I've had an old Pentium 266 Mhz lying around and I'm trying to get it running. It has a generic Motheboard. I can access BIOS without any problems. When I go to restart it does the memory check and then detects the correct hard drive and cd rom drive and then it just hangs. After about 5 mintues it starts to beep. One continuous long beep. Is this PC toast? Is there anything I can try to get it working? Thanks! 🙂
