several scans with Symantec and Spy Bot S&D -searched the forms -HijackThis

Answer:Monitor Flickering Then Goes Black Only After Log On

First try and update your computer especially your touchpad software and even your DisplaIy Adaptor driver also try if it is possiable to disable your touchpad in the Cmos settings and using a USB mouse just to try and see if that makes any diffrence.

Hello everyone.

So there's something wrong with my monitor. Every few minutes it goes black and the screen returns after a few seconds. However when it comes back it looks like the resolution has been changed and then changed back. For example my browser window isn't fullscreen but windowed and windows like Skype get moved around. Sometimes it says there is no video output but everything is plugged in the way it should be. Any fix to this? Here's a picture of what my windows look like when the screen reappears. Any help would be appreciated.

I have this problem too now. (connecting to DELL U2715H) The weird thing is it didn't for the first six months I owned it.  And doesn't happen with built in screen. 
 
To make it even more annoying this started happening about the same day my premium support ended. 
 
I'm not impressed. 
 
UPDATE: A hard reset stops the black screen. Instead I now get this unhelpful messagebox popping up at random..

Since I started using S2716DG,  I have been getting random freezes and black screens. Freezes seem to be trolling me at random times, but when it comes to black screen flickering they sometimes happen when initiating a game or exiting it, although more often pretty randomly as well. Flickers usually happen, in one case, 2 times, taking about 3/4 of a second each. I mean I don't really expect much help on this cool monitor, but are these things common? Should I continue to expect this?

Hiya Everyone... sorry to bother you with this problem, but it has stumped My Friends and I already >_<.

Currently, my monitor has lines about 15 pixels long and 1 pixel wide that flicker across the entire screen. If I turn up the Gamma and Brightness.. they sometimes go away. The light colors, like the light blue or white on this site, have very few lines, while the dark colors, such as my gray and black theme in windows xp, they nearly cover the entire space. (just for an example, in 1600x1200, the window under the URL bar in internet explorer has around 100-200 lines flickering at a time, while the gray space above it has around 300-400 and the task bar has around 200-300)

Now for the trouble shooting. I have tried the monitor on 4 computers total (2 desktops, 2 laptops) and the flickering is there on every computer (yes, it also is flickering during the bios boot up, and when the OSD is on). I have tried 4 different video cards on this computer also, (GF2 mx200, GF4 mx440, GF fx5900, and GF fx5900u) and the lines are on every card, so i am pretty sure its the monitor thats the problem ^^. I have tried to see if it is maybe some sort of interference from magnets or the sort, (i turned on and off moire protection, moved the speakers and sub-woofer, connected to a different power circuit, as well as moved my computer about 7-8 feet away) but it doesn't look like that is the problem either. I have replaced the power cord, as well as moved the 15 pin cable around,... Read more

Answer:Monitor Problem-> Black Lines Flickering

Yup, your problem probably breaks down into two possible general sources.

First action degauss the monitor. Wait 30 minutes, degauss again. Also give a couple good smacks on the side and top with your hand. If the cause is bad solder joints or loose connectors usually will see an effect.

First reason:

1. Something external, probably noise from some source being impressed on the AC power and affecting the video. Can be a huge number of things, doesn't even have to be in your apartment. Things like the power wiring itself, appliances, lights, stray RF, can be a huge list, including the cat in high voltage mode, nearby radio transmitters, etc. etc.

First test:

Take the monitor to somebody else's house totally away from your location and hook up and see if the problem follows. This test should determine if it is in the environment or in the monitor. The more remote from your location the better, hopefully a house with no known problems.

Second reason:

2. If problem follows after test one, the problem is internal to the monitor and basically if under warranty they would owe you a new monitor. Can be a bunch of causes, more than likely more related to cheap manufacturer. The monitor can generate interference within itself, similar to "hum bars", could be flyback, retrace, CRT itself, power supply related. You may be able to adjust it away for a while but smart move is to demand another.

If moving the monitor to another location clears up the problem the... Read more

Hey guys, usually pretty self sufficient when it comes to hardware issues but i have no experience with monitors going awry and seek some advice.

The issues a relatively simple one, when first starting the computer there is a problem with the monitor getting power, the power light stays off and the screen, completely black flickers making a clicking noise gaining a very slight gain in brightness all the while the power light staying off.

After unplugging from the power, and disconnecting the vga connection a couple of times eventually the power light comes on and the screen works.

During use there are no issues with the picture and it works fine, it is only when the computer has been shut down and the screen off for a period of time i have this issue getting it back on.

Any help as to what it is appreciated i suspect it has come to the end of it's life as it is almost 3 years old now.

The monitor in question is a GNR, showing as a plug and play on devices and running of a gforce 8500 gt.

Thanks in advance

I connected my DELL 4k monitor using my new USB-C dock (Lenovo) + Displayport cable. As soon as I plug in the cable, the laptop screen starts flickering terribly but the external monitor stays black. After a few seconds, it sleeps; the laptop keeps flickering (screen image/black/screen image/black/...). What can I do? I did not change any display settings. Simply unpacked the docking station and connected the monitor. It does not even give me a chance to change any display settings because as soon as it starts flickering, it becomes almost unresponsive.

