As computers get older they invariably start developing faults which causes reboots. Whenever my computer keeps restarting there are a number of checks which need to be done in order to work out what type of hardware or software faults actually causing the problem. This initial research can help focus you in on what type of repairs will need to be made.
Always begin by checking that internal components are not overheating. In particular, the CPU and hard drive can be prone to getting too hot if the vents are blocked or there is dust inside the PC. Check the BIOS menu to see what the CPU temperatures are and if the error too high (according to manufacturer guidelines) then open up the PC and clear out all dust and check that the heat sink is correctly attached to the CPU.
If your computer keeps freezing as it is starting up then is quite probable that the registry has been corrupted one way to resolve this is to resort to using the last known good configuration. This is available from the advanced Windows startup menu. This can be accessed by hitting F8 as the system is starting up. It will revert back the operating system to an earlier version of Windows registry and will take effect when the system restarts.
If your system is able to start up then the event viewer log (start/run/eventvwr) can highlight what sort of error messages where logged prior to the restart. This is often the first thing I check when my computer keeps restarting as it details exactly what piece of hardware or software through an exception message. This can then be researched online and a suitable fix found.
Finally, some of the more hardware-related checks to do involve doing a bad sector repair of the hard drive platters (e.g. using Windows own error checking tool) and also opening up the Device Manager tool to check that none of the hardware components or conflicting.
