Custom Build - PC randomly turning off (Possible overheat due to unlocked cores))

post #1 of 10
Thread Starter 
My brother and I built a PC a about 2 months ago and as of late it has been randomly turning off without warning.

It has happened while playing Minecraft and during WOW (total of 7 times in a last few weeks)

His chip set is a AMD Phoenom II x4 B60 processor.

He was messing around on the boot up screen and he unlocked all his cores (he said it was 1-2 step process, but does not remember how exactly it was done). To tell the truth he did not know what he was doing. (as do I as this point)

I downloaded a few temperature monitoring programs with no real luck.
Realtemp - Did not support my chipset
Core temp - does not show temperature of the cores for some reason, like it couldnt find them.

I noticed the fan over the CPU does not line up 100% with the air hole cut out on the case.

At this point, I not too sure what to do...
Can I disable the cores to original factory settings?
By unlocking cores, would I have to add extra cooling fans?
How do I disable the extra cores? or should I get a bigger fan?

Any help would be greatly appreciated.

Fill out your specs in the user signature so we can "see" your setup.

System shutdown under load = classic psu failure.

When you unlock cores it disables temp per core and only shows socket temps. Also the cooler that comes with a x4 is much bigger that a x2 so if that didn't get a upgrade that could be your problem.

Download and run core temp. What temps does it reach when playing a game? The stock AMD heatsink-fan on the lower end chips are inadequate for unlocked quad cores. An aftermarket cooler is likely needed.

Another possibility is that the unlocked cores are unstable. You may have to go in the BIOS and return the CPU back to default.

I experienced it my self and have read else where, when you unlock, it does not show your core temps... it reads 0c/?

When you unlock cores it dosen't show temps correctly anymore. So you really have no idea what the temps are and if that's the problem. Can you disable to core unlock?

Yes to revert you're bios back to default, All SHOULD be well, you can hope.

-Unless the the cooler isn't mounted correctly and now the summer is making you overheat.