I purchased a new Z27s monitor on Amazon 9 months ago.  One week ago, after a scan with Avast, the lower half of the screen started flickering and I have horozontal black lines across the entire display.  It clears up for a few minutes once in a while but overall, it's a banded, flickering mess.  I've used Avast since I purchased the monitor so I don't think it would suddenly cause problems, but I could be wrong. I've tried pluging it directly in the wall instead of a strip, using an outlet that's not on the same breaker, removing all phones, turning off nearby networking/wifi devices, hooking it up to a different computer to make sure it wasn't my GPU, using a different hdmi cable and using different hdmi ports.  Nothing helps.  Does anyone know what the problem might be?Also, when I checked out the HP warranty,  I found the product number is not associated with the serial number.  I'm wondering if that means I have counterfeit equipment.

This has never happened before. I went on vacation last week and figured i would turn my computer off to save power. So i did. When i came back and turned on my computer after a week, i saw these slanted black bars with little stripes of the screen through them, they were flickering very fast. I got to the setup screen where all the information for the computer is at (Bios, Ram, CPU speed, etc.) and it stopped. I go back into windows and it started again right when i get to the windows loading screen with the blue bar and windows icon. After about 5 to 10 minutes it wears off for some reason but every time i turn my monitor off, or it goes to power save mode and i turn it back on, they are there again for another 5 minutes. What is this and how can i fix it?

by the way, these stripes re appear when i go into certain games or a website with a dark backround, they dont show up with Call of Duty 4 but they do with Overlord. In Overlord they will go away when i look up at a bright sky but re appear when i go into a dark area... its so annoying, i cant play with them there...

Me and 2 co-workers got new computers, E7250.
Together with the E-Port Plus II docking station. (PR02X)
Problem is that one of the external monitors keeps flickering to black, as if loss of signal after a while.
Docking out and in again solves it, or removing the DVI-cable and putting it in again.I run 3 external monitors + internal.
Co-workers runs 3 external only.Same on all, one of the external monitors flickers.I have the latest BIOS, latest driver for GPU and Chipset.This does not help.Any suggestions?

In the last few months I have purchased the ProBook 655, UltraSlim Docking Station, and two monitors all from HP.com.  I am trying to connect the monitors from the Docking station's DisplayPort to the Monitors VGA port.  The screen flicker, shake, and go black then come back on again.  I have updated the graphics card. Updated the firmware for the Docking Station with several different updates (SP69276.exe, SP74203.exe, and SP75855.exe). All this resulted in absolutely no change. Also, tried 4 different cables.  If I undock the computer and use the displayport on the side of the computer the monitors work perfectly.  So I don't think that it has to do with the graphics card.  The VGA to VGA cable between the docking station and monitor works great too.  But I really desire to run to full size monitors and there is only one VGA port on the docking station. Does anyone have any suggestions on what to try next?  I am finding it impossible to even find a phone number to call HP to see if they can help.

Hi, I have a brand new T460s, was very excited about it. It arrived about a week ago, it was imported from Germany as they don't yet sell it here in Hungary. However there is a major problem with the display:Whenever the display is (re)initialized (for example during boot, resolution change, sleeping screen wakes up etc) random pixels start to flicker/flash in random colors and the display keeps switching off and on every couple of seconds for a duration of anywhere between 10-120 seconds. After a while the number of pixels flickering reduces and the monitor switching on-and-off stops (so the screen becomes usable), but the flickering never really goes away. The flickering at this point is barely noticeble unless one pays special attention to it. I run a linux distro which added official skylake support only recently in the 4.4 kernel, and initially I thought the problem is related to a bad driver, but now I'm 99% sure it's a hardware problem. The reason being is that an initial flickering/monitor off-on switch happens the second the laptop is turned on (during the display of the Lenovo logo, this is even before the UEFI is in control). Furthermore there are no indications that any software component is malfunctioning (no errors, switching off e.g. hardware acceleration/fiddling around with driver settings has no effect). I have warranty on the laptop but it woul...

I have HP Desktop Tower Pavilion with windows 10, I had two HP S2031 monitors in dual mode, worked fine. One of them died, I got a good deal on a larger HP 27er monitor.  I hooked it up, they were both working fine ... it was using a default monitor
setting ... and then yesterday the computer downloaded some updates, and in doing so, it downloaded the driver for the HP 27er and installed.  The next thing that happens is the older HP S2031 starts to go dark ... like it is going into sleep mode, and
then it is totally black.  On reboot, it starts up with both monitors working, but within seconds of reboot the HP S2031 goes black again. The HP S2031's buttons do nothing, other than the power button, which turns it off and on, but that is it.  
I have done all troubleshooting, I did not even have them set up to sleep, all settings are at NEVER.  In coming here, I have done all the fixes I can find for similar  that are posted for similar issues, the Windows Key + W... nothing. 
The create new power plan ... nothing.  the device manger>display adapters>disable then enable ... nothing.  and lastly Start>Control Panel>System>Device Manager>display adapter>driver tap>update ... still nothing.  HOW
DO I GET THE HP S2031 MONITOR TO NOT BE IN SLEEP AND HAVE BLACK SCREEN.  I can not figure this out and am not finding any fix.

