The KT7A has a temperature-controlled safety switch which shuts the system down if the processor temperature climbs too high. Your manual should have the temperature ranges. The BIOS screen should display processor temperature, so run Quake for a while then reboot and check your processor temperature in BIOS setup. If it's high, then check the cooler on your motherboard to see if it's working OK.
