    I've got a problem thats left me totally stumped, i turn my computer on, and it boots up just fine, it goes through the load up screens, then the windows xp logo with the status bar underneath, then my monitor cuts out saying its not recieving any signals? The computer itself appears to load up fine, i mean it doesnt cut out or anything, and there doesnt appear to be anything wrong with the monitor, it shows the initial boot screens fine.

    I've had the PC plugged into a different monitor the last few weeks, and its been working fine, its only since i've gone to plug it into another monitor that the problem has come about. Unfortunatley i dont have the other monitor at the moment to try it out.

    Does anyone have any ideas of what might be happening??

    Thanks to anyone who can offer some advice!

    Cheers
    Liam

    your video card may have things like resolution and refresh that
    can't be done on that monitor

    in your video properties go set for a lower resolution
    and refresh.

    if that doesn't cure then test other monitor on machine
    and other machine on monitor

    Of course to try what johnpost suggested you will need to boot up in safe mode.

    I've been trying to restart in safe mode, by using the f8 method, but this takes me to a screen asking which device i would like to boot from and lists all the available drives? would this mean there's a problem with the computer or am i trying to enter safe mode the wrong way?

    That's OK. Some systems do that. Choose your boot device. The next screen should be the Windows Options screen. If not repeat the process, choose your boot device and immediately start hitting F8.

    I managed to get on in safe mode, but i cant open the monitor control program, NVIDIA desktop manager, it just won't open, so all i have is the display properties to work with i think?

    Any ideas?

    in display properties

    go to settings tab

    changeing the screen area value lower may help

    also

    click on advanced box then monitor tab

    change refresh frequency to 60 Hz

    in trioubleshooting tab

    turn acceleration down

    OK so the screen resolution is set at its lowest, 800 x 600, by default, due to the fact i'm in safe mode i assume?

    As for the frequency the only option i have in the drop down box is 'use hardware defalut setting'

    Have tried reducing the acceleration but still no change.

    so here's my problem again, just to clarify where i stand . . .

    My computer turns on and begins to load up, reaching the screen with the XP logo and thae staus bar at the bottom, and at the point where you would expect it to change to the login screen, my monitor then goes blank and says its recieving no signal, the computer however is still running fine.

    But if i start the pc in safe mode then it will load up fine . . .

    Tried another monitor this morning, same problem, so i can rule out there being any sort of fault with the monitor.

    My only problem with trying an xp repair, or indeed a clean installation is that i can only get the pc to work in safe mode, so can't connect an external drive by usb to backup?

    Any ideas for what my next move should be?

    Either video card is shot and cannot do more than post and you could boot to safe mode by tapping F8 repeatedly after hitting power button only choose "use vga display" and try to boot.
    If that works then it is a video monitor driver issue. if it doesn't then hard drive is "toast".