Hi, all, I have a Dell XPS 15 laptop and recently bought a Asus MB169B external USB monitor.  When I plug the monitor in, the laptop monitor (not the external monitor) flickers about every half second.  If I unplug it, it stops.  I upgraded my video driver to no avail.
Is it simply a power supply issue (the external monitor  does not have a power cord)?  Anything I can do?  It does it even if I have the laptop plugged in and charging.  
*something interesting - I just discovered if I duplicate the display and not extend the flickering goes away...but that kind of defeats the point of a dual monitor for me.

I have a strange problem that seems to happen completely at random.

My PC freezes (sort of) so that even though I can still move the mouse arrow around the screen I am unable to click on anything. The monitor then goes totally black for a few seconds before everything returns to normal.

There seems to be no pattern to this, it can happen within minutes of turning on the PC or may happen hours later. It can happen very frequently (several times within a few minutes) or go hours without incident.

I dont know where to start as my attempts to Google similar symptoms didnt really work. The PC is fairly old (about 6 years) and is on its second PSU and second monitor but both have worked fine for some time.

I have an AMD 2600+ 1.9ghz with 512mb RAM XP SP3
I dont use it for anything other than browsing and simple Excel, no gaming or downloading etc.
Other than this the PC runs fine (though it takes an age to boot up) and I am fairly sure it is free from viruses.

If this problem sounds familiar to any of you any help would be gratefully appreciated

Thanks.
 

Answer:Random freeze and monitor goes black

if the monitor goes blank how do you know it is also freezing?
try go to control panel power options alter turn off monitor to "never".....alter anything else to suit! and you can do it if the power options did'nt work then

... tap "F8" key @ boot-up select "safe mode" using arrow keys [press ENTER]

... once in safe mode click "no" on the "pop-up" that should guide you to system restore

... select a restore point by altering the restore calendar to a time when the pc was working fine.

Hi there, I have been using these forums as aid to me for a while now and they are so incredibly helpful at crunch time. I want to thank all who help out here.
My problem, The monitor goes black every few hours. The light on the monitor goes amber color so that leads me to believe that it's the graphics card that stops responding. I also don't rule out that one of my HDD's are going bad as well. Maybe even the CPU. However, the Pc still runs and all because I can hear the fans.

It has been doing this off and on for the past year now. It would come and go so I didn't get to worked up about it. Now it's happening a few times a day. There is no pattern to it b/c I leave it running over night or when i'm playing games it does not matter, it still goes out.

I dusted my pc to see if that helped, maybe it was overheating, no help tho. Sometimes(maybe 15-20% of the time) it would even reboot itself after the monitor goes black. Can someone help?

My specs

Answer:Solved: Monitor goes black at random, hdd? graphics?

Well you can rule out the hard drive. But that leaves the monitor, video card, power supply, RAM, motherboard, and overheating.

Check all the fans; there should be one in the power supply, one on the video card, and one on the CPU. There may also be a few more. Make sure all are spinning at a good rate.

You can also use something like Speedfan in Windows to monitor the temps and voltages of the system: http://www.almico.com/speedfan.php
Post the temps and voltages.

Also, I believe your Radeon 9700 requires a seperate power connector from the power supply. Check to see if your card has the 4 pin power connector and if so that theres a power connector plugged in.

Another thing you can do is pull out and reseat all the cards and cables to make sure there's good contact.

I would also suggest you test the memory: http://oca.microsoft.com/en/windiag.asp

Hi, I have windows home 7, home built pc with Asus motherboard. Don't ask me further spec details cuz I have no idea about most of the specs (an ex built it and can't get in control panel due to monitor issue). I just know that it's supposed to be kick-*** with a 5.8 windows score.

The PC boots fine, gives you the option to start windows normally or leave it do its' thing... but either way I try, it makes no difference to monitor.
When it boots, the monitor shows all the usual details, the bios pic, starting... and as soon as it reaches desktop point (I think), it goes black even though monitor is still powered and no errors about no signal. If I turn monitor off and on, it will quickly show me the desktop then it goes black again.

I'd appreciate any help or insight.

Hi, first thing I would try is to connect the PC to another monitor that is known to be in good working order. If the same problem occurs then we will know it is a problem with the PC, if it functions normally you will know it is a problem with your monitor.

(befor the update it worked fine I had no issues). I only used external monitor occasionally so I decided to wait for nvidia to fix the problem (rolling back to previous nvidia driver version did not help). Well now after 3 new version the problem persists. I tried using  the hot key on my keyboard to change between 4 different monitor-laptop setups (only laptop, only monitor, resize..) and it did not help.  I tried recording my laptop screen when I pluged in the external monitor and the video is normal (it isn't black). I then opend nvidia control panel to see if it recognises external monitor and recorded the screen. My external monitor (samsung) was recognised.Click for video on youtubeIn between black flashes i pluged in/out the external monitor.Translation for "zaslon na prenosniku" : laptop's screen. So any idea how to resolve this problem ? Thanks in advance.

