I downloaded and installed Fedora 5 onto an old computer (P2 450 MHz) and it ran fine. Ran yum update a few days later and ever since then, computer would randomly go into a sleep mode and would not wake up with mouse or keyboard. Tried changing all power settings but this did fix problem. Unable to update BIOS. Bought parts and built a brand new computer (Athlon 64 x2) and bought a new monitor. Installed Fedora 5 and it ran fine until I updated it using yum update. Now I am getting the same situation, computer goes into what seems like a sleep mode and it won't come out of it. Only thing to do is press the power button to turn it off, then back on. Any help or suggestions?
