I have Win XP Pro SP2, 102 Intel motherboard, DDR2 512 RAM, 2.8 Dual core processor. An Internal modem, 256 Mb GeForce 7300LE PCI Express graphic card. On my old PC all my original games used to work fine (Cricket 2005, Battle For Middle Earth, Unreal Tournament 2004, Far Cry etc.), however with my new PC with the above configuration, I am unable to play any game for which the playable CD is required in the drive. Everytime the games start and tries to detect the CD in the drive; the PC instantly restarts. Is there something wrong with my configuration or is SP2 interfering. Mounting images did not work. I have the lates Antivirus definition files and have scanned the drives with Ad-Aware professional, still no luck. PLEASE HELP.
