I'm having a problem with my monitor displaying the message "no signal" when I turn on my PC. It happened since getting a BSOD several weeks ago but this may be just a coincidence. I have tried several monitors and they all show the same symptoms so I know the monitors are OK as they work fine on my other computers. I know the computer is working ok because I can still type in my passwords and the hard disc spins and I can connect things like my iphone and it will start syncing.

I sometimes get the PC to wake up the monitor if I take out all the USB cables but this doesn't always work, I have tried removing the graphics card and reinserting and this occasionally works too. I am getting to the stage where I leave the PC on because I know if I turn it off or restart, the monitor will probably not come on.

I updated the driver for the graphics card but this hasn't improved it so I'm at a loss now what to do, apart from try a new graphics card. I currently have a nvidia geforce 8800gt graphics card.

Well, I certainly does look like the graphics card is your problem. Can you swap in another card from one of those other computers? Before buying a new card, since the graphics card is often the most power hungry device, I would probably swap PSUs for test first, just to make sure yours is not struggling.