I need some help. I have acomputer monitor that is roughly 10 years old. THe monitor last night decided to suddenly turn off and the power button started blinking. I unplugged the power to the monitor and let it sit overnight. This morning I went and plugged the power back into the monitor and pressed the power button on it. When I pressed the power button the button started blinking again. I have never had a monitor die like this and I would like to know why it died and if it can be fixed. Some more info is that i had only been on the computer for less than 2 hours. I have not spilled anything on the computer, the vent is completely uncovered, and the computer is in good working conditions according to the mannual. I need to know asap please. The tower still works perfectly fine it is only the monitor.
 

Answer:Monitor is black and the power button on the monitor is blinking

If you could try the monitor on another PC, that would confirm the monitor is faulty. In any case if the monitor is bad and considering its age, it would be best to just replace it. It would not be worth fixing.

I have been running a dual monitor setup for several years without issue. I was using a 28" Hanns G 16:10 1920x1200 via HDMI & an ASUS 27" via DVI. They were connected to a Zotac GTX 570 and then later to a Gigabyte GTX 770 4GB graphics card.

About a month ago I substituted a 30 Inch Monoprice 16:10 2560x 1600 monitor connected via DVI for the Asus monitor (both MP & HG still connected to GTX 770). In the last two days, the Monoprice monitor has gone black twice. When this happens, all programs that were visible on the now black monitor combine with the programs on the visible monitor. When I open up the control panel, it only lists the Hanns G (still visible) monitor as detected and the Monoprice (black) monitor has to be re-detected. After clicking on "Detect" the monitor returns to normal. This happened once while gaming (Left 4 Dead 2) and once when I wasn't gaming...can't remember exactly what programs were open at that time.

I updated my graphics driver between the time it first happened and the second time it happened. I also used device manager to see if there was an available monitor driver update available, but windows claims that the most current driver is installed and that the graphics card and both monitors are working properly.

I would really appreciate any assistance that can be offered. The 30 inch monitor wasn't cheap and I am hoping that the monitor is not the issue. I have not yet done any trial and error measures such as ... Read more

I am working on my sister-in-law's laptop attempting to connect a 2nd monitor.  I have just replaced her RAM to 8 GIG (factory was 4 GIG)  and thought it would be easy to just hook up this second monitor.  We purchased a DVI to HDMI cable, hook the cable up to the monitor. Make sure there was power to the monitor.  Then I change the display settings to mirror the displays.  The second monitor turns on and shows the display however it in a split second turns black.  Power is still on for the 2nd display however it just displays black.    The graphic card I have in the HP-15 touch screen is the amd radeon (tm) r4 graphics.  I am wondering if I turn off the touch screen ability would it work or if anyone has any tips to get this second display to work please let me know.

For a while now I have a small problem with my desktop and it is starting to annoy me. The following things happen:
-When I start my computer and monitor then the monitor works for about 10 seconds before it turns black. Usually this is just after logging in, but if I don't log in fast it turns black at the login screen. It stays black for a minute and then everything is back to normal.
-Sometimes the monitor thinks it has no video imput in this minute and I have to restart the monitor or computer.
-When my computer has been on a while and I decide its time for a little break I turn off my monitor. When I turn it back on again after 30 minutes the same thing happens.

Does anyone know what the problem might be? It feels like a waste to have a computer that can start up in under 10 seconds and then have to wait for a minute before the monitor works properly.

Hi all.

So, I just got a spiffy new monitor from Woot.com (a debranded HP w2338h). Gorgeous, works great when it's all by its lonesome. Not even a dead pixel!

However, when I try to hook it up at the same time as my old HP vs17 (which also works great by itself), it goes black, says "no input signal," and goes to sleep. I'm using a Radeon 4670 HD. Brand new drivers, Hydravision installed. Windows 7 64-bit.

Catalyst detects both the monitors, offering an extended desktop, and when I move my mouse off the side of the vs17, it disappears and takes time to return, indicating that the computer thinks the screen is still on and is moving the mouse all over this expanse of screen real estate.

Also, when I boot up, both monitors show the boot-up screen just fine, up through the Windows logo load.

Tried switching the cables on the video card, no luck.

Any ideas?

I was working on my computer when the monitor suddenly went black. Nothing seemed to be different in the tower; there were no sound changes, no light changes. The monitor's power light stayed on. I recently acquired another computer and monitor from a friend and decided to hook both monitors to both towers to troubleshoot. Both monitors work fine when hooked up to the second computer, and both monitors stay blank when connected to the first computer.

So, the problem has to be in the tower. Based on the information I've given, what sort of problem does it sound like I have? What should my next step be?

The only spec I have for the machine, since I can't access the hard drive, is that it's running XP.

Answer:Monitor went black. Monitor itself isn't the problem.

Welcome to Tech Forums, subway42!

Sounds like it could be the graphic card in the first computer not giving a video signal. See if you can acquire another graphic card for the first computer.

I've suddenly gotten this problem: Return to my pc after a while and find that the monitor has gone black and pressing the power button gives the message "No signal". Moving the mouse or pressing buttons don't result in a wake-up. The hard disk lamp is blinking so it seems it's working (in this case video capture).
I have turned off the screen saver and I don't use put computer/HD to sleep.
Anyone having a clue?

