My specs : Win Xp Pro / AMD Athlon 2.4 / 1.5 DDR PC 2700 memory / 2 IDE hard disk / nVidia FX 5200 card /DVD-RW Drive...yeah only that. PSU is 350 watt - does it has enough power to drive all these ? I notice lately too much or too fast mouse clicks will auto reboot - cleaned all heatsinks and re-seated my coolers and double checked whatever things that would cause overheating.Thought was my video card but swapped cards still persists..doesn't really happens all the time but sor of pain in the **ss esp.when burning dvd and the it reboots in the midst of it. Any idea ? I don't mind purchasing a new psu but don't have a spare for testing....or could it be something that is not a psu...?
