Monitor Loses Signal
Oct 28, 2008
My computer has been doing this for awhile, it works fine, I can watch videos on it and everything, then I go play a game (Call of Duty 4 on max graphics) then after a minute or two my monitor would go blank (Blue in this case since its HDMI) and lose the signal to the graphics card, The connector isn't loose, nor is power and I must reboot to get the signal back.I have upgraded the computer with this graphics card, I did uninstall old drivers but maybe not fully.Another perhaps unrelated problem is that whenever I restart, it no longer detects my graphics card, resolution: 800x600, 4-bit, I must uninstall all my drivers, then reinstall them and it fixes the problem.

I have a dual monitor setup on my PC. Today, when I boot it up, the main monitor displayed all theboot information and startup stuff, however, when the system SHOULD have gotten to the user login screen, the main montor came up with "no signal." The secondary monitor at this time will still show my mouse moving around on it, and I'm able to move the mouse over to the main monitor but I can't see anything.I've gone through a few basic manuevers to see what was wrong. I booted in safe mode and logged in to my mai account and attempted to change the other monitor to the main one; However, Safe Mode does not appear to supoort multi-monitor and I couldn't change this. After that, I attempted to VNC into my computer with the notebook I'm on now. When I came to the login dialogue box, the only account I could log into was the invisible "Administrator" account. My main account, as well as a temporary account I created for testing, both came up with an error "Cannot access due to user restrictions." My theory is that because all of the accounts which are actually visible on the login screen seem to not be working, the login is bugging and not outputting anything to my main monitor (since I have verified both monitors and connections to be working properly).

I have been experiencing intermittent bootup problems with Windows XP. When this happens, the XP splash screen appears(blue line scrolling) and then monitor loses signal and reboot occurs. This can cycle several times, even if I choose the option of starting Windows with last known configuration that worked.

Got a problem, I have Acronis True Image and I have restored the settings stored which is about 2 years old now. I have done this loads of time to clean the pc and start afresh. Problem is i am now unable use computer - "no signal" on pc showing up. Anyhow i have been fishing about and it looks like the graphics card is not working, there is no sign of it in dxdiag/display. I know the graphics card is Radeon 9200 SE AGP and i also have the disc, but i still cannot get it to work, I am safe mode at the moment.

I entered my XP run PC into standby yesterday but as it would not resume later, I turned it off using the power button. Now it won't wake up again. I have been sitting in front of a blank screen for 3 hours. The monitor displays "no video signal", so I exchanged monitors but the other one stays blank too. The pc appears to be running but will not boot. I have entered Windows CD to restore but it won't even boot that.

I currently look after a network of 20 computers, some running windows 7 and most running XP sp3 (32+64bit) Mine is 32bit.
I joined my computer to the domain after a fresh install of XP. Here are where the problems started. After about 15 minutes I lost internet connection. About 20 minutes later the computer could not open or close any programs without killing the process. Then I lost network connection and was left with only the task manager running and no explorer open. I managed to install SP3 after downloading it on a seperate computer and running it on a disk.

My main computer's (XP, SP3) Internet connection is shared among 3 other machines via ICS. However, one machine (XP, SP3) - which runs a couple of P2P programs - usually loses its connectivity (even file sharing) after a few days. I'm running Kaspersky Internet Security on the main computer. I've tried disabling it (for testing purposes) to no avail. I've also disabled Windows Firewall on both machines with no improvement. Using a router is pointless because it freezes after a few days (due to the P2P programs). I've tried 4 or 5 different routers (even the "good" brands).
Is it simply an overload in terms of the number of connections possible? Does ICS, in principle, face the same problems as a typical router? Because I've even tried reducing the number of P2P programs to just one and also limiting the number of connections it makes. (Not to mention "fixing" the 'tcpip.sys' limit on both machines.) Any ideas what the problem could be and how to fix it?

My mouse keeps hanging up and clock loses time when not running in safe mode. Not just the mouse really, but nothing at all works. When I boot normally (not into safe mode), windows can take forever to load due to this. On last boot my clock lost 10 out of 15 minutes uptime and I had to manually power off even then. I am running Windows XP Service pack 2 on a AMD Athlon 64 3800+ system with 1214 mb mem 150 gig hdd.

This is not a desktop recovery error. While using the computer, for example using IE on the internet: all of my desktop icons and access to anything ie. start menu and right click on desktop no longer works. I can continue using the IE open window, but to get my other programs back I have to shut down. The desktop wallpaper still remains.

Screen goes blank, "NO VGA signal" displays, then everything shuts down. This happened every once in a while for a month or so, but now almost every time I'm on the computer. SOmetimes after I've been on a long time, sometimes after only a few minutes. I usually lose everything, although sometimes some of the programs I'm operating are still up when I turn it back on.

