I have a Pent. 150. It was working fine last night. This morning it started re-booting after the memory check, just after it gives the name and date of the Award Bios. It will keep doing that until I turn the power off. The Delete message to enter CMOS is at the bottom of the screen, but will not let me enter CMOS setup. I put in a new power supply, to no avail. I checked the memory to see if it was seated OK and moved the memory around, but no dice. What could be causing this?