Answer:No signal to monitor - monitor has gone black

I would probably say that there's a part that's burned out inside it. It's a specific part that I don't actually remember the name of. Don't know how long you've had it but I know that it happened to one of my Hannspree monitors. If I were you I'd Google the make of your monitor going black because it's not technically a Windows issue. As soon as I did a little research I determined that I could send it to the manufacturer to be repaired luckily it only initially cost me $50 and I made a mistake sending it Fed Ex.
**Actually. Can you get the menu up for the monitor pressing the menu button on the monitor itself? If not there's a problem in the monitor like I mentioned.
Having two monitors obviously is great because you'll know it's not the graphics card.

Hey!

A few months ago I noticed my monitor began to flicker on and off every once-in-a-while.
As time went by, it got worse (the flicks would be more constant, and sometimes last for longer).
I figure it'd be my monitor (it was 6 years old), so today I finally went out and bought a new one "ViewSonic VA1912w" 19" LCD screen.
I install it, with no problems, up-to-date drivers and all that, and now the monitor flickers for a longer period of time; Like, the screen will flick black for 3-5 seconds at a time..

My computer model is "Q-Tech".
I am using XP Pro, Version 2002, Service Pack 2.
I have 2.41GHZ, with 256MB of RAM.

Does anyone have any suggestions, please?
If you need more information, I will try to provide it; I am so desperate to sort this out - I thought today would be the end of my problems, but it appears just to be worse :(.

Thank you for your time. J.

Hi allHave a crt monitor which my other half has noticed its started to devolpe a rather annoying / worrying flicker(over the last week).Have checked the basics ie screen rez which is set to 1024x728 and refresh rates which is set to 75hz. Am running xp home and have the hide modes that this monitor can't support ticked so am not running it at anything it can't handle.Graphics card is onboard and am not at home at the mo so can't say what its is specifically just know its an intel model. Have checked in device manager thou and everything looks fine from that end.So then my question is this am I missing something basic or is it a sign that the monitor is on the way out its only just over a year old thou and not anything special as it was bundled in.Any ideas thoughts suggestions?Cheers

Question: Monitor Flickering

I have a unbranded 15" flat screen monitor which when my p.c is not being used will start to flicker on and off at various frequencies.
I haven't had this happen when I am actually using my p.c now for example. But if I was to leave it for an hour or so sometime less it will be flickering when I come back to it.
I can still run the p.c but obviously not being able to see very well so it doesn't actually crash. Sometimes if I'm lucky it will cure itself quickly.
Mostly it needs a restart and when it boots up to my desktop it will quite often still be flickering.
At the first screen after a restart I can get into the bios and the screen will be ok it seems it is only whilst the xp pro is running that it cause the fault.
Finally the other factor which may or not be linked is when I shut down \ restart the monitor displays no sync and always has done it didn't seem to cause any problems because at first everything worked ok.

Please any advise would be grateful

Ok, I'm having this problem with an old crt monitor. I know the monitor works, so that's not the problem. It's an old NEC Multisync FE1250 and when I plug it into the VGA port on the side of my computer, all the screen does is flicker. I searched around on google and every thing I found said change the refresh rate. I tried every rate there was 59, 60, 70, 73, 75, and 80, but none of them got rid of the flickering. The flickering is so bad that you can't see anything going on. I've also had this problem with a LED tv that my aunt had.

Question: Monitor Flickering

This is a particularly strange issue. My LCD monitor has begun a strange staticky flickering, where bars of static flicker across the width of the screen (vertically extremely narrow, though) whenever a certain color or something is on the screen, wherever the color is present and all along that span of width. I suspect it is a shade of blue that is doing it- this background on a webcomic reliably causes it when displayed, but the individual background tile doesn't seem to. The effect is very sporadic normally, but having that webcomic maximized, as an example, causes a significant amount of static after a minute or so. I have not yet noticed the problem in games, but then I haven't been paying attention in them.

Has anyone any suggestions please.

Check what refresh rates the moitor is able to support and set it to the highest possible. You should be able to get the information from the documentation or HP's site.The default setting is 60 Hz because all TFT monitors will run at that, not because it is the best refresh rate.

Answer:Monitor flickering?

flicker on and off? Well, if it doesn't do it any other time I say forget about it. If it's a new problem, or it happens randomly when booted, I would guess the monitors failing, that or theres a prob. with you video card. If it doesn't do it after windows boots and or it's been doing it as long as you have had your computer, it's probably some power quirk with the comp or video card and I wouldn't worry about it.

Answer:flickering monitor

Good spec system, good video card, but did you figure you were saving money on keeping an old 15" monitor? You have put a hobble on your graphics card, because you are limited by your monitor. Depending on what resolution you are running, I'll bet the refresh rate is below 70, which is why you will get flickers. I checked the Spec sheet out for the p50, and it states that max res is 1280 X 1024 at 60 MHZ refresh rate. That will produce a flicker. If you keep your settings to 800 X 600, you might get a refresh rate above 72, which will eliminate flicker. If you are going to be playing games, then I would recommend a newer monitor. Monitor technology has changed as well, and while it makes very little difference when viewing spreadsheets, while playing games you want the best possible.

