I'm also having these random shut downs on my secondary PCs. Lets start with specs

amd x2 4400+ (stock right now) cooled by Thermalright SI-120
ECS KN1 Extreme (nForce 4 Ultra)
OCZ DDR500 Gold
320GB Seagate SATA
300GB Maxtor SATA
500GB WD SATA
Pioneer DVD-RW
Samsung DVD-RW
and Seasonic 600W


well this problem been going on for about 3 weeks. first i was blaming the PSU, so i replaced the 400W Antec with 600W Seasonic, didn't help.

now I'm running memtest.

any other ideas?

Vista? [EDIT, not a troll, asking due to ACPI differences.]

Can you disable auto-reboot on BSOD if it's enabled. If it's complete poweroff and not BSOD reboot then it's physical, likely MB, thermal, or unclean voltage to the PSU. Never seen bad RAM reboot a box without a BSOD/Kernel Panic.

yes its a poweroff shutdown, no BSOD

Could it possibly be the CPU overheating?

it coul, but 4400+ with thermalright si-120 and CPU being at 35C (according to everest) i don't think that is the issue

Must be a faulty mobo. You have exchanged PSU, and there is no other component that could do this..

You forgot to specify the GPU... my previous x1950pro (sapphire) did this kind of thing to a lot of people, including me. Though those were reboots IIRC.

You DO have a UPS right?
Agree with radek, could be the mobo.

Sounds like a mobo issue seeing as you've already checked your psu. Generally other hardware cannot shutdown your computer directly (only indirectly).

My old P5B-E plus mobo had the same issue, I had memtest running (mem was mucked up) and the pc would randomly shutdown, eventually it no longer booted, no beeps no nothing. The second P5B I recieved (RMA'd the old one) seemed to be fine, but after a while same sort of issues occured, random shutdowns, ditched it and got myself another mobo.

Ditch that motherboard and try another and see if it works.

What video card are you running ,I had trouble before with my computer rebooting and shuting down and it turned out to be the video card was going bad.

Well, if it isn't the CPU I would suggest a faulty mobo, like a lot of other poeple have said.

Had the same problem when my HDD was beginning to die on me. :-/

Be sure to check all connections, and do a disk checkup. :) Also check the capacitators on your mobo, and circuits.

(LOL just did a quick google search on random shutdowns and found a thousand threads about random shutdowns with macs :D)

You mention having the same issues on your other machines, which makes me think it may be more of a power quality issue. Are they all connected to the same power circuit?

My first guess would be motherboard as well. But you say it started around the time when you added the new hard drive? I don't know how a hard drive could cause it to power off though....unless something in it is faulty and causing the powersupply to trip off.....

"I'm also having these random shut downs on my secondary PCs."

That is the statement that threw me off. I assumed secondary PCs meant more than one.

in case anyone cares

problem was with 500gb WD drive.

ok summary

first a 300gb maxtor and 500wd where on the same power cable, a 250gb seagate was on seperate power cable. problem was there.
note: all used sata power plugs

then i switched cables a bit, 300gb maxtor and 250 gb seagate shared teh same cable. 500gb wd was alone on a different power cable then before. no change problem still there

then unplugged the 500gb, and for 4 days added 4 other hdds (3 sata, 1 ide) to teh computer, just to check if it was PSU fault, so i gave it a bigger load.
computer was on for 4 days with out a issue.

i then plugged in the 500gb WD into a my primary system. drive was alone on the power cable. in 3 hours the computer shut down twice with out a warning. a complete power loss.

this will be fun explaining to WD RMA department.
