but fails to display video on others - noticed one of the four cores was listed as 'not available' under 'Signed Drivers' listing in System Information - have updated all drivers and fixed that but without change in primary problem. nVidia GTX295 4 GB RAM XP Pro - 5.1.2600 SP3 build 2600 DQ965GF MB SMBIOS v2.4
No other devices problems or conflicts found. Steam games play fine. Crysis plays once antiviral disabled.
Example older game is from Eidos - - Thief Deadly Shadows which installs but upon launch, screen goes black and can hear audio played from splash logos of vendors as they normally play - not crashed but need to end process in task manager to quit.
Any clues?
