My PC reboots by itself and warnings have appeared asking me to run Chkdsk

My desktop PC sometimes reboots of its own accord. Recently, at startup, dire warnings appeared asking me to run Chkdsk with a surface scan. It has quality components - a 350W power supply from http://www.quietpc.com/, an Asus A7NX8 Deluxe motherboard, and an AMD Athlon XP 3200+ processor. It seems to be getting worse with time. I have tested the AC mains power cable with a continuity meter, and removed and reseated the memory modules, the hard-disk-drive power connector and connection to the motherboard. The hard drive is a Samsung SP1213N, so I tested it with Samsungs hard-drive diagnostic utility, which reported no problems. The surface scan performed by Chkdsk was successful. I have also removed and replaced the silicone heatsink compound between the processor and the cooling unit.
