No signal/Safe mode not working

Please forgive me for being a noob.
Every time I boot up my PC, after the XP icon loads-the one with the big Windows XP icon and blue bar- My Monitor displays "No Signal"

This is the first time I encountered a problem like this. the last time this happened to me is when I updated my Video card Driver, which was not compatible. But the problem was resolved. So now I checked the system In VGA mode, and it's perfectly fine, drivers are installed and the cards are working. what could be wrong?

My theory is:
I set the resolution too high

So I tried to change it using safe mode. But another problem occurred: Safe mode hangs on the last sentence/entry.


I'm not fond of big Icons, and can't work properly
so right now I'm utterly frustrated :) :) :)



Any answers? :)

Try doing this:

Restart your Computer >> press F8 continuously until the boot option shows up.

Select "Disable automatic restart on system failure" then press "Enter".

Then observe your computer:

1. Does a blue screen show up? (Write down the error codes) If not;
2. When the "No Signal" appears on your monitor, do you see any indication that your CPU is still powered up, e.g. keyboard lights still on, CPU fans are still working?.

OK, no blue screen?

Restart your computer again in VGA Mode (since it is working).

While in VGA Mode, change the resolution to your optimal settings. (32bit Color and 1024 by 768 pixels).

My attempt was a complete fail, after I set the screen resolution in VGA mode then pressed enter, everything went blank then words flashed on my screen- "Signal Not Found" :)

I was thinking of backing up all my files and Re-install the OS, if, I can't find another way.

Is there a possibility that this is caused by a Virus?

I would try re-installing the video card driver.
VGA is windows default and is not using the card.
Either the drivers are corrupt or the card has failed.
You could also try reseating the card in its slot.
Make sure you power down and unplug the cord. Also touch the computer frame as you touch the card.

OK so. I will remove the video card from its AGP slot. clean it's contact points-the gold plates- with an eraser. plug the card back in, and try re-installing the same version of the driver.

Why do I need to touch the frame when I remove the card again?

Anything else that I should be aware of?

Thanks for your post! :)

Try re-seating/cleaning it first.
Then try the drivers.

Touching frame of the computer will put you at the same potential as the computer and the card. This is so there is no static that could potentially short a component on the card.
This is to be done with any electrical component.

The best way is to be grounded with a ground strap.

A anti static ground strap attaches to you and the computer.
