Overclocking and PSU turning off my comp?

[FearoftheNight]

Hey can this happen? I was playing CS and stuff today and suddenly my house pointer freezes...10 secs laters my machine turns off. I'm running overclocked machine w/ a lot of stuff. Can this be happening? I got a cheap RAIDMAX that came free w/ case.

Yep...Usually it just reboots but I can see a shutdown...Check tmps as well as some mobo have a shutdown temp...CS is a strong stress testing program and could have hit some high temps and if you were at the cusp that could have taken you over the edge....Power issues can lead to freezes as well...

I went into bios and it said 70s....asus probe reported 44.

Hmmm...Also in the bios does it have a feature to shutdon at a certain temp??? It should and if I remember correctly 70-75c is where it is usually set....shut this off and see if problem continues....

P4 or AMD??? If amd be wary of heat....The p4 will just throttle if it is in fact a correct high temp but no shutdown....

I would check that temp with a another program seperate of asus pcpprobe to verify it....

Have you flashed the bio recently....reset the cmos and see if temps change???

Take it from me I suffered for many months trying to figure out what my reboots were coming from. I had a 300wPSU with only 8amps on the 12v rail. Got a 430 Truepower PSU with 20amps on the 12v rail and no more problems

Not reboot I mean. But just shut off. Could it be PSU?

yes it could but i would look at the heat thing as mobo bioses liek I mentioned often have a shutdown temp and it will shutdown and not reboot...

You might need to also maybe raise the CPU voltage core as it might not be stable.

how about just telling us what mobo you have lol
if its a newer asus (since you said pcprobe, im assuming its an asus), it has C.O.P. (cpu overheat protection i think its an acronym for...) which automagically shuts down the comp when temps get too high for cpu

if bios reports 70C, but asus probe reports 44C...im thinking something is so very wrong lol...

maybe bios is reporting on die temps and probe reports socket temps?

It is stable. Motherboard is Asus A7N8x Dlx w/ voltage at 1.75. It had no problems before I ran prime95 w/ playing games at stuff for 12 hr periods without any crash or lockup.

did you even read my post loL?

from asus website:

ASUS C.O.P (CPU Overheating Protection)

ASUS C.O.P (CPU Overheating Protection) is a hardware protection circuit that automatically shuts down the system power before temperatures go high enough to permanently damage your CPU.


id say its possible that would be the symptom, as 70C is kinda high (almst what amd calls critical)
do you have that qfan thing enabled?

 

[FearoftheNight]

qfan? nope...set my smartfan ii to full blast... and there no reason for shutting down due to temps...12 hrs of prime95 running in the background while playing music is more stressful than 1 hr of counterstrike?
