I would check for the following: * ssh from the remote machine --- this checks the extent of lockup. It may well be just X locking up, while kernel is still alive and well. That would be the issue with graphics hardware/drivers. * reproduce the problem with a LiveCD, prefferably different distro --- this checks for hardware vs. software fault. If for ex. Knoppix locks up too, it's definitely a hardware issue, independent on the OS in use. * if it's a hardware issue --- upgrade power supply, downclock the processor, change the motherboard, remove components from the box one by one until you find the culprit. * if it's a Fedora issue --- boot with nomodeset kernel option, disable ACPI, change graphics drivers, boot older kernel, try to narrow down the app that triggers the lockup...
