Can someone help me pwease...:

 

I've recently updated some drivers for my Optiplex GX270 and now the machine won't startup properly. It comes up with the WinXP startup screen, then goes 'dead' on me. No error messages, just the monitor stating 'No Signal'... Eventually it will startup after having to go into 'Safe Mode' and from there restarting the machine..

 

At first I thought it was because I updated my BIOS with update A03, then tried all the updates up to A07 for BIOS from the Dell Website, reinstalled the whole OS, where Windows update offered me 2 updates for Dell, the network drivers and the graphic drivers, which I installed and my machine is still not starting up properly... Also tried to roll back the graphics driver but no luck

 

Is there a patch, or which driver should I roll back to get it working again?

 

Thanx in advance..
