I have the following Pc: AMD Athlon 64 3800+ 1MB Cache SKT 939 Processor MSI K8N Neo 4 SLI/Platinum Chipset Nforce 4 Ultra SLI Mother Board. Latest Drivers 1.5GB DDR Kingston DDR400 RAM. Sapphire ATI Radeon X1900 XT 512MB DDR3. Catalyst 6.2 Drivers. Creative Sound Blaster X-Fi Xtreme Music. Latest Drivers Thermaltake Power Supply 500W. Seagate Serial ATA 300GB. Gamepad Logitech Cordless Rumblepad. Latest Drivers DVD-burner Lite on 16X Dual Layer. 22 inch COMPAQ Monitor. Wireless Microsoft Keyboard and Mouse. Latest Drivers Windows XP PRO SP2 5.1 Altec Lansing 251 Speakers. The Pc boots ok, but when I execute a game, lets say Quake 4 or Doom3 instead of executing them inmediatly, it takes 16 secs. to show the first screen: "LOADING GAME". Once you are in the game it works ok, no problems at all then when you exit the game the desktop freezes 10 secs then everything changes to normal. When I had my old Geforce 7800GTX, I didn't have this issue, it happens just with the ATI X1900XT. Can you help me?
