Ok, before starting I'll be honest. I'm not the most techniclly minded so this may be something simple, but any help would be appreciated as this is driving me mad. The other day I re-formated my system and re-installed windows cos of software problems. I haven't done it before, but found an *****s guide on the net and it was all straight forward and worked fine. Prior to this, all hardware appeared to work fine and my monitor (ACER AL1916W) displayed perfectly at 1440 x 900 resolution. However, although the monitor displayed fine plugged into my graphics card (INNO3D 6600 AGP W/256MB DVI TV DDR), after the re-installing I was unable to display at 1440 x 900. So I reinstalled the drivers for my graphics card. This appeared to also go fine until it asked for a restart of the system to finalise the installation. Upon restarting, and now everytime I boot up the system, the screen displays all the usual system info and option to access the BIOS screen and then goes on to show the windows XP loading bar. This disappears and then there nothing. Just a black screen with the monitors message of "NO SIGNAL". I have tested this on a few different monitors and all give the same response. Anyone know why this would happen or, more importantly, how to fix it? I've googled the problem but the only answer seems to be "send the card back and get a new one as they've sent you a defective one" but I've had this card for about a year and never had any problems before. The computer has been reformatted by a technician in the past since this card was installed and all was fine after that. I'm a bit baffled really... Any help would be most appreciated.