Hi,I have a Mitsubishi Diamond Pro 930 monitor which is just over 2 years old. The screen has started bouncing and sometimes goes completely black with a white line through the middle.Sometimes it will be fine for days and then one day will start playing up. It might go a few days with no problems before it starts again.A hard bang on the side of the monitor seems to put things right. Does anybody know whats wrong and whether it is worth repairing.Thanks

Answer:Monitor flickering

What's wrong is a faulty component, or more likely a bad solder joint, in the monitor.It may be worth repairing - you will have to get a quote from a monitor repairer.If it's only 2 years old, it may still be under warranty - most monitor manufacturers warranty their products for 3 years - many warranties are on-site too.I suggest you look out the original documentation, as it will probably tell you the length of warranty, and arragements (where to call, etc).

Question: Monitor Flickering

After recently upgrading my video card to a GeForce6800GT (Overclocked ala BFG) I have started to notice odd flickering problems when any substantial load is put on the card.

The screen runs fine except for random pixels on the screen flickering, but occasionally the entire image will disappear, as if you unplugged the input cable from the screen for a second. It happens enough to be incredibly annoying and is causing some pretty bad eye strain.

I'm thinking that the cause may be due to a lack of power being supplied from the PSU, as it is rated 305W whereas the card is listed as requiring 350 (I know, it's an old prebuilt Dell.) and I'm working on getting a new one. I just wanted some input on other things that could potentially be causing this before plopping down the cash for a new one.
 

Answer:Monitor Flickering

As you are outside the recommended PSU ratings already, remember that they will be severely exceeded again with overclocking the card, Power use rises faster than the overclock ratio, as does the heat.

Things to check

is it plugged in securely to the vid plug on the back of computer

do you have the latest drivers

are the settings correct - one would guess that the factory settings would be correct for the monitor that it came with.

Since it works fine with the old computer, my guess is that it is going to be a minor problem and you should be able to solve it. Do you have a monitor to hook up to the new computer to see if it does it with another monitor. A setting of 75 should be fine if the card supports that refresh rate. You could always lower it to 60 which is a minimal rate to double check it...doc

Well , to start it wouldn't hurt to update to at least SP2 and upgrade your ram a bit. Check all connections, and reseat your video card, update your drivers.

Question: flickering monitor

First, I'm sorry If I have posted this in the wrong place

My monitor has recently started flickering. I installed 2 new games recently (C.S.I, and Mall tycoon) I have had no problems with the C.S.I game, however the mall tycoon game, after playing it for a couple hours shut down with a macromedia error, (the screen goes black and it takes a bit for windows to come back, then I get the macromedia error report thingy)
last night when I played it, after it shut itself down I noticed I had a yellow triangle with a "!" on it and it said something about virtual memory being low. I have this game installed in my program files...should it be somewhere else?(the program file shows it is 160.00 mb)
the total size of my hard drive is 38.3gb free space is 22.9gb
I have 256mb ram(I think )
 

Answer:flickering monitor

Sounds like the video card could be overheating.

Question: monitor flickering

I had this heavy flickering in my screen,specialy when the back-ground was dark.Than thanks to the people of the forum I fixed it. The problem was the refresh rate wich was put at a lower state.When I switched to the higher one I noticed that there were only two choices : 60 Hertz and 75 Hertz (what I put). My question is: Is there any higher point i can choose for my SAMSUNG SYNCMASTER 940 BW?

Answer:monitor flickering

Hi Maxtrimi,

Usually at 75 Hertz, the flickering will stop. If a higher refresh rate is available, you may have to increase the resolution to see it as an available option.

For more details, see:

Hope this helps you,

Question: Monitor flickering

I'm not sure if this is software or hardware issue but I had this problem for a long time. Also maybe the title should be screen flickering instead of monitor flickering.

My PCs are always on, 24/7. This last one bought not 6 months ago(monitor is older) has a very weird issue:

1.So, my PC is never turned off, when I'm not using it I just turn off the monitor. So, when I turn the monitor on again and do some action(open a browser, open a new link in the browser) the screen starts rapidly flickering(from black to normal).
Sometimes I can halt this flickering by clicking on the normal part(click on any normal part of the screen). But most of the times I have to hard reset. Or if I' am fast enough reset via ctrl+alt+del and use task manager. Of course I have to hard reset because I can't see anything due to black screen, not because computer is frozen or something.

2.If I turn on the monitor and wait for a few minutes without doing any action whatsoever(just stare at the desktop) flickering will not occur.

3.Flickering never occurs while the monitor runs after initially being turned on, no matter how long it stays turned on.

4.This could be a false correlation but I noticed that if my air conditioning unit(which is positioned right above the monitor) has run for a while and then I turn the monitor on it has a much greater chance off flickering.

5.If I open a new tab in internet browser(firefox) with a middle mouse button the chance of flickering occurr... Read more

Answer:Monitor flickering

Rather than turning the monitor power switch off, I suggest you use Power Options to turn it off after a selectable time delay of no activity. A simple movement of the mouse or any key on the keyboard turns it back on.

