Hello this is what happened, My video card worked fine ages ago and it never had anything wrong with it till i turned it off and went to school and then i came back and turned on the computer and i got this message on the screen that said this: http://imgur.com/KSVyCR6

It would work fine if i turned the computer off and on a couple of times and nothing would be wrong apart from it saying that it restarted all my video card settings and it would say that every time i would play on a game

till one day when i came back from my dad's and turned on my computer and it did come up with that Signal error screen but i turned it off and on lots of times and it would
not go off the screen and it would keep showing that screen but the numbers would change sometimes but what i had to do was go onto my second video card because i had a ATI Radeon 9600 video card and when i updated it i got a ATI Radeon 9600 Second and i just used that by going on to save mode and disabling the original video card and enabling the second one and the second one works fine but i can't play games that use a lot of graphics but now when ever i try to use the original video card it wont come up with that screen anymore it just comes up with nothing and it says 'No signal' 

What is wrong with the video card, I did nothing to it but i did have a look at the bios one time but i don't think i did anything but the video card worked fine and then one day, Gone

Is there a way to fix it or do i have to buy a new video card

Alrighty, this is an interesting one.  The signal error can happen for any of these reasons:

• Your video card's horizontal or vertical frequency is too high or too low for the monitor,
• Your resolution is set to some setting that the monitor doesn't support,
• The signal from your video card has become too weak for the monitor to read correctly, or
• The monitor's input circuitry is failing and can no longer handle the signal from the video card.

Given what you said about being able to restart your computer and have it come back up with a message saying your card was "restored" to certain default settings, I'm guessing that your card is malfunctioning, sending a bad signal to the monitor, and Windows occasionally can detect that it's malfunctioning and reset it to defaults.  Now that it appears to be doing this all the time, I'm guessing your card has just plain died and needs to be replaced.

 

Just a note on those numbers on the monitor: The frequencies seen there don't match up to any known VGA standard I'm aware of - I should be able to find numbers reasonably close to those for any standard resolution, but the vertical scan frequency looks to be extremely low.  It's possible it's trying to send an "interlaced" signal to the monitor, which would produce noticeable flickering on horizontal lines if your monitor supported it.  But the message you're seeing is the monitor saying it doesn't understand that signal, so either your card is completely out of spec, or it suddenly thinks your monitor can receive a signal that it actually can't.  (It's also possible the monitor is failing, but that would be less likely to cause Windows to reset your video card.)

Doing a bit more research.  I can't find any good resources that tell me why your vertical frequency (the "fV" number on the monitor) would be that low.  That display plus the behavior you described really does sound to me like the video card has just gone bad.

One more thing to ask about: Did you recently install or update new drivers for your video card or other parts of your computer?  It's possible that your new drivers aren't working correctly - if that's the case, you might need to uninstall the current driver (you can do that in Safe Mode), and install either a newer version if one exists, or the previous version that was working.  If this started happening on its own without doing any driver updates, then I'm going to stick with the failing hardware theory.