When Windows adds a new monitor using the standard driver, can it detect the aspect ratio? When I hooked up mine, all the resolution choice were for 4:3 monitors. There were no widescreen options. It should choose the monitor's native resolution on its own if the monitor is an LCD.

I'm guessing this should be in the hardware section, but I want to make sure it's not a software related issue. To give you the complete story here, I was playing Madden last night when all of a sudden my computer rebooted by itself. No warnings or anything, just a black screen for a quick moment and then a reboot.
I thought it was a bit strange and waited for it to boot to see what it had to report, but to my surprise it booted up windows, got to my desktop and then did the same thing again, so I just let it sit there till today

i bought the new game, Lord of the Rings Online. Works and installs perfectly however, because i have a weak connection sometimes an error message comes up saying you have lost connection, so i would keep trying untill i manage to get onto the game successfuly. Then i would get another problem which i am sure it is to do with my graphics card. As i am loading the game and enjoying the introduction video, my computer screen would go black and a message would appear saying 'No Signal' with the computer still running. So after seeing this message i would assume to restart the computer, there is no other way of getting it back to the desktop. I did this quite a few times maybe about 6times. After pressing the restart button for the last time

I have a old Dell computer which I brought a 24" Dell HD monitor. I upgraded it with a new graphics card which has both VGA and HD capability hook-ups. Now we have a new tower to go with exisiting 24" monitor. My problem is I can not get a old standard VGA monitor to work with the old system listed above. When I plug in the the VGA monitor plug in the VGA outlet in the old computer I get no signal to the monitor. What do I need to do with drivers or other wise to get the old computer back to being able to be used with the old VGA monitor?

My explorer has gone nuts. It will run programs, run shortcuts to anything but folders and the real problem is that it wont open a signal folder either by explore or open commands. I've reinstalled WINXP off the CD as update, nothing happened. I've ran the steps listed in the last forum. Nothing has worked. I'm desperate. I'm running WinXP Professional on a basically 7 month old Dell comp with 512RAM and a 2.4 GhZ Pentium in it. I'm lost at what to do.

A friend of mine needs win 2000 Pro boot discs. I don't think this is illegal as a microsoft site says if you have problems to make from a friends. He is the only person I know who has it. Need the discs to access his system. Probably infected. Cant get it to start, shutdown, nothing. Sometimes monitor says no signal. Sometimes works. Checked wires. Put in an old spare video adapter card, starts to work fine but freezes before I can do anything. I do not have a floppy drive so I need to be able to burn them to a CD.

I replace my old LCD monitors (Dell 1905s) with new acer P223w's. I have a dual monitor display.I power off both monitors with one switch that cuts off the power. When I do this however, Windows makes the sound like a device has been disconnected and it messes up my monitor settings. This is very annoying and it didn't happen with my other monitors nor does it happen on my other Windows XP system with different monitors. It's like Windows is trying to be "smart" by thinking the monitor is gone. I do not want Windows to care if the monitor is powered off.

I wonder if it is possible to switch off the computer's monitor manually.
System Control / Energy provides the possibility to define how long the
computer must idle to disable the monitor. I want to do that "by hand". Is
that possible?

friend whose computer has crashed the screen had frozen. He could do nothing except reboot it using the power button but on rebooting, there was a 'no signal' message on a black screen. We have checked the monitor connections (the monitor works when connected to his second computer) and even replaced the video card but of course this made no difference (no signal) We've taken out the HD and installed it on his second system. Does this mean that the most likely cause now is the motherboard/bios or is there something wrong in our approach/deductions

I have problems if I try and run the display settings above 800x600. I was wondering if this would be fixed if I upgrade the firmware settings and if so where would I get these upgrades? Whenever I try and run it at a higher display setting all I get is a thing saying "Signal isnt compatible with this display setting".

when I booted up Windows XP it would only run up to the Windows loading page. Where you see the Windows logo and there is a bar running. After that my monitor either goes blank or gives me a "no signal" message. So I decided to reformat my hard drive and re-install the OS. Well now it only turns up the background, where I could see the background image and the mouse. But no start bar no nothing.
I am running Pentium 4 Processor. Intel Desktop Board D915PBL Windows SP1

I've got an HP notebook with Windows XP. I just went out and bought an s-video cable so I can use my TV as a second desktop, but I can't get the damn thing to work and now I want to kill. Here's what's happening: when I go into display properties and screw around with the 1 and 2 monitors and try to "extend my windows desktop", my monitor turns off for a second and the TV blinks like it wants to work, but then the monitor turns back on and the TV just stays blak. Same thing happens when I do the FN+F5 thing.