I don't know this will make a difference, but its worth a try. See the screen shot

Question: Monitor flickering

Today my monitor just starting this little flickering thing, the picutre never goes out but there are little lines of distortion (I dont mean black and white fuzz, but like the picture just being slightly distorted) jumping around on screen for a few seconds at a time. THen it pauses for 3 seconds then does it over again. Could this mean my new 19" monitor is a P.O.S. (I just bought it about 6 months ago after my old 19" monitor gave out after 6 months, and no it's not the same brand or kind as the old one).

One other thing I've noticed is that if I turn the volume all the way up I can hear little static "pops" that coordinate to each of the flickerings, I was just wondering if that could mean it's not the monitor since it seems like if the monitor was giving out the speakers wouldn't be making any noise to the flickerings. So maybe it might be a video card problem? Any advice/tips/suggestions would be great before I take it into a shop and just let them figure it out. Thanks, hopefully.
 

Answer:Monitor flickering

First check that the cable from the video card to the monitor and the monitor power plug are securely connected. If all that is good, open up the case, and reseat the video card. While inside, make sure other cables are inserted correctly. It sounds like a loose connection someplace.

Don't know if anyone can help but I have a 10 month old advent pc and am using an LG Flatron monitor. Problem is I am getting a flickering across the screen which is driving me mad. LG have been brilliant, sent me out two replacement monitors but after checking on PC at work the monitor is NOT AT FAULT. PC world have sent engineer out to fit two new graphics cards and now a new motherboard but the screen is still flickering! Have downloaded latest drivers for both graphics card and monitor but still flickering. Doesn't do it all the time but when it does decide to do it it is distracting. Keep getting a blueish tinge to the display, which reverts back to normal for a second or two and then kicks in again. Touching the side of the monitor helps for a while but problem soons starts again. Same monitor connected to work PC can be picked up and moved around with no flickering!! Please help!!!!!

Have you tried moving the comp to a different room? If it works ok at work, then there could be something near to where your monitor normally is that`s causing interference.

Question: Monitor flickering

My monitor every so often flickers and was looking like it was fixed earlier when i tried to uninstall the driver and removed the video card and other things like that. I put it all back together and it seemed to work. but it has started happening again. Changing the refresh rate hasnt helped. I have a radeon 9800 pro and a syncmaster 914v. thanks.
 

Answer:Monitor flickering

LCD monitors aren't supposed to flicker... What kind of 'flickering' are we talking, can you describe it? Possible causes are the display driver, in which case it is normal if it only happens during system startup or when exiting 3D applications. Another cause can be a broken backlight, which is bad.

Hello,

Thought I would ask the experts..... Every now and then my computer monitor will flicker. It goes completely black and then in a few seconds it will return to normal. I have been told it could be a virus or a computer hacker getting into the system. I do not know if that is true, or just an urban myth. I have however ran system scans for viruses and they have returned clean. The problem is finding a reliable competent virus scan. I currently use Microsofts LiveOne care because Microsoft offers it, and I figured they would know more about Windows XP etc. I use crapcleaner to remove unwanted files, and use to use CA (computer associates i think) virus scanner before the microsoft virus scanner. I sit behind the secured wireless router from ATT so I think I am somewhat secure.

Let me know if there is any truth to the screen flickering and what I should do.

Thank you.
 

Answer:Regarding Monitor and Flickering

I think it may be hardware either:
The monitor itself, is slowly dying
The data or power cable is not seated correctly
Or the video card that you are connecting to is not seated correctly, or faulty

To remove all other possibilities:
Download the current Video Driver for your computer, from the manufactures site.

Question: Monitor Flickering

Hi i am back with another problem. This time around its my monitor. Its been behaving erratically for a while but it just got worse. Earlier it used to flicker as if there is a current flickering problem but that is apparently not the case. While flickering a few black lines start dancing accross the screen and the screen size starts reducing and becoming normal.
Now in addition to the above after flickering a few times the screen goes blank reducing to a single blue line in the center of the screen. I tried switching off the monitor and turn it back on. I even shut down the entire computer but the line would appear even on reboot. The problem stays as long as i dont give the monitor a whack on the side that is when it comes back to normal. I have searched the forums but did not manage to find anything of much relevence.

One more thing earlier i would reattach the connections a bit in case the flickering persisted for too long and it would become ok but start again after about 30 mins

For information i am using a LG Studioworks 552V 15 inch CRT Screen on a ATi Radeon Xpress 200 series graphic card

Any help would be most appreciated.
Thanks

Question: flickering monitor

This is my daughters pc, and this is her explanation. All i know about the pc is, its a Dell, skinny tower, ex NHS thats been wiped clean and XP reinstalled. 40gb HD and probably onboard graphics.Very basic. I figure there can only be 2 issues here, either the monitor has developed a fault (i'm trying to locate another to try) or its the on-board graphics chip. Should this be the case, i would like to add a graphics card, but how do i know if it will be compatible? No gaming req, just a basic card will do.

Check cable connections are tight too and try another cable if possible.

