I have a new PC with AMD Athlon 2800+ XP processor, Asus A7N8X Dlx PCB Ver.2.0, MSI AGP - GeForce FX5200 -128DDR RAM, with Samsung 2 no.s X 512MB ddr400 dual channel RAM, the machine reboots randomly though the machine is left idle with out running any program. I am unable to trace the problem, I have tried changing RAM modules, changed the Display Adopter , but the problem still persists. Can someone hellp me?
