Hi, I got a problem with my ne Ati Radeon 1950 Pro. My complete system: Carte graphique: Ati Radeon x1950 pro Écran: Acer 19in Wide Boîtier: Antec Sonata III (power suply 500w) carte mère: Asus P5k atx LGA 75 etx... processeur: Intel Core 2 Duo E6750 mémoire: Corsais XMS2 PC2-6400 DDr2-800 2x1GB disque dur: 2xWestern Digital Cavier SE16 250GB SATA2 7200RPM lecteur dvd: LG GSA-H55L clavier+souris: Logitech cordless internet pro desktop carte réseau: Linksys WMP54G wireless PCI adapter The problem is when I boot, after the logo of windows XP (loading) the screen get a No signal message but I can ear the sound of windows. This is really strange, since I didn't change anything on my computer (I had the 7.9 driver and all was working fine since today). I tryed many thing to resolve the problem! Get out the card and put it back. No change. After I loaded windows in VGA mode. It's working, but when I want to put the display in 1440x900, the screen get the No signal message. Same thing when I put the refresh rate at 60Hz. I tryed Installing the new driver. I loaded in safe mode, uninstalled the driver. When the driver are all uninstall, I can boot windows XP without problem. But after I reinstall the driver (7.10) after the loading the screen get the No signal message! I searched the knowledge base and saw that there was a thing for Acer, but the page isn't there anymore ... Anyone experencied a similar problem?? Solution ... I CAN'T put my resolution in 1440x900 in VGA mode with the good driver installed why?? :'( Thanks for your futur help. I need my computer!!