Question: Flickering monitor

I have a new win xp home pc with a 4+ year old CRT monitor. As of the last couple days, the monitor will begin flashing unreadably after about 10 minutes of use until I put it in standby mode for a couple minutes. However, it won't stay in standby mode more than 10 minutes or so...I'm running NAV and firewall and something always seems to pop up - I've turned off live update, which gets me up to about 10 minutes. Now that I think back on it, I've heard the monitor turning on and off quite frequently, and am trying to figure out it that's something to do with my flickering/flashing. Any ideas how I can get my monitor back? And what about standby? Can I keep the thing in standby, or do I need to give it up? I currently have it set to go into standby after 15 minutes, although I usually manually put it on when I leave. The monitor worked fine for the first couple weeks of use with this box, and worked fine for the last four years with W2K.

I have an EVGA 7600gt that has two DVI outputs, and I have a monitor connected to each. The problem is that whichever monitor I have set as the secondary one flickers whenever I open up the nVidia control panel or click the task bar icon. Has anyone ever had this happen to them, and what could be wrong?

Note that it doesn't matter which monitor I use as secondary, I've tried switching them around.
 

Answer:2nd Monitor flickering

Try different drivers. I've there are some wierd issues with some drivers and some cards. For example if I open the nvidia control panel at all after initial setup it screws up video playback, everything becomes really dark and can't easily be fixed by making video adjustments in the control panel, only way to fix is to change drivers.

Are you using LCDs or converting dvi to vga for crts?

Question: Monitor Flickering

Using ASUS motherboard with 1.8 ghz AMD Athlon,
Elixir PC3200 memory 1 gb (actually 1024 but it only recognizes 1 gb)
Had a generic 32 mb video card, couldn't play some games, so I bought a 128 mb Radeon 9200 SE. Got monitor flickering, thought it was a cheap ENVISION monitor. SO I am using my mom's Sony monitor, Trinitron model, about 3-4 years old. Monitor flickering is still there. I upgraded the video card and this causes monitor flickering? I tried changing refresh rate, it goes up to 85. I decreased the pixel size on the monitor just now and refresh rate goes up to 100, it seems to be beter now, what is the weak link, monitor? Or can you tell? I have 350 w power supply I believe.Click to expand...


 

Answer:Monitor Flickering

I downloaded all drivers, tested with more than one monitor, both are used. The problem is most evident when the screen is on a white page, like google or yahoo, when the page is all white. Flickering is worst then. When the screen is dark, flickering is not a problem, this is after I upgraded from a generic 32mb ram video card to a 124 mb raedon.

Question: Monitor Flickering

My monitor colors are flickering. Every few seconds or so the white flickers and is replaced with a dull yellow color.

Recently I replaced the fan on my video card with a different one. We had to splice the connecting plug onto the new fan from the old fan to make it fit. The new fan was from an older video card.

Could this be the problem? Would I be better off without a fan? Originally the video card had a fan and a heat sink.

Could this problem be from overheating, or a power drain or something from the new fan?

Is my video card dying?

Is this no big deal?

I just recently replaced the motherboard and the hard drive on this system.
 

Answer:Monitor Flickering

The problem is unlikely to be related to the fan.

The problem sounds like momentary loss of either one color signal, or that one color is being lost intermittently within the monitor.

The most common cause is a poor connection with the video cable, make sure its fully plugged in each end.

The next most common cause is a poor solder connection -somewhere- in the monitor (also known as a "dry joint"), these are almost impossible to locate as to the naked eye they often look fine.

A gentle (but firm) whack to the side of the monitor case can influence the latter. If that is the case, a new monitor would usually be cheaper than fault-finding.

Posting the monitor make and model would have been a good idea though.
Check the cable first.

I know that this is not a necessarily Windows 7 issue, but I have no idea what is going on here. I recently bought three LG E2242 monitors for my system, and one of them will inconstantly stay on. I am fairly certain that it is not the monitor as I have switched the monitors to see if that was the case. I think it may have something to do with how I have everything set up. I have the monitors plugged into my Radeon HD 6850 (two using DVI, one using an active Display Port to DVI adapter). The one thing that I thought of was that the signal from the Display Port one the graphics card was not getting enough power, or getting just too little power... but that doesn't really seem that feasible (bear in mind, I am not a computer engineer, so who knows, hopefully someone out there ).

TL : DR -> One of my three monitors flickers on and off, not the monitor or the cable, could be the adapter or the graphics card.

Please any help on this would be greatly appreciated.

I have a X2gen monitor and it keeps flickering on and off every other second.. Does anyone know if I need an updated driver for it and so can you give me the link? Thanks.

Answer:Monitor Flickering

This company went broke in 2007 and support is no longer available. I quote directly from this site :

http://forums.driverguide.com/showthread.php?p=87373

"This monitor did not ship with a driver because it's not required, it's plug and play with Windows XP.
If you're having problems with your monitor display, maybe you need to update your video & graphics adapter driver"

If I were you, I'd take the simpler approach and try another monitor,.. they're quite cheap now and most people have a spare old monitor or two tucked away in their garage.

cheers
