Ok, so I bought a new monitor a few days ago and its been working fine. I turned the machine on today and it was still working fine, it showed the boot screen and it showed the xp load screen but when it was supposed to go on my desktop it went blank and claimed there was no signal. Windows definately loaded aswell because i heard the start up tune.
This is a link to the monitor

Any suggestions (bearing in mind it has worked fine for 2 days and I set the resoloution to its optimum the day I got it 1280 × 720)?
