Hey guys im in need of some help. I just built a computer last night but for some reason the computer shuts down by itself right after i get a CMOS checksum error. I can get into the bios before that and load defaults, but that only gets me to the OS loading screen where it shuts down on me again. The system has 2 HD's, 2 optical drives, an x300 video card and a athlon 3800 X2; its all powered by a Antec 380 PSU. Can anyone think of any reason why I keep shutting down?
 
I might be mistaken but i dont think a 380w power supply is enough for your box, try a bigger psu (borrow one from a friend and do the test)

That makes a small wattage difference. Try stripping it down to one hd, no opticals, one stick of ram, no pci cards.
 
run it with only 1hd, cpu and memory.

during shutdown u can tell if it's the PSU as there'd be a clicking sound before it shutsdown.
 
just tried doing this, same thing happens
:(
im really puzzled by this, ive built so many computers before and never had this much trouble, i just tried pulling the bios battery with no results.
:mad:

try another PSU. then try another hdd.

basically strip it down to motherboard, psu and cpu. -w/o memory u can heard beep sounds. then install memory, reboot. if it boots it'd say no ntrl driver something or chose right boot device. then install hdd. if it shutsdown during hdd is installed try another hdd.
