A BIOS update must be specific to the chipset model, otherwise problems will be had with stability. And if the chipset design has inherent limits as to FSB regulation, then a newer BIOS will be of no use.. except for possible newer CPU/memory types, and larger hard drive capacities.
The original BIOS info string should carry over to the newer program, as to motherboard ID and BIOS branding.. but with an 'update' as to the version and date of creation. The name of the BIOS file update to be installed is proprietary to the motherboard manufacturer and model number update. Like an "item" number.
As to rebooting frequently, look to possible mechanical problems.. the PSU or heat issues with the CPU. Or memory pushed beyond its paging limits. The OS will dump and repage memory many times a second.. without the user being aware. But when a "major" memory dump such as a Kernel or System memory dump is effected, then a reboot or the BSOD will result. If the conditions for the OS are set to 'not reboot on memory dump', then an error message will stay displayed as to the cause.
F@H.. to solve mankind's maladies.. in our lifetimes!
