Problem installation video card
Hello Virna, i have that exact graphics card and dell GX270 desktop here at home, tho it has been awhile since i removed the Nvidia PCI card for a more favorable AGP card. From what i remember, first check your BIOS (hit F2 on startup) and select integrated devices, scroll down and make sure your default video output is either PCI (if available) or AUTO) exit saving changes. If that yields no result. Plug in a second monitor to your old integrated video output, if you can view windows after bootup from there, then you can install the proper Nvidia display driver for windows Xp (available here: http://www.nvidia.com/object/winxp_175.19_whql.html ). After installing, right click on the desktop, select properties, display settings tab, and make sure the Geforce card is the main monitor and the desktop monitor. Click apply, unplug the integrated VGA output, and restart. Hope this helps.
